How many years can the ternary lithium battery used?

According to the current technical level of ternary lithium batteries, if used properly, it can be used for at least 5 years on electric vehicles. If used improperly, the 2-3 year lithium battery life will be attenuated.

The so-called use or not, mainly depends on whether you can abide by the principle of shallow filling and shallow, do not overuse.

Introduction:

The ternary polymer lithium battery refers to a lithium battery using a lithium nickel cobalt manganese ternary positive electrode material for the positive electrode material. There are many kinds of positive electrode materials for the lithium ion battery, mainly lithium cobaltate, lithium manganate, lithium nickelate, and ternary materials, lithium iron phosphate and the like. At present, the ternary material battery replaces the widely used lithium cobalt oxide battery, and is widely used in the field of notebook batteries.

Ternary polymer lithium battery performance:

The material with relatively balanced capacity and safety has better cycle performance than normal lithium cobaltate. Its nominal voltage is only 3.5-3.6V in the early stage due to technical reasons. However, there are restrictions on the scope of use, but until now, with the formulation 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.

Terpolymer lithium battery status:

SANYO, PANASONIC, SONY, LG, and SAMSUNG have launched batteries for ternary materials. A considerable number of notebook battery lines have replaced the previous lithium cobalt oxide batteries with batteries of ternary materials, SANYO. In the SAMSUNG column battery, the production of lithium cobalt oxide batteries turned to ternary cells was completely discontinued. At present, most of the small high-power batteries at home and abroad use ternary cathode materials.

Ternary lithium battery overview

Since the electrolyte materials constituting the lithium battery are different, the lithium ion battery is also classified into a ternary lithium battery and a liquid lithium ion battery. The ternary lithium ion battery is the same as the positive and negative materials of the liquid lithium ion battery, and the battery works similarly, and the electrolytes are different from each other. The ternary lithium battery is light in weight, strong in energy storage capacity, good in discharge performance, and can cause various shapes and has a long life. The electrolyte of the ternary lithium battery is a solid electrolyte. Compared with the liquid electrolyte of the liquid lithium ion battery, the ternary lithium battery can cause various shapes to improve the specific capacity of the battery.
