58: Chapter 58 Challenging the Limits of Physics!

One month later.

The workshop of the High-Precision High-Tech Department.

This place had become the most restricted core area of Star Technology; even Old Zhang could only enter with Chen Xu's permission.

Chen Shiyi walked up to Chen Xu, holding an anti-static silver sealed box in both hands.

The box opened.

A silver-gray metal block lay quietly in the precisely cut foam recess.

This was the super battery.

Its appearance was plain and unadorned, even bearing rough traces of manual polishing, and the casing was not a smooth mirror finish but had the texture of an industrial blank.

Old Zhang stretched his neck to stare at the object in the box, his brow furrowed deep.

"This is it?"

"It looks no different from the power bank cells sold at roadside stalls."

Chen Xu picked it up.

It felt slightly heavy in his hand, with a hard, cold texture.

"Fifty units, all completed. This is one of them," Chen Shiyi reported.

"Test it."

---

"First test, extreme temperature difference."

Chen Shiyi pushed over two pieces of equipment.

An industrial deep-freeze cabinet capable of dropping the temperature to negative eighty degrees.

A precision baking oven capable of reaching temperatures up to three hundred degrees.

Old Zhang brought over a ternary lithium battery from Dening Era from the material rack, which he had specifically asked someone to buy from the market for comparison.

"Mr. Chen, you might not know this."

Old Zhang couldn't help but speak up: "Normal lithium batteries lose thirty percent of their performance at negative ten degrees, and are basically useless at negative twenty degrees."

"As for negative fifty degrees..."

He shook his head: "The electrolyte would freeze solid, and the battery would be scrapped."

"High temperatures are even more dangerous. There's a risk of thermal runaway above sixty degrees, and at one hundred degrees..."

He swallowed hard: "It will explode."

Chen Xu didn't respond.

Chen Shiyi had already put on heat-resistant gloves and began the operation.

One super battery was placed into the deep-freeze cabinet.

Another was placed into the baking oven set to one hundred degrees.

For comparison, the Dening Era ternary lithium battery was treated the same way.

The timer started ticking.

Old Zhang's gaze shifted back and forth between the two cabinets, and sweat began to bead on his forehead.

He had worked in battery-related fields for thirty years and knew exactly what such extreme tests meant.

Thirty minutes later.

Chen Shiyi opened the deep-freeze cabinet.

White cold air surged out, instantly condensing into fog in the air.

The casing of the Dening Era battery was covered in white frost.

Chen Shiyi picked it out with tweezers, placed it on the test bench, and connected a multimeter.

The screen displayed: 0.00 V.

The voltage had dropped to zero.

It was completely frozen dead.

Old Zhang nodded; this was normal and completely within his expectations.

Next, Chen Shiyi opened the baking oven.

A wave of heat rushed out.

The ternary lithium battery that had undergone the high-temperature roasting was in worse condition—the blue casing was visibly bulging, the seams had been forced open by internal gases, and a pungent chemical odor filled the air.

Old Zhang instinctively stepped back half a step.

Such a bulging battery could short-circuit and catch fire at any moment!

Chen Shiyi took out the super battery.

Their appearance had hardly changed.

The low-temperature battery was connected to the multimeter.

Beep—

The screen lit up, and the numbers stabilized: 3Ah.

Performance, completely normal!

Chen Shiyi connected the high-temperature battery to the tester as well.

The result was exactly the same!

"This..."

Old Zhang rushed forward, grabbed the multimeter, and re-tested the probe connection.

The instrument wasn't broken.

The data was real.

He raised his head, unable to speak.

---

"Second test, extreme fast charging."

Chen Shiyi pushed over a menacingly designed modified charging station, with an output power three times that of the fastest charging station on the market.

The wires were as thick as an adult's thumb.

A thermal imager was also set up on the side to monitor temperature changes in real-time.

Seeing this equipment, Old Zhang's expression changed instantly.

