期の粘度を維持していることが型費な要因と考えられる
。The reason why the battery of the present invention has excellent discharge characteristics at low temperatures after storage is based on the results in the table above. While 2-methyldioxolane gels during storage, increasing its viscosity and decreasing its conductivity, the methyl group of 2-methyldioxolane acts as a steric hindrance, preventing gelation from proceeding and maintaining its initial viscosity. This is thought to be a cost factor.
