We present a new concept to alter the lithiophobic nature of solid electrolytes through the creation of an ultra-wettable interface utilizing liquid metal. It can accomplish sufficient and intimate interface contact between solid electrolytes and Li metal without void formation at the atomic scale, thus promoting the diffusion of Li at the interface. The solid-state batteries exhibit superior cycling stability and rate performance without dendrite growth.

用于高度耐用的固态锂电池的超可湿液态金属界面

我们提出了一种新概念,通过利用液态金属创建超可湿界面来改变固体电解质的疏石性质。它可以在原子尺度上实现固体电解质与锂金属之间充分且紧密的界面接触,而不形成空隙,从而促进界面处锂的扩散。固态电池表现出优异的循环稳定性和倍率性能,且没有枝晶生长。
