Separator films of PE or PP which have been conventionally used oxidize and degrade. The possibility that, as a result, insulation properties are reduced or lifetime performance decreases has not been resolved. Furthermore, with conventional battery configurations, there has been a tradeoff between capacity and output so that it has been difficult to achieve high output. In an electrolyte system, there has been the problem that, as a result of temperature dependency of an electrolyte, performance at a low temperature has deteriorated so that desired performance could not be achieved. Furthermore, as a result of the expansion of specific applications, quick-recharge is being desired for recharge as well. In the separator according to the present invention, by configuring thereof so as to support a material containing ceramic material and elemental phosphorous in a nonwoven fabric, it is possible to continuously maintain insulation in a an expected environment and to improve safety. |
