Description
固体状電解質は、二次電池の設計において、力学的安定性、不揮発性、および易構築性を含む多くの利点を提供する。既存の、高いイオン伝導率を示す無機固体状電解質は、通常は硬質材料であり、こうした材料は、電池サイクル中において、はっきり認められる程度の電極材料との接触を維持することができない。ポリマーのような有機固体状電解質は、硬度が低いため、このような問題を克服できるが、イオン伝導率が低いという問題がある。
二次電池のための軟質固体電解質の合成および最適化方法が提供される。
本発明の教示によって、固体状にて高いイオン伝導率を有する軟質電解質組成物の合成および最適化方法が提供される。軟質電解質組成物は、典型的には電池動作温度において固体であるが、高エントロピーでプラスチック様の分子構造をもつために、通常にはない程度の高いイオン伝導率を有する。
