The high-rate performance of the newly designed Li4Ti5O12/Cu composite anode for lithium ion batteries

Abstract The Li 4 Ti 5 O 12 /Cu composite was synthesized by an electroless deposition of Cu particles. The content of Cu in the composite was determined as 1% by the energy-dispersive spectroscopy (EDS) technique. The conductivity of the Li 4 Ti 5 O 12 /Cu composite was almost two orders of magnitude higher than the pristine Li 4 Ti 5 O 12 . Furthermore, the high rate discharge capacity and cycling stability of the pristine Li 4 Ti 5 O 12 was significantly improved by the Cu additive.
