New paper published in Matter

Our paper “Operando Analysis of the Molten Li|LLZO Interface: Understanding How the Physical Properties of Li Affect the Critical Current Density” is published in Matter. We show that solid-state batteries (SSBs) using high-temperature (molten) Li metal anodes can withstand extremely high current densities of 530 mA/cm2, which is an order-of-magnitude higher than achievable with solid Li. Using a combination of optical and electron microscopy, we probe the failure mechanisms of molten Li metal anodes. These results highlight the critical role of the mechanical properties of Li metal on SSB interfaces. [link]
