MANUFACTURE OF NONAQUEOUS ELECTROLYTE LITHIUM ACCUMULATOR AND POSITIVE ELECTRODE ACTIVE MATERIAL THEREFOR

摘要

PURPOSE:To provide a positive electrode for a nonaqueous electrolyte lithium accumulator having high voltage and high energy density, capable of being supplied stably at a low cost with small environmental pollution caused by heavy metals. CONSTITUTION:By adding manganese carbonate to a mixture of iron compound and lithium salt and burning the mixture. LiFe1-xMnxO2 is synthesized, which is used as an active material for the positive electrode 1 of a nonaqueous electrolyte lithium accumulator.
