Spinel Li1 + xMn2O4 synthesized by coprecipitation as cathodes for lithium-ion batteries

Abstract Spinel Li 1 + x Mn 2 O 4 was prepared by the coprecipitation of LiOH and Mn(OH) 2 in ethyl alcohol. The particle size is about 2 μm with a narrow distribution. Cyclic voltammetry experiments using the Li/ethylene carbonate + dimethoxyethane + LiClO 4 /Li 1 + x Mn 2 O 4 cells show good reversibility of lithium deintercalation and intercalation in the spinel phase of Li 1 + x Mn 2 O 4 The initial reversible capacities are about 120 mA h/g and 140 mA h/g for x = 0 and x = 0.2, respectively.
