NEGATIVE ELECTRODE FOR BATTERY AND LITHIUM BATTERY USING THE SAME

摘要

A negative electrode for battery is provided. The negative electrode comprises a current collector and a negative electrode material coat on the current collector. The negative electrode material comprises carbonaceous material, binder, and lithium titanium oxide compound, wherein in the negative electrode material coat, the carbonaceous material has total weight percentage content higher than that of the lithium titanium oxide compound; and the negative electrode material coat comprises at least two layers; in the outermost layer of the negative electrode material coat, the carbonaceous material has weight percentage content lower than that of the lithium titanium oxide compound; in other layers of the negative electrode material coat, the carbonaceous material has weight percentage content higher than that of the lithium titanium oxide compound. A lithium ion battery using the negative electrode is provided.
