The first electrolyte (green) is more stable with lithium but prone to dendrite penetration. The second electrolyte (brown) is less stable with lithium but appears immune to dendrites. This design allows dendrites to grow through the graphite and first electrolyte but are stopped when they reach the second.
Adding an extra layer of tomato on a metaphoric BLT could be the solution to a decades-long problem that has prevented scientists from developing the solid-state lithium batteries that would significantly increase the range and lessen the charging time of electric vehicles.
For roughly 40 years, researchers have tried to harness the potential of solid-state, lithium-metal batteries, which hold...
