In article number 2000960, Yang Jin, Hui Wu, Yi Cui, and co-workers design a garnet-type Li6.4La3Zr1.4Ta0.6O12 solid-electrolyte-based molten lithium–molybdenum–iron(II) chloride battery. Different from the conventional reaction mechanism of batteries, this battery synchronizes the reversible Fe–Mo alloying–dealloying reactions with the delithiation–lithiation processes, meaning that the porous Mo skeleton derived from the dealloying reaction can suppress the growth of pure Fe particles. This approach is promising for other alkali metal–metal chloride battery systems.
