This project aims to engineer electrolyte materials, based on organic ionic plastic crystals, and use isomeric doping to improve the ionic conductivity. The development of safer batteries relies on eliminating the volatile and flammable solvents commonly used as the electrolyte. Improving the safety and performance of batteries is important as electricity costs increase. Solid state ionic electrolytes can address leakage and volatility problems, but the conductivity must be improved if these materials are to support high battery power. The project’s electrolyte materials can be used in lithium metal batteries, which have higher theoretical energy densities than traditional lithium ion batteries. This project will develop new solid state electrolytes, with improved conductivity, and use these materials in emerging lithium battery technologies.

本项目旨在设计基于有机离子塑料晶体的电解质材料，并使用异构掺杂来提高离子电导率。更安全电池的开发依赖于消除通常用作电解质的挥发性和易燃溶剂。随着电力成本的增加，提高电池的安全性和性能非常重要。固态离子电解质可以解决泄漏和挥发性问题，但如果这些材料要支持高电池功率，则必须提高导电性。该项目的电解质材料可用于锂金属电池，其理论能量密度高于传统锂离子电池。该项目将开发具有更高导电性的新型固态电解质，并将这些材料用于新兴的锂电池技术。
