✅ Low-Temperature Sodium-Ion Battery: Industry-first, retaining 90% of its capacity at -40℃, completely solving the problem of vehicles "stalling" in northern winters. No preheating required, just plug in and go.
✅ 200Wh/kg Energy Density: Currently the highest in the light commercial vehicle sector. For the same amount of power, the battery pack is smaller and lighter, reducing the overall vehicle weight by up to 300kg, meaning you can carry an extra ton of cargo while consuming less electricity.
CTP3.0 Module-Free Extreme Packaging Technology
Eliminates traditional module structures, integrating battery cells directly into the battery pack, increasing space utilization by 15%, resulting in a more compact structure and stronger impact resistance.
Dual-Layer Large-Area Liquid Cooling System
The battery pack is cooled on both the top and bottom surfaces, controlling the temperature difference within ±2℃, ensuring more even heat dissipation during charging and extending battery life by more than 30%.
Biomimetic Self-Repairing SEI Film + Low Lithium Consumption Graphite Anode
Mimics the self-repair mechanism of biological cells, reducing lithium-ion loss during charging, increasing cycle life by 100%, and maintaining over 80% capacity after 800,000 kilometers.
Aerospace-Grade Thermal Insulation Material + No Thermal Diffusion Technology
Even if a single cell experiences thermal runaway, it will not spread to the entire pack. It has passed the strictest national standard "bottom collision + short circuit after fast charging cycle" dual safety test, ensuring no fire and no explosion.
The Tianxing II battery is mass-produced upon launch and has been fully installed in vehicles. 13 car manufacturers have adopted this battery, and 21 models are already equipped with it. Foton Motor Kaven Lutu (Unveiled at the Wuxi G7 Logistics Conference)
SRM E3 Series Light Truck (First Batch of Mass-Produced Models)
Mainstream light truck brands such as JAC Motors, DFL, Geely Automobile, QINGLING Motors, Shaanxi Automobile, Changan Kuayue, and SAIC Motor Yuejin have all completed adaptation.
