Low-cost sodium batteries are already reaching Tesla performance levels in China
A new sodium-ion battery technology in China is approaching the performance levels of Tesla's lithium-ion batteries. This development could challenge the cost advantages of lithium-ion batteries in electric vehicles and other applications. However, the sodium battery still requires improvements, particularly in cold weather charging capabilities.
- ▪The sodium-ion battery has shown consistent output and high power capability in tests.
- ▪Its design incorporates key features similar to those found in Tesla batteries.
- ▪The technology presents a potentially cheaper alternative for electric vehicles and grid storage.

Opening excerpt (first ~120 words) tap to expand
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.
