The difference between pure cobalt batteries and ternary batteries

2022 05/04

Ternary polymer lithium battery refers to a lithium battery whose positive electrode material uses nickel cobalt lithium manganate (Li(NiCoMn)O2) ternary positive electrode material. The ternary composite positive electrode material is made of nickel salt, cobalt salt and manganese salt as raw materials. The ratio of nickel, cobalt and manganese can be adjusted according to actual needs. The battery with ternary material as the positive electrode is more safe than lithium cobalt oxide battery, but the voltage is too low, and it will be obviously used in mobile phones (the cut-off voltage of mobile phones is generally around 3.0V). feeling of insufficient capacity.
Ternary polymer lithium battery refers to a lithium battery whose positive electrode material uses lithium nickel cobalt manganese ternary positive electrode material. There are many kinds of positive electrode materials for lithium ion batteries, mainly lithium cobalt oxide, lithium manganate, lithium nickel oxide, and ternary materials. , lithium iron phosphate, etc. At present, the batteries of ternary materials have replaced the lithium cobalt oxide batteries that were widely used before, and are widely used in the field of notebook batteries.

Materials that are relatively balanced in terms of capacity and safety have better cycle performance than normal lithium cobalt oxide. In the early stage, due to technical reasons, the nominal voltage was only 3.5-3.6V, which limited the scope of use. With continuous improvement and perfect structure, the nominal voltage of the battery has reached 3.7V, and the capacity has reached or exceeded the level of lithium cobalt oxide battery.

The world's top 5 battery cell brands SANYO, PANASONIC, SONY, LG, SAMSUNG have launched ternary material batteries, and quite a few notebook battery lines have replaced the previous lithium cobalt oxide batteries with ternary material batteries, SANYO, In terms of SAMSUNG column batteries, the production of lithium cobalt oxide batteries has been completely stopped and turned to the manufacture of ternary batteries. At present, most of the small high-rate power batteries at home and abroad use ternary cathode materials.
