Ternary polymer lithium batteries refer to lithium batteries with ternary cathode materials such as nickel cobalt manganese lithium or nickel cobalt aluminum lithium, which are relatively balanced in terms of capacity and safety. The precursor product of ternary composite positive electrode material is made of nickel salt, cobalt salt, and manganese salt as raw materials, and the proportion of nickel cobalt manganese inside can be adjusted according to actual needs. Ternary lithium batteries have a higher energy density, but their safety is often questioned.

Advantages: High capacity, nominal capacity of 1250mAh, good cycle life, generally 600 to 700 cycles, better than normal lithium cobalt oxide, and good rate discharge

Disadvantages: Low battery energy density, worst safety performance among the three batteries, poor cycling stability and storage performance at high temperatures

Scope of use: Currently, ternary polymer lithium battery cells are widely used in the field of notebook batteries. The world's top five battery cell brands SANYO, PANASONIC, SONY, LG, and SAMSUNG have all launched ternary battery cells.

Lithium Cobalt Acid Battery

Lithium cobalt oxide batteries can be considered as the ancestor of positive electrode materials for lithium batteries, with superior electrochemical performance and high compaction density. Lithium cobalt oxide batteries have stable structure, high capacity ratio, and outstanding comprehensive performance, but their safety is poor and their cost is very high. They are mainly used in small and medium-sized battery cells and are widely used in small electronic devices such as laptops, mobile phones, MP3/4, etc., with a nominal voltage of 3.7V.

Advantages: Stable structure, high capacity ratio, and outstanding comprehensive performance

Disadvantages: However, its safety is poor and its cost is very high

Scope of use: Currently, it is only widely used in the digital electronic product market, such as small electronic devices such as laptops, mobile phones, MP3/4, etc. There are very few people who make car power batteries.
