Chemical Breakthrough Could Unlock the “Holy Grail” of Solid-State Battery Technology

A simple chemical treatment could overcome a persistent weakness in next-generation solid-state batteries. Scientists in China have developed a thin protective coating that could help overcome a major obstacle to longer-lasting, high-capacity batteries. In laboratory tests, solid-state batteries using the treated lithium metal retained 82.3% of their initial capacity after 300 charging cycles, compared with [...]
