KATHMANDU: CATL has revealed details of its latest 5C ultra-fast charging long-life battery, claiming a theoretical lifespan of up to 1.8 million kilometers. The company shared the information in an official video released on January 29, 2026.
According to CATL, the new 5C battery retains 80 percent capacity after 3,000 full charge-discharge cycles under ideal conditions. This cycle life is around six times higher than the current industry average and could outlast the vehicle itself.
CATL also highlighted performance under extreme heat. At 60°C, similar to summer temperatures in Dubai, the battery reportedly maintains 80 percent capacity after 1,400 cycles, equivalent to about 840,000 kilometers. This exceeds the durability of most commercial lithium-ion batteries available today.
The 5C rating means the battery can be fully charged in around 12 minutes. CATL says achieving this required improvements in structural stability and thermal safety during ultra-fast charging.
The company credits three key technologies for the longer life. These include a more uniform cathode coating to reduce degradation, a proprietary electrolyte additive that repairs microcracks and limits lithium loss, and a temperature-responsive separator coating that slows ion movement when heat rises, reducing thermal risk.
CATL has also upgraded the battery management system. The new system can actively direct coolant to hotspots inside the battery pack, improving temperature control and extending overall lifespan.
The new 5C battery targets high-usage segments such as electric trucks, taxis, and ride-hailing vehicles to reduce total lifecycle costs.
