#sodium-ion batteries

Cornex New Energy has introduced a 165 Ah sodium-ion prismatic cell for stationary storage, positioning the chemistry as a contender for frequency regulation and other large-scale applications.

After years in the shadow of lithium-ion technology, sodium-ion batteries are poised for commercial takeoff in 2026. Multiple manufacturers are scaling production, costs are plummeting, and the technology's advantages in safety and resource availability are making it increasingly attractive for grid storage and affordable EVs.

University of Surrey researchers have discovered that keeping water in sodium-ion battery cathodes nearly doubles their energy storage capacity. The counterintuitive finding upends conventional wisdom that water must be removed from battery materials during manufacturing.
