A commercial sodium-ion battery already used in China is moving into Tesla-like territory, putting fresh pressure on lithium-ion’s cost advantage. Researchers testing Hina’s cells found consistent output across a large sample, high power capability, and a design that echoes key choices in Tesla batteries. The low-cost sodium battery still has work ahead, especially around charging in freezing conditions, but it points to a cheaper path for EVs, grid storage, and commercial vehicles that don’t need maximum driving range.
