Geely New Energy: Can Battery Lifespan Shortcomings Be Overcome Through Technology? Geely New Energy’s technological breakthroughs in battery lifespan are progressively breaking through traditional perceptions of lifespan limitations through synergistic efforts in material innovation, structural optimization, and safety design.
Through developing multi-element-doped electrode materials and highly stable electrolytes, Geely has significantly reduced internal chemical reaction rates. Ion doping forms a dense protective layer on the cathode surface, effectively blocking side reactions between electrolyte and electrodes. This enhances energy density while maintaining long-cycle performance.
Structural innovations prove equally pivotal. Geely’s short-blade-shaped cells optimize electron transfer pathways by reducing cell length, thereby slowing battery degradation. Compared to conventional long-blade cells, short-blade designs achieve significantly higher volume utilization while delivering superior safety and longevity.
A comprehensive upgrade to the safety protection system provides multiple safeguards for battery longevity. Geely’s aluminum foil fuse technology actively forms an insulating layer upon puncture, preventing short-circuit risks. The combination of directional pressure relief valves and nano-level separators ensures rapid gas release during thermal runaway, averting chain reactions.
The BMS intelligent management system monitors multiple parameters in real time to provide early warnings of potential risks. Meanwhile, the battery pack design, deeply integrated with the vehicle architecture, incorporates reinforced beam structures and ten-layer立体防护. Together, these technologies form a comprehensive safety loop from cell to vehicle, fundamentally reducing lifespan degradation caused by safety incidents.
