Abstract
A method for preparing a lithium titanium phosphate, wherein a sol-gel process is used to prepare the phosphate, includes producing a sol from source materials; converting the sol to a gel; and drying the gel to obtain a corresponding powder comprising the lithium titanium phosphate. In a substep, the method further includes adding titanium(IV) isopropoxide to water to produce precipitates of titanium hydroxide oxide, cooling a system down to a temperature of less than 10° C., and redissolving the precipitates by adding nitric acid to form an aqueous TiOnitrate solution. The lithium titanium phosphate has a general composition LiMTi(PO)(SiO), wherein M=Al, Ga, In, Sc, V, Cr, Mn, Co, Fe, Y, La—Lu, wherein 0≤x≤0.5, and wherein 0≤y≤0.5.
