摘要：
This electrode for nonaqueous electrolyte secondary batteries is provided with a collector, an active material layer that is formed on the collector, and an assembly of filler particles, said assembly being present on the surface of the active material layer. The filler particles contain at least one of boron oxide, potassium pyrosulfate and a compound containing an alkali metal or Br, while having a transformation point, at which the filler particles undergo a transformation from a solid phase to a liquid phase or a thermal decomposition, within the range of from 180° C. to 650° C. The compound containing an alkali metal or Br contains at least one of a borate, a silicate, a carbonate, a hydrogen carbonate, a citrate or an aromatic compound.
