C30B29/14

Manufacturing method of composite oxide which is represented by formula LiMPO.SUB.4., where m means iron and manganese
12609314 · 2026-04-21 · ·

A hydrothermal synthesis for LiFePO.sub.4 is provided. First, each raw material solution is prepared using a degassed water in advance, second, those solution are mixed by dripping in a fixed order, and then those materials are reacted in a hydrothermal synthesis, so that LiFePO.sub.4 is obtained in a predesigned form.
