The start-ups hoping to return battery making to the US
New American start-ups are attempting to revitalize domestic battery manufacturing by focusing on emerging sodium-ion technology. Companies like San Diego-based Unigrid are scaling up production to meet surging international and domestic demand driven by extreme weather events and high energy costs. Unlike traditional lithium-ion cells, sodium-ion batteries promise to be cheaper, safer, and capable of operating in extreme temperatures. However, US firms face fierce competition from global leaders like China and must overcome historical industry hurdles to achieve fully localized supply chains.
