Chapter 38 Battery Pattern
October 2016 was a busy month.

Perhaps it was stimulated by the Thor battery.

First, Biyadi released a new type of ternary lithium battery, which increased the energy density of the battery to 110-120 watt-hours per kilogram.

Previously, the energy density of their company's ternary lithium batteries was between 90 and 100 watt-hours per kilogram.

At present, the batteries used in BYD passenger cars are basically ternary lithium batteries, also known as ternary polymer lithium batteries. This type of battery refers to the positive electrode material using nickel-cobalt lithium manganate or nickel-cobalt lithium Lithium battery with ternary cathode material.

Their company's ternary lithium battery uses nickel-cobalt lithium manganate as the positive electrode material, which, like nickel-cobalt-aluminate lithium battery, has a higher energy density while ensuring a balanced battery life and stability, so it has become the current The first choice for consumer-grade electric vehicle power batteries.

Lithium cobalt oxide was the most widely used battery material in the world before.However, cobalt resources are increasingly scarce and expensive, and there are safety hazards in the use of lithium cobalt oxide batteries.

Therefore, the new generation of lithium nickel cobalt manganese oxide replaces more than two-thirds of the cobalt in lithium cobalt oxide with relatively cheap nickel and manganese, and the cost advantage is very obvious.

Compared with lithium manganese oxide and lithium iron phosphate, lithium-ion battery cathode materials, nickel-cobalt lithium manganese oxide material and lithium cobalt oxide are very close in terms of electrochemical performance and processing performance, making nickel-cobalt lithium manganese oxide material a new battery materials and gradually replace lithium cobalt oxide, becoming the darling of the new generation of lithium-ion battery materials.

And Dongying Panasonic is not to be outdone.

After using Daniu electric vehicles as guinea pigs before, Panasonic's super lithium batteries have also become more and more perfect.

Officially released a new generation of 18650 lithium battery cells, claiming an energy density of 220 watt-hours per kilogram.

Similarly, domestic Ningde batteries have also exploded, launching lithium ferrous sulfate batteries with an energy density of 110-115 watt-hours per kilogram, and ternary lithium batteries with an energy density of 135-145 watt-hours per kilogram.

The products of Ningde Power Battery Company are mainly lithium-ion power batteries. In the selection of battery materials, lithium iron phosphate, nickel-cobalt-manganese ternary, lithium manganese oxide, lithium cobalt oxide, etc. are mainly used.

At present, lithium iron phosphate batteries are mainly used in buses, while ternary lithium batteries are mainly used in household pure electric vehicles.

As for lithium cobalt oxide batteries, although the energy density has reached 180-190 watt-hours per kilogram, the reasons have already been mentioned.

Cobalt resources are increasingly depleted and expensive, so the launch of lithium cobalt oxide is a loss-making business.

Other Korean Sanxin, LG Chem, and other domestic battery companies are also making frequent moves.

But Huang Junjie didn't care about their actions.

The natural limit and instability of lithium batteries doom them to be unable to compete with Raytheon batteries for a long time.

The lithium manganate battery material is mainly spinel lithium manganate LiMn2O4, the theoretical specific capacity is 148mAh/g, the discharge platform is 4.15V, and the energy density of the material is 614.2 Wh/kg.

The lithium iron phosphate battery has a theoretical specific capacity of 170mAh/g, a discharge platform of 3.4V, and a material energy density of 578 Wh/kg.

The ternary lithium battery (nickel-cobalt-manganese oxide), nickel-cobalt-manganese three raw materials, the theoretical capacity reaches 280 mAh/g, the actual capacity of the product exceeds 150 mAh/g, the voltage platform is 4.3V, and the energy density of the material is 1204 Wh/kg.

This is the theoretical limit of the energy density of the three mainstream lithium batteries currently on the market.

The problem is that the theoretical limit cannot be reached so easily. It is affected by other raw materials and processing technology of the battery. According to the barrel theory, it is not the highest wooden board that determines the capacity of the bucket, but the shortest wooden board, so it is difficult for them to adjust the battery capacity. The energy density is pushed to the theoretical limit.

The theoretical limit of energy density of Raytheon Battery's iron-lead-tin-based battery reaches 15000 watt-hours per kilogram.

