The aim of the project is an economically viable design for “all-solid-state” rechargeable batteries. Eliminating organic liquid electrolytes from lithium-ion batteries will dramatically increase safety, range of operating conditions, lifetimes, and energy density. The key technical challenge is keeping solid-solid interfaces intact over thousands of charge/discharge cycles. We will address this by inserting inorganic interfacial layers that change smoothly from hard ceramic to flexible glass and back again, through rigorous chemical design and synthetic control. This will reduce the stress that causes mechanical failure, while increasing chemical stability so that the latest generation of high-power electrodes can be brought into service.

该项目的目标是为“全固态”可充电电池设计一种经济可行的设计。从锂离子电池中去除有机液体电解质将大大提高安全性、工作条件范围、使用寿命和能量密度。关键的技术挑战是在数千次充电/放电循环中保持固体-固体界面的完整。我们将通过插入无机界面层来解决这个问题，通过严格的化学设计和合成控制，无机界面层可以从硬陶瓷平滑地转换为柔性玻璃，然后再转换回来。这将减少导致机械故障的应力，同时增加化学稳定性，从而使最新一代的高功率电极可以投入使用。
