BYD (China) top 3 lithium battery manufacturer in the world

Reference value of occupancy rate: 9.52%; installed capacity: 10GWH.

Global position: BYD is the world's leading manufacturer of rechargeable batteries. BYD's blade battery is unique in the world.

Overview and technical features: BYD Co., Ltd. was founded in 1995 and listed on the main board of Hong Kong on July 31, 2002. The company is headquartered in Shenzhen, Guangdong, China. It is a world-renowned company with three major industrial clusters of IT, automobiles and new energy. High-tech private enterprise.

BYD has built nine production bases in Guangdong, Beijing, Shaanxi, Shanghai, Tianjin and other places, and has branches or offices in the United States, Europe, Japan, South Korea, India and other countries, as well as in Taiwan and Hong Kong.

BYD's IT industry mainly includes rechargeable batteries, chargers, electro-acoustic products, connectors, LCD modules, plastic mechanical components, metal parts, hardware electronic products, mobile phone keys, keyboards, flexible circuit boards, microelectronics Products, LED products, optoelectronic products, etc., as well as mobile phone decoration, mobile phone design, mobile phone assembly business, etc. BYD's major customers include Nokia, Motorola, Samsung and other top customer groups in the international communications industry.

As the world's leading manufacturer of secondary rechargeable batteries, BYD's IT and electronic components industry has covered all core components and assembly businesses of mobile phones. Nickel batteries, mobile phone lithium batteries, and mobile phone keys have reached the first place in the global market share. . BYD was once awarded the first place in the "Best Listed Company Management Award in 2002" by the world authoritative publication "Asia Money". It is worth mentioning that on September 27, 2008, Sino-American Energy Holdings, a subsidiary of Berkshire Hathaway, the investment flagship of the famous American investor "stock god" Warren Buffett, announced that it would pay HK$8 per share. subscribed for 225 million shares of BYD at a price of about 10% of the shares after the allotment of BYD, and the total transaction amount was about 1.8 billion Hong Kong dollars (equivalent to 230 million US dollars. Buffett's investment expressed the recognition of BYD's development prospects and brand value. .

BYD has entered into a memorandum with Germany's Daimler AG to launch a joint venture and cooperation on electric vehicles. Due to the advanced experience of both parties in electric vehicle architecture and battery technology and electric drive system, the integration will be achieved. After the establishment of "Qinghai Salt Lake BYD Resources Development Co., Ltd." jointly established by BYD and Yanhu Co., Ltd., the construction of "an annual output of 30,000 tons of battery-grade lithium carbonate project" was started. BYD has reached a partnership with Arsenal Football Club to become the official global exclusive car and bus partner of Arsenal. BYD became the 100th partner of Baidu's Apollo program. BYD and Changan Automobile have reached a strategic cooperation to establish a power battery joint venture.

TOP energy storage battery

BYD realizes energy storage based on the core technology of LiFePO4 battery, forming technical support for the smart network. Relying on advanced LiFePO4 battery technology, BYD battery energy storage power station can meet the needs of energy storage and peak and valley regulation. , solar energy and other new energy power fluctuations to smooth. At the same time, compared with existing energy storage technologies such as pumped storage, compressed air energy storage, and flywheel energy storage, the BYD energy storage power station has obvious advantages in cost and operating life, and the energy storage efficiency is as high as 90%, which is much higher than 60-70% of the pumped storage energy, the economic benefits are very prominent, the demand is huge, and the application prospect is broad. It can be called the best manufacturer of home battery storage and battery energy storage systems in the world.

BYD's pure electric vehicles mainly use two kinds of batteries, one is a ternary lithium battery, and the other is a lithium iron phosphate battery. As a pioneer of domestic new energy vehicles, BYD is one of the first car companies to launch new energy vehicles. For example, Qin, e6 and other models were launched at this time. At this time, BYD's pure electric vehicles use lithium iron phosphate batteries. After all, BYD has been developing lithium iron phosphate batteries before. Lithium iron phosphate batteries are also its flagship products, and it is the earliest and largest LiFePO4 battery manufacturer.

BYD blade battery

It is worth mentioning that BYD once launched a blade battery, which is a lithium iron phosphate battery. The blade battery has been innovated in structure. For example, the same volume can increase the energy density by 50%, which has caught up with the energy density of the ternary lithium battery in the same period. Importantly, costs have also been significantly reduced by 30%, while security has been greatly improved. Therefore, BYD's blade battery is unique, very distinctive, and an exclusive product.

Compared with the ternary material battery used in the Ningde era, the ternary material has higher energy density, but less safety. BYD uses a lithium iron phosphate battery, which has a lower energy density than ternary materials, but a higher safety factor. In fact, the Ningde era bet on ternary material battery technology, which is more of a product of the times. For example, new energy has a lot of government subsidies, and the subsidy condition is that the longer the battery life, the higher the subsidy. All new energy vehicle companies must use domestic battery technology if they want to get subsidies.

BYD pays more attention to safety and does not deliberately pursue energy density. For example, BYD's blade battery is much more difficult to repair than the Ningde era, because the blade battery can only take care of the broken part. The Ningde era battery is significantly better than the blade battery in terms of charging speed.
