Sodium-ion Battery Cells Explained: Capacity, Format & Real Numbers
Sodium-ion batteries promise lower cost, better cold-weather performance, and freedom from lithium supply constraints — but how do their capacities actually stack up against lithium-ion? We break down real cylindrical and prismatic cell data from HiNa, CATL, and Farasis to see where sodium-ion matches lithium-ion, and where it still falls short.
