A dash of salt
Nature Energy, Published online: 05 February 2025; doi:10.1038/s41560-025-01706-yImproving the solid–electrolyte interface at the lithium-metal interface is key to stabilizing rechargeable metal batteries. Now, stabilizing the cathode electrolyte interface through molecular optimization of the salt anion is shown to support the formation of a robust inorganic polymer and conductive interface, enabling high energy and power densities at various current densities and temperatures.
