Electrochemical corrosion accompanies dendrite growth in solid electrolytes - Nature

Nature, Published online: 25 March 2026; doi:10.1038/s41586-026-10279-zOperando birefringence microscopy measurements of the stresses around growing dendrites in solid electrolytes show that stresses decrease as current densities increase, revealing a linkage between electrochemical and mechanical stability that informs the design of solid-state batteries.