Moreover, Huang Haojie has achieved a mass production design with an energy density of 1200 Wh per kilogram.

It's just that it's not necessary for the time being.

Of course, since major battery companies have launched new batteries one after another, Raytheon Battery certainly cannot show weakness.

He plans to release Raytheon 1.5-generation batteries at the end of the year, increasing the energy density to 240 watt-hours per kilogram.

This is also one of his strategies. Every time the battery launched is a little bit stronger than the battery on the market, it constantly forces other battery companies to develop new batteries to compete with Raytheon batteries.

The problem is that Raytheon Battery's batteries do not require research and development costs before the temporary limit energy density of 1200 watt-hours per kilogram.

However, other battery companies have to invest huge R&D costs. When they develop it, Raytheon Battery will improve the battery performance and be a little better than them.

A few more times, it will definitely make them want to die. The just successful research and development has not had time to celebrate, but it turns out that it is a little behind the Raytheon battery. This feeling is simply too painful to live.

It's like a man who is on the verge of eruption, but someone suddenly pours cold water on him, making him absolutely impotent several times.

Huang Haojie wants to drag other battery companies down through this method, coupled with the continuous grabbing of the market.

Raytheon Battery Company official website.

"@雷神软件, Panasonic, Sanxin, Biyadi, and Ningde have all been updated, don't you plan to follow up?" - Qinhuang Hanwu

"Upstairs IQ, the energy density of Raytheon battery is now 190 watt-hours per kilogram, except for Panasonic, which is higher, which is similar to Sanxin LG. In addition, the charging speed is fast, and it is still leading the world for the time being." - Data Emperor
“@DataDi, can leading be arrogant?” — Five Cents
"Sanxin and Panasonic are all rubbish, and lithium batteries are mobile bombs. Don't forget the tragic death of Daniel." - Lei Fan Niu Demon King
"The Huawei mobile phone I use is the Raytheon battery. It's really good. It can be charged almost in seconds, and it doesn't get hot." —Flowers

"@走花向画，Miss Sister, I also use flowers for my career. Are you from Yangcheng? What a coincidence! I am also from Yangcheng..." ——The man in Yushu Linfeng
“@玉树临风的男孩，Brother, they might be bigger than you!” —31 Zhihua

Guancheng Flower is the headquarters of the company.

Yu Mingguang could not help grinning as he saw the sesame blossoms and the steadily increasing sales of mobile phones.

As of October 10, Huawei's global sales of mobile phones have reached 1 million units.

Yu Mingguang knows that Raytheon batteries are indispensable. Without Raytheon batteries that are safe, stable and fast-charging, it is impossible for Huawei's mobile phone sales to reach 1.1 million units so quickly.

He was grateful for his decision, and quickly picked up the phone to call the purchasing department:
"Hey, Mr. Yu! What's your order?" The head of the raw material procurement department asked hastily.

"It's like this, you go to Raytheon Battery Company to purchase 4000 tons of Raytheon cells from them." Yu Mingguang ordered straightforwardly.

"Okay, Mr. Yu, I'll go right away." The head of the raw material procurement department replied immediately.

Yu Mingguang hung up the phone.

The reason why so many Raytheon batteries are purchased is that Yu Mingguang intends to fully promote the use of Raytheon batteries for the company.

After all, Huawei is a company, not only mobile phones, but also notebooks, computers, basic communication equipment, etc. There are many places that need to use batteries.

Lithium batteries are not only expensive, but also have poor service life and safety performance. Compared with Thor batteries, they are really like mobile bombs.

If Huawei fully adopts Raytheon batteries, it will not only reduce costs, but also enhance competitiveness.

After using Raytheon batteries, Huawei found out that the mobile phone heating problem that had plagued Huawei before had been solved.

In fact, Android-based mobile phones generally have heating problems. There are two main reasons. One is that the system is bloated, which leads to high-load operation of the CPU chip; the other is the heating of the lithium battery.

Under these two factors, Android-based mobile phones sometimes seem very hot.

The emergence of Raytheon batteries has successfully solved the problem of battery heating.

Let Huawei's mobile phone's heating situation drop significantly. Of course, Yu Mingguang used a large number of Thor batteries to replace lithium batteries. After all, he is not a fool.
