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

Green Car Congress

Despite the enticing properties of lithium used as an anode material in energy storage systems—such as the extremely high theoretical capacity of 3860 mA h g -1 —practical application is still hindered by the safety issues resulting from lithium dendrite growth.

Roskill forecasts Li-ion battery demand to increase more than ten-fold by 2029 to >1,800GWh

Green Car Congress

Roskill forecasts that Li-ion battery demand will increase more than ten-fold by 2029, reaching in excess of 1,800GWh capacity. In the late 2020s, Li-ion technologies could see increasing competition from other battery technologies, though Li-ion cells are expected to maintain their dominant position, Roskill said.
