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.

The 80-20 Rule

Plug In Partners

So why carry around five times more battery storage and weight for that 20 %? Two reasons: (1) Electric motors are extremely efficient compared to internal combustion engines, and this efficiency more than compensates for the dirtiness of coal. (2) Are the batteries ready? And the remaining 20% are longer trips. 2) The U.S.
