The power battery industry will develop towards "cobalt free" in the future

At present, both automobile and battery companies are scrambling to make a layout in the power battery industry and making great efforts to improve the safety and endurance technology.On September 23, Tesla released the latest battery technology achievement "4680 cell", which has three innovations in technology: first, it is extremely core with no cobalt, high nickel and negative silicon;2. Launch the large-cell battery with the shape of infinite ears, which has made breakthroughs in the shape and structure of the battery module;3. Implement the dry electrode to simplify the process to reduce the battery cost.
On October 15, byd changsha factory blade battery production line officially put into production.Lithium iron phosphate is selected as the basic material for the blade battery, and CTP modular technology is added to make the battery pack flat in structure, so that more cells can be carried in the same battery pack, the energy density increases, and the cost is reduced.
On Oct 16, Zeng Yuqun, chairman of Ningde Times, said that Ningde Times has designed a highly integrated and robust internal short-circuit proof electrode for its 811 battery, which can carry out various abuse tests without fire or smoke.The so-called "811 ternary battery", namely the battery nickel, cobalt, manganese three ratio of 8:1:1 ternary lithium battery, which mainly through the "nickel drop cobalt" to ensure the safety of the battery.

From the perspective of the efforts made by the above auto companies and battery companies, the future battery will develop towards cobalt-free under the condition of both safety and endurance.
