CATL’s 30-year sodium-ion battery takes over grid storage

CATL has signed a memorandum of understanding with Dutch energy company Alfen to deploy 5 GWh of its Tener Sodium energy storage systems across Europe, one of the largest sodium-ion commitments the region has seen.

The batteries are rated for 15,000 cycles and a 25-to-30-year service life — the pitch that sodium-ion’s longevity, not its energy density, is what wins grid storage.
