To solve the problems of low safety, high internal resistance, and poor high-rate charging/discharging properties, problems which are caused by low heat resistance and low voltage collapse resistance, a battery electrode surface or separator surface protective agent composition containing at least two types of organic particles obtained from substantially incompatible organic matter, having fluidity, and being capable of being cured and formed by a hot melt, is characterized by, when curing and forming the composition, the organic particles of the same type heat-sealing with one another and forming a continuous phase. |
