Energy storage made from sodium could be produced in the United States

Battery cells that rely on sodium ions can be manufactured within the United States. These units rely on sodium, a common element, to carry their electric charge.

Makers can build these devices using materials found directly inside the country. Getting resources from domestic sources means builders do not need to rely on foreign mineral supplies.

The available details do not name the firms working on this method or when production might start. It is also unclear how the price and performance of these units compare with older designs.
