Sodium-Ion Powered EVs Roll off From Chinese EV Factories

Get Electric Vehicle

The first mass-produced electric vehicle (EV) using a sodium-ion battery has been introduced by JAC Motors. While lithium-ion batteries are more developed and have a higher density than sodium-ion batteries, sodium-ion batteries are cheaper, dependable, and have better cold-weather performance.

IBC demonstrates highly selective high-yield direct lithium extraction from Salar de Maricunga brine

Green Car Congress

DLP Pilot Plant Phase 1 results: 99+% of lithium selectively extracted directly from Salar de Maricunga brine; lithium is below analytical detection limits in Li-depleted brine. Concentrations of key elements in the Salar de Maricunga brine are: Li (0.767 g/L), Mg (5.37 No pre-removal or concentration steps are required. m3 per day.
