I am farming in the real world.

Chapter 229: It’s really off the charts!
It's not unreasonable for Chang Yuhao to think this way.

After all, when it comes to mass-produced solid-state batteries, all leading battery manufacturers are making every effort to develop and launch projects.

Compared with today's traditional power batteries such as ternary lithium and lithium iron phosphate that use liquid, gel and polymer as mainstream electrolytes.

The solid-state electrolytes used in solid-state batteries not only have higher energy density, but also have stability and safety performance that are several times or even dozens of times better than traditional power batteries.

This is like a bucket filled with water which tends to spill when shaken.

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

However, such awesome solid-state batteries are still in the state of "only heard but not seen" in the commercial field.

Major manufacturers such as BYD, CATL, and Chery Kunpeng have already produced solid-state batteries in the laboratory, and have even iterated N versions.

However, none of them have truly been put into mass production. Even among those that have been released into the market, only Chery Kunpeng has held a press conference to announce that it will be officially put into use in 2027.

At this time, Chen Jue suddenly took out a mature solid-state battery sample, which easily made Chang Yuhao and his employees imagine a lot.

Because Magic Cube Group has never been involved in the battery project before!
It wasn't stolen through industrial espionage, so it couldn't have appeared out of thin air, right?
Chen Jue did not explain in detail the origin of this graphene lithium battery.

After giving the other party a look to "move faster", Chang Yuhao smiled for a while and began to use a multimeter to carefully check the black "brick battery" that looked a bit like a smartphone.

He just touched the battery casing with the two black and red test leads of the multimeter, and was shocked by the voltage data jumping wildly on the LCD screen!
"Fuck!"

"999 volts, it's exploded???"

Chang Yuhao's hands trembled and he almost shrank back.

Because the upper limit of measurement of traditional digital multimeter is just 1000V.

He used two test leads to test it, in order to confirm the direction of the positive and negative electrodes of this "brick battery" of unknown origin, so that he could stick two electrode sheets on it before the subsequent on-machine test.

Unexpectedly, the upper limit of the multimeter's display was exceeded as soon as the test started.

"Wait...how come there's no arcing at such a high voltage?"

Chang Yuhao was confused.

With doubt, he adjusted the multimeter to the current range and tentatively touched the previous position with two test leads.

With two "beep~" sounds, the multimeter that had originally returned to zero showed data again.

The current displayed on the LCD screen instantly increased by more than 500 amperes.

Such a horrible output current frightened Chang Yuhao so much that he shuddered all over!
Because this current data was no longer a matter of size, but it exceeded the battery performance comparison data he had learned, and completely shattered his worldview.

"More than 500!"

"This is not even the normal current output of the BMS (battery module and battery management system)?"

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

The power battery module of traditional new energy vehicles, with the cooperation of the battery management system, can burst out a current output of more than 100 to 200 amperes in an instant after the accelerator... no, the accelerator is stepped on to the bottom.

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 do not even have an output power of 100 amps.

For example, the power battery on the old man’s bike cannot increase its speed even if you stand up and pedal.

The black-tech battery that Chen Jue brought produced over 500 amps without even a BMS. If a BMS was installed and the peak output power was adjusted several times higher through software, even Chang Yuhao didn't dare to think about the result!
What made Chang Yuhao feel even more incredible was that even though this thing produced such a high current, there was still no sign of arcing.

What a terrifying stability this is!
Countless doubts flashed through Chang Yuhao's mind.

Because in his eyes, this little black brick is full of black technology that he cannot understand!

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

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

Once again, I took the test leads and randomly touched the black brick battery case. Every time I connected the battery, the multimeter worked normally.

There was no sign of a short circuit.

"This, this, this...what is the principle behind this?"

This breaks the discharge performance of traditional battery science and makes Chang Yuhao unable to do anything!
Lao Cai wanted to continue explaining: "This is the normal discharge characteristic of 100% lithium and graphene coating. According to the existing theoretical knowledge of mankind..."

Chen Jue, who was standing by, realized something was wrong and immediately coughed twice, signaling it to speak a few human words.

Seeing that the boss was kicking his calf, Lao Cai stopped showing off and began to explain in a different way: "To put it simply, it is an electrodeless high-voltage DC external output design made with cutting-edge materials, which reduces the resistance loss caused by traditional graphite electrodes and theoretically maximizes the number of cycle discharges and current output power."

"???"

Chang Yuhao had a look of black question marks on his face.

He always felt that the battery expert brought by the chairman was a little mysterious and the theories he talked about were more profound than the courses he listened to in college.

But now that we know that this thing can ignore the electrodes, we can use it directly by connecting it to electricity.

Chang Yuhao's operations began to become bolder.

He opened the largest floor-standing battery tester in the deepest part of the laboratory.

I simply connected this black-tech battery to various circuits and put it in, intending to try a more violent extreme test.

As the device started up, various data indicators began to jump wildly on the large LCD screen.

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

Just looking at the J-shaped upward trend, Chang Yuhao couldn't help but open his mouth in an O shape: "Wow! The battery energy density is estimated to be 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 be easily over 3000 kilometers?"

"And the maximum charging power it can withstand is 2221KW? The internal structure is stable under 2000V voltage, and there is no evidence of melting or breakdown of the battery cells."

"The battery temperature... the temperature only rose by 1 degree Celsius?"

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

Until I heard the chairman and the big-nosed expert behind me discussing in a low voice whether they should improve and optimize the process of this graphene lithium battery and enhance its performance.

Chang Yuhao finally came to his senses and turned around with a sad face: "Chairman! Please discuss it with the materials business, don't change it!"

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