ALKALI METAL HYDROGEN PHOSPHATES AS PRECURSORS FOR PHOSPHATE-CONTAINING ELECTROCHEMICAL ACTIVE MATERIALS

摘要

The present invention relates general to a method for making an alkali metal hydrogen phosphate of the general formula AxH3-XP04, wherein A is an alkali metal and 0 <= x >= 3, prepared by admixing an alkali metal-containing compound, a phosphate-supplying compound, and water, where water is present in the mixture at a level of from about 5% to 25% by weight.
