Abstract
A process for producing a ceramic material including providing an aqueous solution comprising at least one transition metal ion and one or more further transition metal ion and/or one or more additional ion; adding to the aqueous solution a quaternary ammonium or phosphonium hydroxide comprising at least one alkyl group containing about 8 or more carbon atoms to form a combined aqueous solution; mixing the combined aqueous solution to form a gel; transferring the formed gel to a furnace; and heating the formed gel to a temperature sufficient for a time sufficient to calcine the gel to form a solid ceramic material. The process in accordance with the present invention provides an improved ceramic material, in some embodiments of which is suitable for use in the cathode material of a lithium ion battery.
