Violet tungsten oxide may be applied for producing window heat insulation film, which mainly reflects its thermal insulation properties. Violet tungsten oxide powder also has good chemical activity, small internal resistance and excellent lithium ion diffusion, so that it can be used as a negative electrode material for ultra-high speed charge and discharge lithium batteries. Such ultra-high speed charge and discharge lithium battery using violet tungsten oxide as negative electrode material is characterized in that the power density and the…
