This civilization is very strong, but the technology tree is a bit crooked.

Chapter 88 Absolute adsorption, perfect lithium battery recycling equipment

"With this membrane, the leaching and extraction of lithium battery recycling can be directly combined into one."

"In this way, it seems that there is no need for a large space, just build an integrated recycling equipment."

"Throw the battery here, and spit out the metal elements of various batteries over there."

"In the future, it will be further miniaturized, and it can also be installed in drones, oceans, the moon and other places to mine casually."

With this perverted biofilm.

Chen Yi quickly decided not to build a large-scale chemical equipment set, but to build an integrated lithium battery recycling equipment by himself.

"Before determining the equipment design, experiments are required to determine the adsorption efficiency and adsorption capacity of the biofilm."

"Also, the most important point is to adjust and improve the biofilm that absorbs all metals into a biofilm that absorbs simple metals."

Chen Yi looked at the property interface of the biofilm in front of him.

Say without hesitation.

This biofilm is so crazy that it wiped out all the metal elements in the periodic table.

It is not an exaggeration to call it a metal gluttonous film.

Evaluation according to the remarks of the system.

According to the conductivity and absorption rate of different metals, the metals can be classified and adsorbed.

But after several virtual chemistry teachers taught by example.

Chen Yi understood very well that even if the absorption rates were different, there would still be some other substances participating in most of the reactions.

This thing that reacts with it.

This can affect the texture of the material if not purified.

If you choose to purify and purify, the cost will go up again.

To solve this problem from the root.

Chen Yi can only adjust and improve this all-metal killing biofilm into a single-plasma membrane of a single metal
For example, lithium is needed, so lithium biofilms are taken out.

If you need uranium, come up with biofilms for uranium.

According to this idea and direction.

Chen Yi prepared a cup of solution rich in various gold elements in the laboratory.

Take a cut piece of biofilm, simply measure the area, and start the experiment.

"21.3 square centimeters, in units of 5 seconds."

Put the biofilm on the test platform, the instrument will automatically pour the solution, and the test platform will start to rotate at the same time, so as to maximize the contact between the biofilm and the solution.

After 5 seconds, the solution was drained.

Chen Yi looked at the translucent yellowish biofilm that turned black, dried the moisture on the surface, and then measured the weight.

7.81 grams more.

"This speed is a bit surprising."

Chen Yi was a little surprised.

This 7.81 grams is undoubtedly the metal element that this biofilm adsorbs within 5 seconds.

You know, this is just a 21.3 square centimeter biofilm.

If the biofilm is rolled up to increase the contact area per unit time, the adsorption efficiency will increase exponentially.

"Again."

Pour the solution a second time.

Spin likewise to increase contact, drain after 5 seconds.

Chen Yi dried the biofilm and measured the weight.

15.63 grams more.

Subtract the first 7.81 grams.

The weight absorbed this time is 0.01 more.
The third time. The weight increased by 7.8 grams, and the adsorption efficiency was still stable.

The fourth time, still 7.81 grams, the adsorption is still stable.

The fifth time, with an increase of 6.27 grams, the adsorption efficiency dropped by a little more than 20%.

The sixth time, an increase of 5.03 g reached the adsorption limit of the biofilm.

"Unit square centimeter, the adsorption efficiency is 73 milligrams per second, and the total adsorption capacity reaches 2 grams."

"The efficiency of this biofilm is kind of scary."

Chen Yi looked at the weight of 42.6 grams added up to six times, with a hint of shock in his eyes.

This is no longer absorbing metal, this can be regarded as eating metal.

Be aware of the biofilm prior to adsorption.

Its own weight of 21.3 square centimeters is only a little over 6 grams.

After absorbing metal elements, its own weight has increased by more than 8 times, and absorbent paper is not so excessive.

"As for extracting the adsorbed metal, this is simple."

Wearing rubber gloves, Chen Yi took the biofilm weighing about 50 grams and picked up the crucible that had been thrown aside.

After some heating.

