From knock-off old-man's electric vehicles to industrial giant

Chapter 274 What does it mean that even batteries need to be released first?

what?
Can a consumer-grade battery used in a flagship phone really achieve a 5000mAh capacity and a charging efficiency of over 50W?!

Yu Chengdong heard this news.

My first thought was, "What will be the cost?"

The joint laboratory they established with the battery factory has this type of battery cell.

You want high energy density? No problem.

Under the conditions of a laboratory, you can conjure up any kind of bizarre stuff.

Let alone 5000mAh, even a 6000-7000mAh battery of the same size with 100W charging efficiency is manageable if you grit your teeth and persevere!
However, this type of battery either has very demanding manufacturing processes and materials.

It might have a major inherent defect, such as what ATL mentioned, where it expands and explodes after two or three hundred charge-discharge cycles, or it might overheat during charging and pose an explosion risk...

"You mean StarCraft developed a flagship-level battery that's practically flawless in every aspect?"

When Yu Chengdong arrived, he stared blankly at the two types of battery cells!
--hiss!!
"Well, theoretically speaking, both of these battery models are in line with the flagship positioning of our Mate 20 this year," Liu Zecheng said after a moment of silence.

He then pulled up the performance test curves for these two battery cells on his computer.

"Regarding the characteristic that Polestar batteries have a significantly higher cycle life than other consumer-grade battery cells, we have also specifically checked it. Whether it is the sample or the mass-produced version used in the Vivo X20 last year, it basically matches the minimum of 700-800 cycles mentioned by the other party."

It's scary.

With a cycle life two to three hundred times longer than other suppliers, how can its energy density still be far ahead?

They originally thought that ATL, with its incremental upgrades this year, could close the gap with Polestar batteries, since a 4300mAh installed capacity is not insurmountable.

But now it seems.

The gap has widened even further!

A blink of an eye.

Other brands have already entered the 5000mAh era.

Is this the strength of China's leading power battery manufacturer?
Yu Chengdong saw the news a few days ago and felt that the title was somewhat undeserved.

After all, Xingchen follows the lithium iron phosphate route.

ATL and CATL have dominated the battery industry for many years.

But now he has a new understanding of this company.

"No, if we're going to go, we have to go for the best. This is an opportunity."

Yu Chengdong immediately shook his head.

"If the battery capacity can be increased to 5000mAh, then we can be even more aggressive in optimizing the chip's power consumption and further improve heat dissipation, resulting in even stronger benchmark scores and real-world performance!"

He realized the key point.

The performance release of mobile phone chips at this stage is often extremely limited, which depends on two factors: power consumption and heat dissipation.

In order to maintain at least seven or eight hours of usage time, manufacturers have to optimize scheduling in various ways and limit the power consumption of the chip under extremely harsh conditions.

Once the power consumption increases, the meager battery capacity won't be able to keep up.

However, with larger battery capacities, manufacturers will inevitably continue to increase chip power consumption in order to improve benchmark scores and performance.

Even though mobile phone battery capacity has doubled in just a few years!

In the end, it can only be used for "about one day"!
This is the so-called "range paradox".

Yu Chengdong was calculating how much performance improvement a 20% increase in battery capacity could bring while maintaining battery life.

A growing sense of urgency filled my heart.

This year, Kirin chips must prove themselves once again!
……

On the other hand, Vivo and Xiaomi's reactions were equally shocking!
The release date for the Xiaomi MIX 2S has been set for March, and it will be equipped with a Polestar battery, increasing the capacity to 4000mAh.

Even though it hasn't been released yet, sales expectations are very high.

After all, it was the first to feature the Snapdragon 845. But overall, the second half of the year is the main battleground for mobile phone manufacturers to compete on sales and configurations. Each company will bring out its top-of-the-line configurations to compete, and they will pile on every feature they can in their models.

"Mr. Lei, of Xingchen's two battery models this year, which one should we choose?"

After the purchasing department received the samples and completed the testing, they immediately reported to Vice President Lin Bin. After reviewing the sample report, Lin Bin ultimately submitted the final decision to Lei Jun.

He felt he couldn't make that decision.

Xingchen actually got them two set meals!!

The first package was expensive, and it was still a case of "you get what you pay for."

The second package was even more expensive, more than doubling the price, but the fact that the device had a capacity exceeding 5000mAh was incredibly tempting.

Without Starlight, their flagship phones this year might not even have exceeded 4000mAh in capacity.

My head was buzzing.

Are flagship phones about to enter the 5000mAh era?

"Their energy density breakthrough is too exaggerated. I thought ATL could catch up this year..." After comparing the cell samples provided by both sides, with the actual parameters and performance tests on his face, Lin Bin finally slowly came to his senses. Xingchen's strength in battery manufacturing is undeniable.

This sample is so impressive that it's enough to shock the entire industry!

Lei Jun only glanced at it before his head started spinning.

"This purchase price is even more expensive than last year..."

This star... is so cruel!
Xiaomi's flagship phone this year is priced at just over 3,000 yuan, with the high-end version costing at most 4,000 yuan. Therefore, the budget for battery procurement is destined to be not too high. Polestar batteries are more like luxury items for them at this price point, which is why they contacted ATL again.

Let's see if we can find a cost-effective solution this year.

It now seems that all expectations have been dashed.

The 5000mAh capacity is irresistible not only to mobile phone manufacturers, but also to flagship phone users who pursue a good experience!

On one side is a capacity of 3500-3800, and on the other side is a capacity of 4500-5000. This gap has widened to the point where a choice has to be made.

If the same power consumption is used, the user's battery life may differ by more than two hours.

This is an exaggeration.

No matter how many online trolls and reviewers try to hype it up, it won't be easy to close the gap.

Moreover, Polestar batteries have high fast charging efficiency.

This generation of battery cells can accommodate 50W fast charging, and the combination of the two has almost reshaped the landscape of mobile phone battery life experience.

“Mr. Lei, if other companies also purchase batteries from Xingchen, then it’s only natural to pass on the battery costs to the selling price. Besides, we also have the collector’s edition…” Lin Bin suggested.

"I think so too, but according to StarCraft, the production capacity of the second-generation Polaris A is limited by the process and yield, and the supply this year is extremely limited?"

Wang Teng couldn't help but interject, "What do they mean by this? Are they suggesting we negotiate an exclusive first release?"

As soon as these words came out.

The expressions on everyone's faces in the conference room turned strange, and a very eerie feeling welled up in their hearts.

Lei Jun, however, was very familiar with this and nodded.

"If it's a multi-purchase model, there has to be one exclusive first release."

As for how to decide?
It's all about money!
The voice just fell.

Everything went black before everyone's eyes!
Go against Tiangang!

It's one thing to vie for the first release of Snapdragon chips every year.

Now they're going to talk about exclusive first-release battery supply?
