Classification by positive and negative materials
1. Lithium cobaltate battery
Due to the good molecular structure of lithium cobaltate chemical elements so the battery structure is stable, high storage capacity ratio, outstanding overall performance, but its security is poor and the cost is very high. Lithium cobalt acid battery is mainly used in small and medium-sized batteries, which are widely used in small and medium-sized laptops, touch screen cell phones, MP3/4, laptops and digital cameras, small and medium-sized electronic equipment and instruments. The comprehensive performance of lithium cobalt acid battery is outstanding, and the standard voltage is often 3.7V.
2. Lithium manganate batteries
Lithium manganese acid batteries can be discharged at a current of 20-30A, and have the appropriate heat buildup. The material cost of lithium manganate battery is low, safety and low temperature performance index is good. Since its material itself is not too stable and easy to decompose and produce gas, it is mostly used to mix with other materials to reduce the cost cost of electric cells. The cycle life of lithium manganate battery decays faster and is prone to bulge, and its high temperature performance index is poor and its life is relatively short. Its nominal voltage is 3.7 V. Lithium manganate batteries are mainly used in hardware tools accessories, medical devices, and their hybrid cars and new energy vehicles.
3. Lithium iron phosphate rechargeable batteries
Lithium phosphate has very good electrochemical safety performance and low resistance. In the completion of the entire process of charging and discharging, lithium iron phosphate rechargeable batteries inside the battery structure will not produce much change, but also will not occur violent explosions. Even in the event of a short circuit, overcharging, being collision and other unexpected situations, is still very safe.
Classification by internal structure of raw materials
1. Lithium metal batteries
Lithium metal batteries are usually used manganese dioxide as the battery cathode material, lithium metal or its alloy steel metal as the negative electrode material. Lithium metal battery is a rechargeable battery using non-aqueous electrolyte solution.
2. Lithium ion battery
Lithium ion battery is usually used lithium alloy steel metal oxide as the battery cathode material, graphite material as the negative electrode material. Lithium-ion battery is a rechargeable battery using non-aqueous electrolyte.
Classification by shell material
1. Steel-cased rechargeable batteries
The vast majority of battery manufacturers use steel as the battery shell material, because the physical stability of steel materials, pressure resistance is much higher than the aluminum shell material.
2. Aluminum Case Rechargeable Battery
Aluminum shell rechargeable batteries are divided into hard shell and soft shell. As for the positive electrode material, there are many kinds.
3. Polymer lithium battery
Polymer lithium battery shell is a class of polymer raw materials, most of them are silver-white. Lithium polymer batteries are mainly used in car electronic enterprise products (GPS positioning tracker battery, tire pressure detector battery, car recorder battery), shared bicycle, solar energy storage lights, ultra-low temperature walkie-talkies, etc.
