I am farming in the real world

Chapter 229: True · Off the Charts!

Chang Yuhao's secret thoughts weren't without reason.

After all, when it came to mass-produced solid-state batteries, all the leading battery manufacturers were putting in their best efforts in research and development.

Compared to current ternary lithium and lithium iron phosphate batteries, which primarily use liquid, gel, or polymer electrolytes, solid-state batteries use solid electrolytes, which not only have higher energy density but also offer several times, even dozens of times, better stability and safety performance than traditional power batteries.

It's like a bucket filled with water, which can easily spill when shaken.

But if you replace the water with a solid block of ice, you don't have to worry about leakage.

However, such impressive solid-state batteries are still in a state of 'heard of but not seen' in the commercial field.

BYD, CATL, Chery Kunpeng, and other major manufacturers have already produced solid-state batteries in the lab, even iterating through N versions.

But none have truly entered mass production; even those that have trickled into the market, like Chery Kunpeng announcing its official use in 2027 at a press conference, are rare.

Therefore, Chen Jue suddenly taking out a mature solid-state battery sample easily made Chang Yuhao and his subordinates start to speculate.

Because Magic Cube Group had never ventured into battery projects before!

If it wasn't stolen through commercial espionage, could it have just appeared out of thin air?

Chen Jue didn't explain much about the origin of this graphene lithium battery.

After giving the other party a 'hurry up' look, Chang Yuhao put on a serious face and began to carefully examine this dark, brick-like 'brick battery' with a multimeter.

But as soon as he touched the battery casing with the two black and red probes of the multimeter, the wildly jumping voltage data on the LCD screen startled him!

"Damn it!"

"999 volts, directly off the charts????"

Chang Yuhao's hand trembled, and he almost recoiled.

Because the measurement limit of traditional digital multimeters is only 1000V.

He used the two probes to test, intending to confirm the positive and negative electrode directions of this unknown 'brick battery' so that he could attach two electrode sheets before the subsequent on-machine testing.

Unexpectedly, as soon as he tested it, the display limit of the multimeter was exceeded.

"Wait a minute… how can such a high voltage not spark?"

Chang Yuhao was dumbfounded.

With a puzzled expression, he adjusted the multimeter to the current range and tentatively touched the previous position again with the two probes.

"Beep beep~" Twice, the multimeter, which had returned to zero, jumped up again.

The current displayed on the LCD screen instantly magnified to more than 500 amps.

Such a terrifying output current shocked Chang Yuhao again!

Because this current data was no longer a question of being large or small, but exceeded the battery performance comparison data he had learned, completely shattering his worldview.

"More than 500 amps!"

"This is the normal current output without even using a BMS (Battery Module and Battery Management System)?"

"Is the performance of solid-state batteries so terrifying? I remember that the peak data just released by Chery Kunpeng was less than half of this battery's!" Chang Yuhao took a deep breath.

Under the coordination of the battery management system, the power battery modules of traditional new energy vehicles can burst out 100~200+ amps of current output in an instant when the accelerator... no, the electric pedal is pressed to the end.

Of course, this is still the output performance of mid-to-high-end power batteries on the market.

Some batteries installed in low-end entry-level models can't even reach 100 amps of output power.

For example, the power batteries on those 'old man's joy' vehicles can't even reach a decent speed when you stand up and pedal.

This black technology battery brought by Chen Jue produced more than 500 amps without even using a BMS.

If a BMS was added and the peak output power was increased several times through software, Chang Yuhao didn't even dare to think about the result!

What made Chang Yuhao even more incredible was that even though this thing was outputting such a high current, he still didn't see any arcing phenomena.

How terrifying is its stability?

Countless doubts flashed through Chang Yuhao's mind.

Because in his eyes, this dark little brick was full of black technologies that he couldn't understand!

At this time, Lao Cai, who came to the battery factory with Chen Jue, said, "Its surface is a graphene coating and does not have a traditional electrode structure."

Chang Yuhao came back to his senses: "No positive or negative electrodes?"

He took the probes again and randomly touched the dark little brick battery casing; each time he connected the circuit, the multimeter could work and display normally.

Not a single sign of a short circuit appeared.

"This, this, this… What is the principle behind this?"

This discharge performance, which broke the traditional battery science, directly stumped Chang Yuhao!

Lao Cai wanted to continue to explain: "This is the normal discharge characteristic after 100% elemental lithium and graphene coating are combined. With the current theoretical knowledge of mankind…"

Chen Jue, realizing that something was wrong, immediately coughed twice, signaling him to speak human language.

Seeing his boss kicking his calf, Lao Cai stopped showing off and began to explain in a different way: "Simply put, it's a non-electrode high-voltage DC external discharge design that uses cutting-edge materials, reducing the resistance loss caused by traditional graphite electrodes and theoretically maximizing the number of cycle discharges and the current output power."

"???"

Chang Yuhao showed a black question mark face.

He always felt that the battery expert brought by the chairman was a bit profound, and the theory he spoke was even more esoteric than the courses he had listened to in university.

However, since he knew that this thing could ignore electrodes and be directly connected for use, Chang Yuhao's operation became bolder.

He opened the deepest and largest floor-standing battery tester in the lab.

He directly put this black technology battery in with various circuits, intending to try some more violent extreme testing.

With the start of the equipment, various data indicators began to jump wildly on the large LCD screen.

Multiple data, including current, voltage, capacity, internal resistance, charging, discharge temperature, battery cycle life, etc., began to be outlined on the screen in the form of icon XY axis curves.

Just looking at the J-shaped curve that was constantly rising, Chang Yuhao couldn't help but open his mouth into an O-shape: "Holy crap! Estimated battery energy density of 862wh/kg????"

"This… What the hell is this capacity performance!"

"If this thing is installed on NIO's ES6 model, wouldn't the pure electric range easily reach more than 3000 kilometers?"

"And the maximum bearable charging power is 2221KW? The internal structure is stable under 2000V voltage, and no cell melting or breakdown is seen."

"Battery temperature… The temperature actually only increased by 1 degree Celsius?"

When the entire set of extreme tests was completed, Chang Yuhao froze in place, staring at the flattened curve on the big screen.

Until he heard the chairman and the big-nosed expert behind him discussing in a low voice whether to improve and optimize the process of this graphene lithium battery to further improve its performance.

Chang Yuhao woke up, turned his head with a mournful face, and said: "Chairman! Please discuss with Engineer Cai, don't change it!"

"If you change it again, domestic competitors will go bankrupt!"
