- CATL signs a three‑year 60 GWh sodium‑ion battery supply agreement with HyperStrong, matching half of its 2025 energy‑storage shipments.
- HyperStrong secures the largest sodium‑ion order ever, building on a 200 GWh framework signed in Nov 2025 for deliveries from 2026‑2035.
- BYD unveils a third‑generation sodium‑ion platform delivering over 10 000 cycles and solved high‑temperature performance, showing rivals are closing the gap.
- Sodium‑ion cells from CATL offer 300 Ah capacity, 160 Wh/kg energy density, 97 % round‑trip efficiency, and operate from –40 °C to 70 °C, enabling plug‑and‑play grid integration.
Why it matters: Grid operators secure 60 GWh of low‑cost sodium‑ion storage, cutting battery spend by up to 30 % and enabling faster renewable‑energy integration, reducing reliance on fossil‑fuel peaker plants.
