Patent attributes
A lithium-ion battery includes a positive electrode that has a current collector and a first active material and a negative electrode that has a current collector, a second active material, and a third active material. The second active material includes a lithium titanate material and the third active material is a material that can be one or more of the following: LiMn2O4, LixVO2 where x is between 0.05 and 0.4, LiMxMn(2−x)O4 where M is a metal and x is less than or equal to 1, V6O13, V2O5, V3O8, MoO3, TiS2, WO2, MoO2, RuO2, and combinations thereof. The third active material exhibits charging and discharging capacity below a corrosion potential of the current collector of the negative electrode and above a decomposition potential of the first active material.
