Abstract
A lithium rechargeable battery includes a cathode plate having a cathode current collector layer; and a cathode layer composed of particles of a cathode active material; an anode plate that is spaced apart from the cathode plate and having an anode current collector layer and an anode layer composed a mixed anode active material that is a mixture including particles of a spinel lithium titanium oxide (LiTiO) and nanotubes of a lithium titanium oxide (LiTiO, where 0<x<2); and a polymer electrolyte disposed between the cathode plate and the anode plate. The cathode active material may contain only one cathode active material or be a mixed cathode active material composed of a mixture of particles of carbon-coated lithium iron phosphate (LiFePO) that are nanoparticles of lithium iron phosphate coated with carbon particles and particles of a lithium transition metal oxide.
