Overview
- CATL, which announced the agreement Monday, will supply 60 GWh of sodium‑ion batteries to Beijing HyperStrong over three years.
- HyperStrong becomes CATL’s first strategic partner for sodium‑ion in battery energy storage, with joint work on R&D, product use, and project rollouts.
- CATL says it can now mass-produce sodium‑ion cells after solving energy‑density limits and fixing manufacturing issues like foaming and moisture control.
- Reporters called it the largest sodium‑ion order to date, and Electrek noted the volume equals about half of CATL’s 2025 energy‑storage shipments.
- Sodium‑ion swaps lithium for abundant sodium, which experts say could lower costs, and Electrek reported CATL kept the same cell size as lithium‑ion to help customers adopt the tech faster.
