Technology Tycoon: From Real Estate Tycoon To Technology Overlord

This time when he came to the BYAT laboratory, Masca's most important purpose was to watch the destructive testing. As for capacity and durability, he didn't care much.

After all, the new lithium material has been tested in high-energy laboratories, and the results are indeed that the energy density is much higher than that of lithium.

Seeing that Maska was making three demands, Wang Fu had no choice but to take Maska to the off-site testing site.

"President Ma, let's test this block directly and see how it works!"

Wang Fu asked, pointing to the battery gift package that Maska's assistant had just brought over.

Maska nodded directly in agreement with what Wang Fu said and pointed directly at the two batteries in the battery gift pack.

"Okay, after testing the block-shaped one, there is no need to test the other model and the remaining small batteries after testing the cylindrical one."

With Maska's consent, Wang Fu immediately arranged for laboratory employees to start preparations.

“Test the capacity first, and then conduct a destructive test directly after it is full.

After receiving Wang Fu's instructions, a middle-level manager of the laboratory immediately took 25 batteries of two specifications and came to the test area, and ordered to the staff inside.

"clear!"

The three testers immediately took the battery and got into action.

They first fully charged the battery, and then began to record the discharge capacity.

This step is mainly to verify whether the battery is valid, otherwise if you take a bad battery, there will be no power.

After all, if the battery has no power, destructive testing is of no reference value at all. Current explosions and fires are caused by the lithium battery being short-circuited and instantly generating a large amount of energy, which directly leads to explosions and fires.

After more than 40 minutes of preparation, the staff conducted two rounds of charge and discharge tests to verify that both were good.

They just started destructive testing in earnest.

"President, President Ma, the current test is a puncture test."

Peeking through the glass window, the research staff pointed to the opening of the equipment with a steel needle of several millimeters outside and explained.

Maska, who was still sitting and chatting with Wang Fu, heard the interpreter say that the test would start soon. He immediately cheered up and looked towards the test equipment.

The first to undergo destructive testing was the block battery. Look at the fully charged block battery placed horizontally under the steel needle.

As soon as the employee started the equipment, the steel needle slowly penetrated into the battery.

Normally, if it is a fast lithium battery, whether it is a lithium iron phosphate battery or a ternary lithium battery, when it is fully charged, white smoke will instantly emit, then sparks will fly, and then there will definitely be a fire and explosion.

At this moment, Maska stared at the battery without blinking.

One second, three seconds, five seconds, ten seconds.

Quiet! It’s surprisingly quiet both indoors and outdoors.

In the room, the two bosses stopped breathing and watched the battery reaction. The remaining employees did not dare to make a sound, so it was very quiet.

On the outdoor test equipment, although the battery was penetrated by a steel needle, there was no reaction at all after ten seconds.

Just as the faces of Maska and Wang Fu became more and more shocked.

The battery that had been penetrated by the steel needle finally responded, and a lot of white foam finally began to emerge from the gap in the wound.

This should be when the positive and negative materials inside the battery come into contact and then undergo a chemical reaction.

One minute, two minutes, five minutes.

After a full five minutes, except for white foam coming out of the battery, there was no bulging, let alone sparks or explosions.

The staff watched the clock arrive, immediately lifted the steel pin of the equipment, and then pulled the battery out of it.

"The next step is to conduct a destructive test, which will destroy the entire battery structure, simulating a very serious car accident that causes the battery pack to be damaged!"

The tester took out another battery, put it on another device and explained to the people in the room.

After saying that, after putting the battery in place, he pressed the switch without hesitation.

In an instant, the entire device started running, and the entire battery was immediately destroyed.

In less than a minute, the entire battery casing was cracked, and all the materials inside were splashed everywhere.

This time the effect was the same as last time, except for a little chemical reaction when the two substances came into contact, white foam continued to bubble up, and not even a spark appeared.

Finally, after the battery completely fell apart, people present suddenly saw that there was a PCB board inside the battery.

You must know that at present, whether it is Ning's Group, Tesla or Panasonic, the batteries of world giants such as LG only have single positive and negative materials.

There is no so-called circuit board at all. After all, the protective board is currently only added when the battery pack is integrated.

Maska looked at the PCB board that fell to the ground, and thoughts flashed through his mind.

In the end, he ignored the fact that this was Biati's laboratory and shouted directly:

"Hmph! Just short-circuit that battery for me and see if there will be a short-circuit phenomenon."

After hearing this, the researcher first turned to look at Wang Fu. When Wang Fu nodded in agreement, he turned to the staff and signaled to obey the other party's instructions.

Since the phone only had two fully charged cylindrical batteries left, the staff could only pick up one of them and quickly connect the wires.

After connecting it, the staff member picked up the wire and looked inside to indicate that he wanted to start.

Then directly pick up the two wires and short them together.

puff!!!

At the moment of short circuit, a spark bursts out from the contact point between the two wires.

It's just that the spark only lasts for a moment, and then there is no more movement from the battery.

Originally, a normal short circuit would generate heat directly, but at this time, the shorted wire had no reaction.

Even the thermal imaging camera that has been pointed at the battery 347 shows that the battery temperature has not changed at all.

The staff was determined to test it several times.

Sure enough, when I removed the connecting wires and shorted them several times before, sparks would burst out, indicating a real short circuit.

But it only lasts for a moment each time. What people didn't expect was that there was no response after the fifth short circuit.

When the employee saw this, he guessed that he should enter the protection mode. After giving up the short circuit for a minute, the short circuit finally responded again.

"That PCB should have a built-in protection board. Why don't you dismantle the protection board and test it?"

The researcher standing aside saw this and spoke his mind.

After hearing this, Wang Fu thought for a while and nodded directly in agreement with the other party's idea:

"Okay, let them disassemble the battery, first remove the protective plate and test it directly by short-circuiting the battery cells.

With Wang Fu's consent, the researcher immediately walked out of the viewing room and asked the test employees to start disassembling the batteries and taking off the panels.

"President Wang, judging from the current data.

At present, both ternary lithium batteries and lithium iron nitrate batteries are lagging far behind.

Especially when it comes to safety, there is no comparison between the two!!"

While the employees were dismantling the batteries, Maska said to Wang Fu with a melancholy look on his face.

Although there are still several items that have not been tested, just after seeing the puncture test and destructive test just now, Muska has already sentenced the original battery to death in his heart. .
