PROCESS FOR PRODUCING POSITIVE ELECTRODE MATERIAL COMPOSITION FOR LITHIUM SECONDARY BATTERY

摘要

A process for producing a positive electrode material composition for lithium secondary battery, in which in the mixing of a polymer, an electrode active material and a conduction aid, uniform mixing can be conducted while satisfactorily suppressing any decomposition and deterioration of the polymer, and in which high productivity in time and cost can be achieved with satisfactory attention paid to environment. There is provided a process comprising the steps of mixing a polymer solution, an electrode active material and a conduction aid together to thereby obtain a slurry mixture and evaporating the solvent of the polymer solution from the slurry mixture to such an extent that the mixture retains fluidity.
