As electric vehicles become increasingly popular, demand for key battery ingredients, particularly cobalt, has spiked. That has spurred car and battery makers to seek alternatives to the current three main technologies — nickel-cobalt-aluminium (NCA), nickel-cobalt-manganese (NCM) and lithium iron phosphate (LFP) batteries.
The sodium-ion batteries do not contain lithium, cobalt or nickel. CATL did not disclose cost details of the new batteries.
China’s top car battery maker, with a market value of almost $200 billion, also unveiled a battery pack that integrates sodium-ion and lithium-ion batteries.
The energy density of its new sodium-ion batteries is still lower than that of LFP batteries, Huang Qisen, deputy head of CATL’s research center told an online briefing. But he added
