Chapter 37

To sell weapons to individuals, one must first reduce the fees for hyperspace transmission to a very cheap level.

As for using ordinary express delivery,

Lin Yi had never even considered it; no matter how careful he was, this method would inevitably leave traces.

It might succeed once or twice, but over time,

he would definitely be exposed.

After all, the intelligence agencies of various countries do not just eat without working.

Speaking of which, Lin Yi had once watched a Hollywood film from the Ugly Country starring Nicolas Cage, titled "Lord of War."

The arms dealer he portrayed once said:

"There are 550 million weapons in the world, meaning one for every thirteen people; what I do is find ways to sell weapons to the remaining twelve!"

And this was Lin Yi's future goal.

However, since the number of customer orders was still low,

he temporarily set aside the affairs of the arms shop.

After nearly a month of research and development,

inside the factory of Fengyi Technology Company located at the Songjiang Entrepreneurship Center,

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

The two teams led by Zhao Zhao Xuebin and Wen Xiang

had successively overcome the challenges regarding the cathode of the nickel-lithium cobalt-free battery, the solid-state electrolyte, and the carbon-silicon anode.

Yet, this was merely the first step.

Next, the two teams would continue researching battery technologies based on lithium manganese iron phosphate and lithium-rich manganese base.

But even so,

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

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

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

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

This meant that, under equal volume conditions,

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

What concept did this represent?

Taking current smartphones as an example,

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

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

In other words, if using the nickel-lithium cobalt-free battery,

under the same mass, the new battery's capacity would be more than three times greater; the iPhone 6S battery capacity was 1810mAh,

while the new battery, under the same mass, would exceed 5000mAh.

This was still under identical mass conditions.

If volume was taken into account, since the nickel-lithium cobalt-free battery

removed the cobalt element, which had a high mass density,

using nickel and lithium as the primary materials meant that, under equal mass, the new battery would be thinner and smaller in volume.

It was projected that the new 5000mAh battery would be only half the thickness of the iPhone 6S's 1810mAh battery.

Regarding cost, because the cobalt element, which had the most unstable supply channel and was the most expensive, was removed,

the cost of the new battery

meant that a single 5000mAh new battery was not even half the price of an 1810mAh lithium cobalt oxide battery.

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

Although everyone in the group had eyes rimmed with red bloodshot veins from

researching day and night during this period,

their spirits were highly excited.

Dr. Zhao continued speaking:

"Besides what was mentioned above, thanks to Dr. Wen's team's research on the solid-state electrolyte, the safety of this new battery can be said to be the best among all lithium batteries!"

Saying this, Dr. Zhao performed the most intuitive test right in front of Lin Yi.

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

If this were an old-style liquid electrolyte battery, once the internal temperature of the battery reached a critical point,

the battery pack would explode and spontaneously combust.

However, under the calcination of flames measuring 600 degrees by a temperature gun, the new battery merely emitted rolling black smoke,

yet it did not catch fire, let alone explode.

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

at this time, the properties of the electrolyte will change, transforming the solid-state electrolyte, which originally served as an ion carrier to conduct ions, into

an obstacle that blocks lithium ions from moving between the positive and negative electrodes, thereby achieving a power-off protective effect!"

"It can be said that, compared to ordinary lithium batteries, the new solid-state electrolyte not only achieves a multiple-fold increase in capacity but also

holds epoch-making significance in terms of safety!"

"In addition, the ionic conductivity of the solid-state electrolyte in the new battery reaches as high as 3.42mS/cm,

which means the new battery possesses much faster charging and discharging capabilities than ordinary lithium-ion batteries,

truly achieving 'charge for five minutes, use for a whole day'!"

Then Dr. Zhao continued:

"After subjecting the new battery to 2,000 charge-discharge cycles, our tests show battery degradation of less than 3%, which is far lower than any battery product currently on the market!"

Hearing his account, Lin Yi felt extremely excited inside.

After all, unlike the arms business that could not be exposed, this battery before him would be his first flagship product for his overt career.

It held a different significance for him.

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

Although this was a reward given by the system, without Dr. Zhao and the others working day and night on their research, relying solely on Lin Yi,

it would have been very difficult to turn the technology into a tangible result.

For this, Lin Yi was deeply grateful to every member of the Fengyi Technology research team.

However, as someone about to step into the battery industry, he asked with meticulous care:

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

According to existing data, lithium-ion output performance suffers greatly when temperatures drop below 0°C.

Below -20°C, battery performance deteriorates significantly; at -40°C, the battery can only deliver 30% or even less of its rated capacity.

This is mainly because, under low-temperature conditions, the electronic conductivity within the battery is low and lithium-ion diffusion is poor; simultaneously, at low temperatures,

the electrolyte's conductivity declines, increasing internal resistance, causing polarization, and impairing battery performance.

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

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

Furthermore, under low-temperature conditions, the solid-state electrolyte is affected far less than liquid electrolytes... We conducted corresponding experiments:

between 0°C and -10°C, the new battery is almost unaffected; between -10°C and -20°C, its output performance drops by only 5%.

Only under extreme conditions, specifically when temperatures fall below -40°C, does performance plummet to 80%.

But even so, our battery's performance under identical conditions remains far superior to other lithium batteries...!"

As soon as Dr. Zhao finished speaking, Lin Yi immediately began to applaud.

"Clap, clap, clap...!" For a moment, vigorous applause echoed throughout the entire laboratory.
