Top 10 Chinese lithium battery companies

Introduction of lithium battery

Lithium is a metal element, the chemical symbol is Li (its English name is lithium), is a silver white, very soft, chemical performance of the lively metal, in the metal is the lightest. In addition to its application in the atomic energy industry, it can be used to manufacture special alloys, special glass (fluorescent screen glass used in TV sets) and lithium batteries. It is used as the anode of a lithium battery.

Lithium batteries are also divided into two categories: non-rechargeable and rechargeable. A non-rechargeable battery is called a disposable battery, which can only convert chemical energy into electrical energy once and for all, and cannot restore electrical energy to chemical energy (or poor reduction performance). Rechargeable batteries are called secondary batteries. It can change electrical energy into chemical energy to store, in use, and then chemical energy into electrical energy, it is reversible, such as the main characteristics of lithium battery electric energy chemical energy.

Smart portable electronic products require small size and light weight, but the size and weight of the battery is often the largest and heaviest compared with other electronic components. For example, whereas "cell phones" were "bulky and bulky" back then, today's mobile phones are so lightweight. The improvement of the battery plays an important role: it used to be nickel-cadmium battery, but now it is lithium ion battery.

The biggest characteristic of lithium battery is its high specific energy. What is specific energy? Specific energy refers to energy per unit weight or volume. Specific energy is expressed in Wh/kg or Wh/L. Wh is the unit of energy, W is watts, h is hours; Kilograms are kilograms, and L is liters. Here take an example to illustrate: 5 nickel cadmium battery rated voltage for 1  2 v, its capacity is 800 mah, the energy of 0  96 wh (1  2 v & TImes; 0  8 ah). 同样尺寸的5号锂-二氧化锰电池的额定电压为3V，其容量为1200mAh，则其能量为36Wh。 Both the volume of a battery is the same, the lithium manganese dioxide - the specific energy of the battery is nickel cadmium battery 3  75 times!

A nickel-cadmium no. 5 battery weighs about 23g, while a lithium-manganese dioxide no. 5 battery weighs about 18g. - section lithium manganese dioxide battery is 3 v, and two nickel cadmium battery only 2  4 v. Therefore, when lithium battery is used, the number of batteries is small (reducing the volume and weight of portable electronic products), and the working life of the battery is long.

In addition, lithium battery has the advantages of stable discharge voltage, wide operating temperature range, low self-discharge rate, long storage life, no memory effect and no pollution.

The disadvantage of lithium battery is that it is expensive, so it cannot be widely used at present. It is mainly used in handheld computers, pdas, communication equipment, cameras,specials,specials,speciales, instruments and so on. With the development of technology, the improvement of technology and the increase of production, the price of lithium battery will continue to fall, and the application will be more common.

What are the top ten lithium battery enterprises in China

1. BYD

Date of establishment: 2006

Byd's power battery business is mainly distributed in Huizhou and Shenzhen two bases, the main product is lithium iron phosphate power battery. The current effective capacity is 4.5gwh, of which Huizhou 1Gwh and Shenzhen Kenzi 3.5gwh are expected to reach 6Gwh by the end of 2015 and expand to 10Gwh in 2016. BYD's power batteries are for its own use only. BYD's power battery business earned about 3 billion yuan in the first half of 2015.

Why it makes the list: BYD is absolutely the leader of domestic power batteries. Driven by the group's new energy automobile business, its power battery business is far ahead of its competitors in terms of scale. In terms of technical system, BYD, which has always adhered to the technical route of lithium iron phosphate, recently chose ternary material battery in the next generation of vehicles. It is reasonable to believe that no matter what technical route BYD takes, it will be able to do a good job in battery production relying on its years of experience in battery production. In terms of the industrial chain, BYD adheres to the strategy of the whole industrial chain. From materials to batteries, motors, electronic control and vehicles, BYD chooses to do it by itself. The closed-loop development model of the industrial chain can only be played by a company of BYD's size.
