Mechanical Compression Prevents Short-Circuiting in Solid-State Batteries

Researchers from SLAC National Accelerator Laboratory and Stanford University have discovered that applying mechanical compression can prevent short-circuiting in solid-state batteries. This method deflects lithium-filled intrusions, known as dendrites, which typically cause battery failure. The findings, published in Nature, also provide direct evidence that dendrites originate within the electrolyte, resolving a long-standing debate and offering a promising approach for designing safer, more reliable solid-state batteries.
