CATL has made a significant advancement in lithium metal batteries (LMB) by doubling their lifespan while achieving an energy density of 500 Wh/kg. This development comes from using a new lithium salt for the battery electrolyte, which is crucial for enhancing battery performance. Though this leap brings LMBs closer to commercial viability for electric vehicles and aviation, challenges remain in balancing energy density and longevity. The research indicates the electrolyte's role is pivotal, as previous LMB prototypes suffered from rapid electrolyte consumption, leading to a short lifespan.
This breakthrough emphasizes the significant role of innovative electrolytes in enhancing battery performance, crucial for the future of efficient energy storage.
By incorporating LiFSI, CATL has shown that electrolyte composition can dramatically influence the lifespan and efficiency of lithium metal batteries.
