Sodium-Ion Storage Gains Ground

Sodium-ion batteries are moving from a prospective alternative to lithium-ion toward commercial grid-storage applications, with CATL introducing its TENER system and Peak Energy planning a U.

S. manufacturing facility. The technology is being promoted for its use of abundant materials and potential cost and safety advantages, while demand is increasing as renewable generation and electricity use from data centers place new requirements on the grid. Development remains uneven, however, with the closure of U.S. specialist Natron contrasting with China’s stronger commercial momentum and raising supply-chain concerns.
