Abstract
A hydrothermal synthesis for LiFePOis 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 LiFePOis obtained in a predesigned form.
