Abstract

Blue hydrogenated lithium titanate (LTO) was prepared by treating industrial grade white LTO at 500 °C under a 40 bar H2 atmosphere. This process improves the Li-ion diffusivity and electronic conductivity, leading to enhanced specific capacity and rate capability in lithium-ion batteries.
