ABSTRACT:
An electrolyte with high ion conductivity, a process for producing the same and a battery using the same, and a compound for the electrolyte. The electrolyte is set between a negative electrode and a positive electrode. The electrolyte includes a first polymer compound, a second polymer compound and light metal salt. The first polymer compound has a three-dimensional network structure formed by bridging bridgeable compounds with the bridge groups, which contributes to the high mechanical intensity of the electrolyte. The second polymer compound has no bridge groups and dissolves light metal salt. Each of the first and the second polymer compounds has an ether bond. The first and the second polymer compounds form a semi-interpenetrating polymer network, and achieve higher ion conductivity than that of each polymer compound.
