These small, unevenly branched crystalline structures form on the lithium-metal electrode during charging, which shortens the battery’s lifespan and exposes it to the risk of a short circuit. This discovery was made when scientists developed a new “cohesion inhibitor” liquid that ensures lithium ions deposit evenly on the surface of the positive electrode, thereby inhibiting the formation of branches, according to the newspaper. This research paves the way for electric cars capable of fast long-distance travel, making them more practical and appealing for both regular drivers and long road trips.
