New Battery Offers 50-Year Service Life and 3,500 Charge Cycles

Geely, the Chinese automotive giant, has unveiled a revolutionary lithium iron phosphate (LFP) battery cell with impressive features, including a 50-year service life and 3,500 charge cycles. This breakthrough technology promises to address several longstanding concerns about electric vehicle (EV) batteries, enhancing performance, longevity, and reliability.¹

Unmatched Durability and Lifespan

Geely’s new LFP battery boasts a remarkable energy density of 192 Wh/kg, allowing it to maintain performance over more than 600,000 miles, equating to approximately 50 years of service life based on average annual driving distances. This longevity is a significant advancement, promising to extend the lifespan and resale value of used EVs.²

Rapid Charging Capability

One of the standout features of this battery is its rapid charging ability. Thanks to the adoption of carbon nanotubes and enhanced cover film, the battery can charge from 10% to 80% in just 17 minutes. This impressive efficiency is achieved by accelerating lithium ion movement, making it highly competitive in the fast-evolving EV market.³

Resilience in Extreme Conditions

Geely’s Aegis Short Blade Battery also excels in extreme conditions, experiencing only a 10% range loss in extremely cold environments. This resilience matches that of CATL’s fast-charging LFP cell introduced last year, ensuring reliable performance even in harsh climates.

Rigorous Testing and Safety

To guarantee its durability, Geely subjected the battery to rigorous tests, including exposure to open flames, puncturing with nails, rolling over, submersion in corrosive seawater, and operation in freezing conditions. The battery’s thermally resistant separator and self-healing electrode technology passed all tests with flying colors, setting a new standard for EV safety.

Deployment and Future Plans

Initially, Geely plans to deploy the new LFP cells in their Galaxy E5 SUVs before making them available to other customers. This strategic approach allows Geely to refine the technology based on real-world usage before broader distribution.

Market Implications

This innovative battery technology is expected to significantly boost the resale value of used EVs, as the enhanced durability ensures minimal capacity loss over extended periods. Additionally, the reduced internal resistance and efficient ion transfer make the battery a promising candidate for a wide range of EV applications.

Conclusion

Geely’s new LFP battery represents a significant leap forward in EV technology, offering unmatched durability, rapid charging, and resilience in extreme conditions. This innovation not only enhances the viability of electric vehicles but also addresses long-standing concerns about battery lifespan and performance, paving the way for more sustainable and reliable transportation options.