Biofilm dissolves and vaporizes.

Only a small ball of black powder rich in various metal elements remained in the crucible.

Chen Yi simply replaced and restored the powder, got it out and put it on an electronic scale to get an accurate weight.

"42.56 grams, it seems part of it is missing."

After recording all the data, Chen Yi began to adjust the properties of the biofilm.

Colorful rays of light bloom.

Cover the remaining small piece of biofilm.

Wait for the light to dissipate.

The biofilm in front of my eyes changed color.

From yellowish to transparent, it becomes silvery white and translucent.

[Item: Metalophilic Biosorption Film]

[Attributes: strength x29.2, alkali metal x109.2, alkaline earth metal x29.5, transition metal x25.1, main group metal x28.4]

[Detecting that a certain attribute exceeds the initial value, do you want to read the information?whether! 】

[Note: This is a biofilm with crazy alkali metal affinity and strong adsorption capacity for other metal elements.

In front of it, no alkali metal ion can escape being adsorbed.

At the same time, it has high strength and can withstand huge pressure without breaking.

With the help of pressure and alkali metal affinity, it can easily crush and split all alkali metal compounds. 】

"Read!"

Without hesitation, Chen Yi chose to read the information.

In an instant, a special biofilm structure and basic principles, as well as corresponding chemical and biological production methods, emerged in my mind.

With the assistance of the system, Chen Yi quickly digested the technical information.

Then through the brain wave induction headband, the production method and technology are uploaded to the supercomputer.

"Xuannv, prepare an alkali metal adsorption film and send it here."

"Your order received."

Xuannv responded.

Very quickly, less than three 10 minutes.

A small piece of biofilm the size of a fingernail was prepared and sent over.

Chen Yi manually divided the biofilm into two halves, and the property interface popped up.

[Item: Alkali Metal—Biosorption Membrane]

[Attributes: Strength x29.2, Lithium x86, Potassium x86, Rubidium x86, Cesium x86, Francium x86]

[Note: This is a biofilm with an insane affinity for alkali metals.]

"Simply the nemesis of alkali metals."

"But at present, I only need lithium element."

Without hesitation, Chen Yi quickly adjusted his attributes.

【Lithium: 86→139】

[Detecting that a certain attribute exceeds the initial value, do you want to read the information?whether! 】

Soon, the properties of lithium changed from 86 to 139, reaching the limit of artificial semipermeable membranes.

After reading the information, Chen Yi sent the relevant technical information to Xuannv as usual.

Next, Chen Yi followed the same method.

The "excessive element biosorption film" was prepared respectively.

Raise the adsorption property of the cobalt element to the highest level, read the technical information, and send it to Xuannv.

There are also bio-absorption films of metal elements contained in lithium batteries such as manganese and nickel, and the reading technology is sent to Xuannv together.

"The biofilm that adsorbs and extracts various elements is done, and the next step is the integrated equipment for lithium battery recycling."

"Discharging, smashing, leaching, and other links of extraction are fine, but this discharge link is a bit difficult for the equipment."

Chen Yi frowned, the discharge step before the lithium battery shattered.

Now on the market, either liquid nitrogen is used to freeze to an extremely low temperature, a puncture short circuit is used to discharge forcibly, or an electrolyte is used to chemically discharge.

"If you want to make an integrated device, the problem of the discharge link must be solved, otherwise the device will be easily scrapped."

"I just read the literature, it seems that there is an eagle sauce, oh, it is the Li-Cycle company of Ma Da."

"A mechanical method is adopted to reduce the size of the battery without discharging, and then use hydrometallurgy to leach the electrode material of the battery."

"Mechanical way to reduce battery size. How does this feel a bit like hydraulics for hydraulics?"

A stalk about the hydraulic machine popped up in Chen Yi's mind.

Since there is a hydraulic press at home, only hydraulic presses are left at home.

"Isn't it, just try it and you'll know."

"If it doesn't work, just waste a virtual learning opportunity, or skip the discharge link and use the discharged battery for crushing and recycling."

