Chapter 70: The starting point of the career! The explosive performance of the new battery!

However, because the number of orders was still small,

he temporarily put the arms store matter aside.

After nearly a month of research,

inside the factory of Fengyi Tech Company at the Songjiang Startup Center,

the first solid-state super battery was finally researched out of the laboratory.

The two teams of Zhao Xuebin and Wen Xiang

had successively conquered the positive electrode of the nickel-lithium cobalt-free battery, the solid electrolyte, and the carbon-silicon negative electrode.

And this was just the first step.

Next, the two teams would continue to research lithium manganese iron phosphate and lithium-rich manganese-based battery technology.

But even so,

when the first solid-state super battery was manufactured and tested,

the results were shocking. The energy density of this new battery reached 488Wh/kg,

compared to the 200Wh/kg and 110Wh/kg of ordinary ternary lithium batteries and lithium iron phosphate batteries.

The density of the new material battery was more than twice that of ternary lithium batteries and nearly 5 times that of lithium iron phosphate batteries.

This meant that under the same volume,

the capacity of the nickel-lithium cobalt-free battery was more than twice that of ternary lithium batteries and nearly 5 times that of lithium iron phosphate batteries.

What kind of concept was this?

On current smartphones,

the latest iPhone 6S was equipped with a second-generation lithium cobalt oxide battery,

with a voltage of 4.2V and a capacity close to 155mAh/g.

That is to say, if they used the nickel-lithium cobalt-free battery,

at the same mass, the capacity of the new battery would be more than three times higher; the iPhone 6S battery capacity was 1810mAh,

while the new battery at the same mass would exceed 5000mAh.

This was still at the same mass.

If one counted the volume, because the nickel-lithium cobalt-free battery

removed the cobalt element with a larger mass density,

and used nickel-lithium as the main material, this meant that at the same mass, the new battery was thinner and smaller in volume.

According to estimates, a 5000mAh new battery was only half the thickness of the iPhone 6S's 1810mAh battery.

And in terms of cost, because it removed the cobalt element, which had the most unstable and expensive acquisition channel,

the cost of the new battery,

a 5000mAh new battery was not even half the cost of an 1810mAh lithium cobalt oxide battery.

At this time, Dr. Zhao was explaining the technical advantages of the new battery in front of Lin Yi.

Although every person in this group had red bloodshot eyes,

having researched day and night for this period,

their spirits were all very high.

Dr. Zhao continued:

"Besides what I said above, thanks to the research of Dr. Wen's team on solid electrolytes, the safety of the new battery can be said to be the best among all lithium batteries!"

As he spoke, Dr. Zhao performed the most intuitive test in front of Lin Yi.

He threw a high-voltage new battery directly into a fire.

If this were an old-fashioned electrolyte battery, as the internal temperature of the battery reached a critical point,

the battery pack would explode and spontaneously combust.

However, under the calcination of a 600-degree flame measured by a temperature gun, the new battery only emitted billowing black smoke,

but it did not burn, nor did it explode.

"This is because once this new type of solid electrolyte is heated to a certain critical point, it will dissolve.

At this time, the nature of the electrolyte will change, making the solid electrolyte, which originally acted as an ion carrier to conduct ions, become

a blocker that prevents lithium particles from moving between the positive and negative electrodes, thereby playing a power-off protection role!"

"It can be said that compared to ordinary lithium batteries, the new solid electrolyte not only has a multiple increase in capacity,

but also has epoch-making significance in terms of safety!"

"Besides this, the conductivity of the new battery's solid electrolyte is as high as 3.42mS/cm,

which means the new battery has faster charging and discharging technology than ordinary lithium-ion batteries,

truly achieving charging for 5 minutes and using it for a whole day!"

He heard Dr. Zhao continue:

"After our 2000 charge-discharge tests on the new battery, the battery loss did not exceed 3%, which is far lower than all battery products on the market now!"

Hearing his description, Lin Yi was very excited inside.

After all, unlike the arms business that could not be exposed, this battery in front of him would be the first flagship product of his public career.

This had a different meaning for him.

Now the first product was so excellent, surpassing the performance of all lithium batteries on the market.

Although this was a reward given by the system, if it weren't for the day-and-night research of Dr. Zhao and others, relying only on Lin Yi alone,

it would be difficult to turn the technology into results.

To this, Lin Yi was still very grateful to everyone in the Fengyi Tech research team.

However, as someone about to enter the battery industry, he asked with a pursuit of excellence:

"How does the battery perform under low-temperature conditions?"

According to existing data, when lithium ions are below 0°C, the output performance is greatly affected.

At low temperatures below -20°C, the battery's performance significantly deteriorates, and at -40°C, the battery can only release 30% or even less of its rated capacity.

This is mainly because under low-temperature conditions, the electronic conductivity inside the battery is low, and lithium-ion diffusion is poor. At the same time, at low temperatures,

the electrolyte conductivity is poor, which increases the internal resistance of the battery, causing polarization and affecting battery performance.

Hearing this, Dr. Zhao, who was wearing black-rimmed glasses, smiled and said:

"Hmm, I was just about to tell you this, Boss. Because we used a solid electrolyte, the conductivity of our new battery is far higher than that of lithium batteries on the market,

and under low-temperature conditions, the solid electrolyte is far less affected than the liquid electrolyte... We did corresponding experiments.

At 0 to minus 10 degrees, the new battery is almost unaffected, and at minus 10 to minus 20 degrees, the new battery's output performance decreases by 5%.

Only under extreme conditions, that is, when the temperature is below minus 40 degrees, will the performance drop sharply to 80%,

but even so, the performance of our battery in the same environment is far better than other lithium batteries....!"

When Dr. Zhao's voice fell, Lin Yi immediately started clapping.

"Clap clap clap...!" For a time, intense applause rang out throughout the entire research room.
