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-xPO4, 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.
