優れている。Polyether is preferably used as the ionically dissociable salt-soluble polymer, and polyethylene oxide is particularly suitable. Many polyether μ such as polyethylene oxide crystallize around room temperature, and therefore have extremely low ionic conductivity at temperatures below room temperature. As a method for preventing crystallization of polyether, there is a method of mixing a second polymer that is compatible with polyether. This is due to the effect that the molecular chains of the second polymer and the molecular chains of boliate invade each other and make it difficult for boliate/L/gl to approach each other. At this time, it is necessary that the interaction between the polyether and the second polymer is not too strong. Certain hydrocarbon polymers are compatible with polyate ρ and have weak interactions, so tpJ2
●Hydrocarbon polymers that can be suitably used as polymers include polyethylene and bolide, but low-density polyethylene is the best in terms of compatibility.
