New strategy for dendrite-free Li-metal batteries based on atomic channels

Green Car Congress

An international team of researchers has developed a new strategy for dendrite-free lithium-metal batteries based on the use of interlayer and intralayer atomic channels in graphite formed by pre-tunnelling the graphite layers. The obtained atomic channels enable the free and fast diffusion of lithium with enhanced kinetics. atomic channels.
