A sodium-ion battery developed in China has achieved a significant milestone, operating safely up to 300 °C without smoke or fire. This technology maintains an energy density of 211 Wh/kg and functions reliably in temperatures from -40 °C to 60 °C.
It effectively prevents thermal runaway, even under mechanical stress. Projections indicate that sodium-ion batteries may reach cost parity with lithium batteries by 2027, improving competitiveness in sectors like automotive and energy storage.
Initial tests show a 15% reduction in energy consumption for electric trucks and an approximate 20% increase in range compared to traditional options. The technology is being commercialized by HiNa Battery, a spin-off from the Chinese Academy of Sciences, with rapid transitions from lab to production.
