NEWS: Sodium-ion batteries are moving from “science project” to grid-scale reality. 🧪

  • Chinese battery giant CATL signed its first big sodium-ion deal, committing to ship 60 GWh of cells to Beijing HyperStrong over three years. It’s a signal that the industry has resolved the moisture control and energy density hurdles slowing the tech’s mass production.

  • Stateside, iron-flow leader ESS Tech is partnering with Alsym Energy to add 8.5 GWh of sodium-ion batteries to its portfolio for short- and medium-duration applications.

  • Why it matters: As lithium prices remain volatile, sodium-ion offers a cheaper alternative with a simpler supply chain (and without the thermal runaway risks). This makes it a prime candidate for fire-sensitive data centers and residential deployments.
