Electrochemical property of honeycomb type all-solid-state Li battery at high temperature

Abstract

A performance at high temperature of all-solid-state battery with LiMn 2O4/honeycomb Li0.35La0.55TiO 3/Li4Mn5O12 configuration was examined. The charge and discharge capacities increased with test temperature until 100°C by favorable Li ion conductivity of electrolyte. At°C, deterioration of the performance was observed due to instability of electrode material. It is found that the all-solid-state battery can be operated until 100°C. The discharge capacity at 100°C was 74 μA h cm-2 at current density of 100 μA cm-2.