"It's just that this requires an upstream enterprise in the industrial chain, and it is also a chemical electrolysis enterprise that pollutes a lot. If you can't do it, don't do it."

Chen Yi found a few lithium batteries that had run out of power on the surface, but still had residual power inside.

Use the machine tool to simply cut a piece of platform that is recessed to help reduce the size of the battery, then take the battery and platform to the hydraulic machine at the base.

Place the platform and battery and adjust the angle.

Chen Yi switched on the hydraulic press.

Bang!

The heavy metal stake began to sink, aiming at the battery and pressing hard for the last time.

Crunch!
But two seconds.

Plenty of smoke and a bad smell, and a faint fire.

Soaring up from the edge of the gap in the platform.

Base smoke sensor activated.

Surrounding exhaust fans rotate to suck the fumes and smells away.

Wait for the short circuit reaction of the battery to end.

Chen Yi put on his mask, took the infrared temperature controller, raised the hydraulic press to check it, and came to several conclusions.

"The volume size is reduced."

"The battery had a short-circuit reaction due to extrusion, and thermal runaway occurred, and the temperature soared to seven or eight hundred degrees Celsius in an instant."

"The high temperature and short circuit triggered a violent reaction, which caused the battery to burn, but did not explode."

"In this way, if there is a special leaching solution, in addition to leaching out the electrode material of the battery."

"It can also increase the difficulty of battery reaction combustion, and at the same time it can cool the battery, and it can also absorb the toxic gas produced by the battery reaction."

"Is it possible to avoid all problems by soaking the battery in such a leaching solution and crushing it?"

Chen Yi's brain opened up, and he quickly thought of a way to solve the problem of battery short-circuit discharge.

After all, lithium batteries are used up and then recycled.

Even if there is still some unusable power inside, this little power can't make too much trouble.

In this way, the temperature is lowered by wet method, and at the same time, the difficulty of battery combustion reaction is increased, which is very feasible.

Combustion is suppressed.

The so-called battery explosion will naturally not occur.

Do it when you think of it.

Chen Yi passed on his thoughts to Xuannv.

For the study of chemistry and biology.

Xuannv, who is currently nestled in the laboratory every day, is the leader.

hum!
The supercomputer outside buzzed for a while.

Ten minutes passed.

The four chemical formulas were passed back by Xuannv.

It means that these four chemical formulas are respectively applicable to the common ternary lithium, lithium iron phosphate, lithium cobalt oxide, and Yifei’s carbon silicon lithium.

Follow the directions for the chemical formula.

It took Chen Yi more than two hours to carefully prepare the three solutions of ternary lithium, lithium iron phosphate, and lithium cobaltate, and start the piling test of the hydraulic press again.

A special spray platform is designed.

The special leaching solution is poured in, so that the battery can be immersed in it, and at the same time, it is continuously circulated and sprayed through the circulation system.

Chen Yi first applied the lithium cobalt oxide solution.

Bang!

The pile head of the hydraulic press sank and pile driving began.

after a few seconds.

The heavy pile head is lowered onto the lithium cobalt oxide battery submerged in the solution.

The spray system was then turned on, continuously spraying the solution to the battery and the pile head belt.

Gudu, Gudu.

The hydraulic press drives the pile to the end.

The solution produced two bubbles.

Imagine smoke, sparks, burning explosions, nothing happened.

Only the originally clear solution began to turn black and cloudy.

It seems that a large amount of battery material has been leached and melted into it.

"Perfect, sure enough, the mechanical piling extrusion must choose the wet method."

"Dry piling extrusion, the risk is too high, it is easy to get injured."

It is determined that there is no problem with wet piling extrusion crushing.

It took five days for Chen Yi to improve after many experiments.

Finally, a prototype of lithium battery integrated recycling equipment was designed.

This is a kind of rolling extrusion type, a large peanut oiling machine.

A feeding port, behind the feeding port are two high-torque, mutual-rolling extrusion steel wheels.

