Fabrication of 3-dimensional rechargeable lithium-ion battery using Li_0.35La_0.55TiO₃ electrolyte with honeycomb structure

Abstract

Li_0.35La_0.55TiO₃ (LLT) with a honeycomb structure, which has micro-size-holes on both sides of the membrane, was employed as an electrolyte for three-dimensional (3D) all-solid-state rechargeable lithium ion batteries. LiMn₂O₄ and Li₄Mn₅O₁₂ were used as cathode material and anode material, respectively. LiMn₂O₄ / honeycomb LLT / Li₄Mn₅O₁₂ was successfully operated at 130 °C with the discharge capacity of 77 μA h cm^-2 (5.8 mA h g^-1).
