Abstract
There is provided a method for producing an active material for a nonaqueous secondary battery, including firing an adherend in which a compound containing an element A (at least one element selected from among B, Al, Ga, In, Si, Ge, Sn, Mg and transition metal elements) is adhered to a particle surface of a material capable of being doped and dedoped with lithium ions, in a water-containing atmosphere so that weight increasing rate of the adherend is in a range of 0.1% by weight or more and 5.0% by weight or less, and firing the adherend.
