Sodium-ion batteries go mainstream – pv magazine Australia

From pv magazine 01/2022Sodium-ion (Na-ion) batteries offer superior environmental credentials, enhanced safety, and better raw material costs than lithium-ion (Li-ion). In addition, Na-ion batteries also promise strong performance and continuous improvements in density and cycle rate are making the chemistry particularly exciting.“Sodium-ion technology is still in its infancy but represents a viable alternative to Li-ion technologies, depending on how far companies are willing to invest,” says Max Reid, research analyst at Wood Mackenzie. And alternative battery technologies that use fewer or zero critical raw materials could ease the growing strain on Li-ion supply chains.Sodium is a thousand times more abundant than lithium and there is practically an infinite supply of it, with the overall cost of extraction and purification far lower. Generally, Na-ion cells are quoted to…
