NEGATIVE ELECTRODE ACTIVE MATERIAL FOR NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY, METHOD FOR PRODUCING THE SAME, AND NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY

摘要

A negative electrode active material for a non-aqueous electrolyte secondary battery includes an element capable of forming an intermetallic compound with lithium. The negative electrode active material has a water content of 0 to 0.04 molecule per atom of the element. The non-aqueous electrolyte secondary battery includes a negative electrode including the negative electrode active material, a positive electrode, a separator separating the negative electrode and the positive electrode, and a non-aqueous electrolyte.
