Abstract:
An active material, an electrode, and a battery which exhibit high safety in overcharging tests, and methods of manufacturing them are provided. The active material comprises a first metal oxide particle 1 and a second metal oxide particle group 2 attached to a surface of the first metal oxide particle 1. The second metal oxide is at least one selected from the group consisting of zirconia, silica, and tin oxide. The first metal oxide particle 1 contains fluorine atoms from its surface to deepest part.
