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.

HIU researchers develop extremely high energy density lithium-metal cell with good stability

Green Car Congress

The team used a a promising combination of cathode and electrolyte: the nickel-rich cathode allows a large amount of energy per mass to be stored, while the ionic liquid electrolyte ensures that the capacity is largely retained over many charging cycles. The team reports on the lithium metal battery in an open-access paper in Joule.
