What are the advantages of cobalt-free lithium batteries

Regarding the cobalt metal in cobalt-lithium batteries, it is a rare metal in itself, and it is also one of the most expensive metal materials in automotive battery materials. Data shows that the domestic reference price of cobalt metal on February 18 was 277,500 yuan/ton. Therefore, the current cost of lithium iron phosphate batteries without cobalt is 0.6/wh, and the cost of ternary lithium batteries with cobalt reaches 0.85/wh. Therefore, it is not difficult to see that the cobalt-free lithium battery has advantages in processing cost. Taking the lithium iron phosphate battery without cobalt lithium battery as an example, the service life is longer. Calculated according to overflowing discharge, the current cycle life of lithium iron phosphate batteries can reach about 2000 times, while the number of cycles of overflowing ternary lithium batteries is about 1000 times. Therefore, longer service life is also one of the advantages of cobalt-free lithium batteries. At present, ternary lithium batteries on the market are more used in family cars, and cobalt-free batteries are used in passenger cars, public transportation vehicles or electric logistics vehicles. According to current applications, there are few safety incidents in buses, but There have been countless spontaneous combustion incidents caused by batteries in family cars. And in theory, cobalt-free batteries are safer than ternary lithium batteries. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