The battery is squeezed by the steel wheel, and the structure is destroyed.

The next step is repeated grinding to ensure that the battery is crushed to the smallest particles.

The crushed battery powder is sent to the subsequent leaching area.

After a certain period of solution leaching, the valuable electrode materials contained in the battery powder will be leached out, and then adsorbed and extracted through the biofilm.

Besides.

The equipment is also designed with a wet suppression circulation system.

Through the pipeline, the filtered leaching solution is extracted and transported to the extrusion area of ​​the steel wheel.

Inhibit the reaction and combustion of the battery extrusion short circuit, and at the same time reduce the temperature.

Ensure that the process from steel wheel extrusion to subsequent grinding and crushing is carried out in a humid environment without risk of reaction.

The whole set of equipment, the only consumable is the leaching solution.

However, because the leached electrode material will be continuously absorbed and extracted by the biofilm, the only consumed leaching solution can also be recycled in the equipment.

According to Chen Yi's calculations.

The leaching solution can be circulated 700 to 800 times as a whole, after which the leaching performance will drop significantly.

From 99.9 percent leaching, down to 90 percent, 80 percent.
Replacement based on performance degradation.

An average of 1 kg of leaching solution can extract more than 1.3 kg of lithium.

In addition to carbon-silicon batteries, other different battery types can handle batteries ranging from 100 to 280 kg.

Calculated on the basis of 50 kg of leaching liquid for one piece of equipment.

This one piece of equipment can handle more than ten tons of power batteries, which greatly improves the utilization efficiency of the leaching solution and reduces the difficulty of pollution treatment.

"We're still short of the last biofilm."

Through machine tools and printers, a prototype is produced.

It took several hours for Chen Yi to take a roll, and Xuannv produced the lithium metal biosorption membrane, and cut off a part.

[Item: Lithium Element - Absolute Biosorption Membrane]

[Attributes: Strength x29.2, Lithium x139]

[Note: This is a kind of bio-adsorption film that has an absolute affinity with lithium metal, which makes people crazy. None of the lithium elements and isotopes of any liquid can escape its adsorption. 】

"Absolute adsorption. This is simply the best equipment for doomsday technology."

Chen Yi took out a shell with a water inlet and outlet, which was similar to a water purifier filter element, rolled the adsorption membrane into a roll and stuffed it in, and then installed it tightly.

Test it to make sure the water in and out is normal.

Chen Yi stuffed it into the lithium battery recovery equipment, one of the several adsorption extraction ports reserved.

Then take the cobalt metal biosorption film, and also subtract a part.

[Item: Cobalt Element - Absolute Biological Adsorption Membrane]

[Attributes: Strength x29.2, Cobalt x139]

【Note: This is an absolute affinity with cobalt metal.】

"With this cobalt biosorption film, the so-called cobalt bomb deterrent on the other side seems to be bankrupt and scrapped."

Looking at the same abnormal properties of this cobalt adsorption film.

Chen Yi was stunned for a moment, and suddenly thought of a funny thing in his heart.

With this, even if the opponent shoots cobalt bombs crazily.

You only need to get some of these cobalt biosorption membranes in the water source area and living area.

After a period of adsorption, it will be recycled and destroyed.

The radiation threat of this cobalt bomb is self-defeating.

"When you have time, make an experimental video and send it to the other side."

Chen Yi smiled and stuffed the cobalt biofilm into the other extraction ports of the equipment, followed by the adsorption films of nickel, manganese and other elements.

All the adsorption membranes are installed.

An interface appeared in front of my eyes.

[Item: Perfect Grade - Fully Automatic Lithium Battery Recycling Equipment]

[Attributes: Strength x29.2, Lithium x139, Cobalt x139, Nickel x139, Manganese x139]

[Note: This is a perfect lithium battery recycling device beyond the imagination of the world. No element of a lithium battery can withstand its recycling deprivation.

As a perfect level of equipment, any random core component inside can bring a million points of shock to the world]
