Nano Tungsten Oxide Applied in Cobalt-free Lithium Ion Battery
As one of the most hot topics recently, cobalt-free lithium ion battery is considered as an upgraded version of the current commercial ternary lithium ion battery. Because of their higher energy density and lower production costs, they are popular among many battery manufacturers. As a typical transition metal N-type semiconductor material, how should nano tungsten oxide be used in cobalt-free lithium battery? Nano tungsten oxide can be used as a modifier for the anode material of cobalt-free batteries, and can also be used to produce high-performance anode materials. In terms of cathode materials, the use of WO3 can not only reduce the use of cobalt metal, but also effectively improve the specific capacity and thermal stability of the product. In terms of anode materials, the use of WO3 can significantly improve the rate performance and lithium storage kinetics. As we all know, the biggest cost of new energy vehicles lies in power batteries. As far as the ternary lithium ...