"Mr. Chen, you can't do this!"

His voice was trembling: "If you pump such a large current directly into it, the battery will explode!"

"The fastest fast-charging protocol on the market only dares to use a 1.5C charging rate, and you are..."

He roughly estimated the power: "This is a high rate of over 3C!"

"The chemical reaction inside the battery can't keep up; it will instantly heat up and catch fire!"

Chen Xu just glanced at him: "Begin."

Chen Shiyi connected a brand-new super battery to the charging station.

On the other side, he connected a mobile phone battery that supported the fastest fast-charging protocol on the market for comparison.

The start button was pressed.

Hum—

A massive electrical current sound echoed in the workshop.

Everyone's eyes were fixed on the thermal imager screen.

The color block representing the comparison battery changed wildly.

Blue.

Green.

Yellow.

Orange.

Finally, it turned a glaring bright red!

The temperature soared to seventy degrees!

And the color block representing the super battery only changed from dark blue to light blue, then stayed steadily there.

Eighteen minutes later.

The charging station made a soft sound, and the indicator light turned from red to green.

80% charge, complete.

Chen Shiyi unplugged the connector.

Old Zhang walked up.

The comparison battery was too hot to touch; the thermal imaging showed a surface temperature as high as eighty-five degrees.

And the super battery...

He reached out and touched it.

Warm.

It was merely warm!

It was really just warm!

80% charge in eighteen minutes, yet the heat generated was negligible?

Is this still a lithium battery?

---

"Final test."

"Nail penetration test."

"What?!"

Old Zhang's voice rose sharply: "Mr. Chen! Nail penetration test?!"

"This is a fully charged battery!"

"Piercing a fully charged lithium battery with a steel nail is the most dangerous item in all battery tests!"

"Dening Era's nail penetration tests are all conducted in specialized explosion-proof laboratories, with water mist sprayed around to cool it down, and fire-fighting equipment prepared!"

"We don't have any protection here, if something happens..."

"Begin."

Chen Xu interrupted him.

Chen Shiyi had already firmly secured a freshly fully charged super battery in a bench vise.

Then he started a small hydraulic press.

On the punch head, a specially made steel nail was aimed directly at the center of the battery.

The nail penetration test is an absolute forbidden zone!

"Mr. Chen, I beg you!"

Old Zhang's tone was almost pleading: "This will really cost lives!"

Chen Xu did not respond.

Chen Shiyi's finger was already on the start button.

Old Zhang closed his eyes in despair.

The hydraulic press emitted a slight hum.

The steel nail slowly descended under hydraulic drive.

One second.

Two seconds.

Three seconds.

Old Zhang peeked through his fingers at the other side.

The steel nail made contact with the battery casing.

The casing dented slightly.

Then—

Pfft.

The steel nail pierced inside.

No sparks.

No smoke.

No explosion.

The voltage monitoring curve on the side dropped a small amount, but after only one second, it stabilized again in the usable range.

The battery was still working normally!

Old Zhang stood dazed in the corner.

He looked at the bright steel nail stuck in the battery, and he was completely stunned.

This is not scientific.

This is not physics.

It completely subverted all the cognition he had built up over thirty years!

A lithium battery pierced by a steel nail, not only did it not explode, but it could actually still work normally?!

"Old Zhang."

Chen Xu's voice came over.

Old Zhang turned his head mechanically.

"You just said, this would explode?"

Chen Xu pointed to the super battery that had been pierced by the steel nail but was still working stably.

Old Zhang's lips moved, but he couldn't say a single word.

Chen Xu turned and walked to the other end of the workshop.

That was where the frame of the Gale was parked.

"Battery testing complete, no issues whatsoever."

Chen Xu's voice echoed in the workshop.

"Now, prepare to assemble the Gale prototype."

"In one week, I want to see fifty finished vehicles that can be driven on the road."

Old Zhang was still slumped in the corner.

And Chen Xu had already walked out of the workshop.
