What is a lithium battery? What is commonly used in industrial lithium batteries?

        Lithium batteries are divided into lithium batteries and lithium ion batteries. Lithium batteries use metal lithium or lithium alloys as negative electrode materials and use non-aqueous electrolyte solutions; lithium ion batteries are a type of secondary battery (rechargeable battery), which is mainly Rely on lithium ions to move between the positive and negative electrodes to work. The lithium battery we usually talk about is actually a lithium-ion battery. Today we will mainly introduce lithium-ion batteries. Lithium-ion batteries currently on the market are divided into three categories:

        1. Ternary lithium battery: Ternary polymer lithium battery refers to a lithium battery that uses lithium nickel cobalt manganese ternary cathode material as the anode material. There are many kinds of cathode materials for lithium ion batteries, mainly lithium cobalt oxide, lithium manganate, Lithium nickelate, ternary materials, lithium iron phosphate, etc. Ternary materials combine the advantages of three types of materials: lithium cobalt oxide, lithium nickel oxide and lithium manganate, and have excellent characteristics such as high capacity, low cost, and good safety. They gradually occupy a certain market share in small lithium batteries and are The power lithium battery field has good development prospects, and this type of battery currently accounts for the largest proportion in the industrial vehicle market.

       2. Lithium manganate: Lithium manganate is one of the more promising lithium ion cathode materials. Compared with traditional cathode materials such as lithium cobalt oxide, lithium manganate has abundant resources, low cost, no pollution, good safety, and rate performance. Good and other advantages, it is an ideal power battery cathode material, but its poor cycle performance and electrochemical stability greatly limit its industrialization. Lithium manganate mainly includes spinel type lithium manganate and layered structure lithium manganate. Among them, spinel type lithium manganate has a stable structure and is easy to realize industrial production. Nowadays, the products on the market have this structure. Spinel lithium manganate belongs to the cubic crystal system, Fd3m space group, and the theoretical specific capacity is 148mAh/g. Due to the three-dimensional tunnel structure, lithium ions can be reversibly extracted from the spinel lattice without causing structural damage. It collapses, so it has excellent rate performance and stability.

　　3. Lithium iron phosphate: Lithium iron phosphate has only appeared in recent years as a material for lithium power batteries. In 2005, a large-capacity lithium iron phosphate battery was developed in China. Its safety performance and cycle life are unmatched by other materials, and these are also the most important technical indicators of power batteries. 1C charging and discharging cycle life is up to 2000 times. Single-cell battery will not burn or explode when overcharged at 30V. Lithium iron phosphate cathode materials make large-capacity lithium-ion batteries easier to use in series to meet the needs of frequent charging and discharging of electric vehicles. Lithium iron phosphate has the advantages of non-toxic, non-polluting, good safety performance, wide source of raw materials, low price, and long life. It is an ideal cathode material for a new generation of lithium-ion batteries.

　　 At present, the largest proportion of the industrial vehicle market is the ternary battery, but the current safety of the ternary lithium battery is not very high. There have been accidents of explosion and combustion of the ternary battery in China, which is very dangerous in industrial production. Many domestic battery companies have begun to use lithium iron phosphate batteries instead of ternary batteries. Lithium iron phosphate batteries are safe and pollution-free. It is believed that domestic industrial vehicles will use lithium iron phosphate batteries in the future.
