High-capacity alloy metal-ion battery anodes suffer from rapid failure due to the phase transformations that occur through reversible alloying reactions during charging and discharging. These phase transformations give rise to large mechanical stresses and huge volume changes that ultimately lead to battery failure after just a few charge-discharge cycles. In this talk, I will demonstrate the use of a new “self-healing” approach based on solid-liquid phase transformations in fusible alloys during charging and discharging to overcome these issues in sodium-ion and magnesium-ion battery anodes .
