Chinese automotive manufacturer Geely has announced a major improvement in electric vehicle battery technology with its new ‘Short Blade Battery’. This self-developed LFP (Lithium Iron Phosphate) battery addresses key challenges faced by traditional blade batteries, offering improved performance and energy density.
The Aegis Short Blade Battery boasts impressive specifications, including an energy density of 192 Wh/kg and a rapid charging time of just over 17 minutes from 10% to 80%. Geely claims the battery can withstand 3,500 cycles without significant capacity loss, potentially extending the lifespan of electric vehicles.
The New Short Blade EV Battery is capable of lasting up to 1 million kilometers (equivalent to 3,500 charging cycles), potentially providing a lifespan of up to 50 years for average users. Furthermore, the battery retains 90.54% capacity at -30°C, compared to 78.96% for long blade batteries.
Key additional features include:
- High-strength, high-thermal stability, and high-heat-resistant diaphragm.
- Self-Fusing technology to block short circuits in case of accidents.
- Successful testing with extreme conditions, including eight-needle puncture tests and bullet penetration tests without thermal ignition.
Utilizing carbon nanotubes for enhanced ion transfer and featuring advanced safety measures, this new battery technology could debut in Geely’s upcoming Galaxy E5 electric SUV. The development marks a significant step in Geely’s efforts to innovate in-house alongside its partnerships with major battery suppliers.
As the electric vehicle market continues to evolve, Geely’s latest offering could potentially accelerate the adoption of more efficient and longer-range electric cars.
