Emulsion-derived lithium manganese oxide powder for positive electrodes in lithium-ion batteries

摘要

Lithium manganese oxide (LiMn_2O_4) used as a positive-electrode material in lithium-ion batteries is prepared by a new water-in-iol emulsion process. An aqueous solution containing lithium and manganese cations is emulsified in kerosene by adding sorbitan monooleate as the surfactant.
