All-solid-state lithium metal battery based on three-dimensional structural design
Stanford researchers at the Cui Lab have adopted for the first time, a 3D porous lithium (Li) metal anode and flowable interphase to construct an all-solid-state Li metal battery. The flowable interfacial layer can accommodate the interfacial fluctuation and guarantee excellent adhesion at all time, while the 3D Li significantly reduces the interfacial fluctuation from the whole electrode level (tens of micron) to local scale (submicron) and also decrease effective current density for high capacity and high power operation. As a consequence, greatly improved electrochemical performance compared to the conventional Li foil counterpart can be achieved in both symmetric and full cell configuration, which is among the best reported values in the literature. This approach addresses the current challenges in creating commercially viable all-solid-state Li metal batteries for next-generation energy storage.
