CATL Shares Details Of Next Generation 5C Battery - CleanTechnica

CATL has unveiled details of its next-generation 5C battery, which significantly advances rapid charging and battery longevity for electric vehicles (EVs). The 5C rating means the battery can theoretically be charged at five times its capacity rate, enabling a full charge in about 12 minutes with a 400 kW charger, compared to the typical slower charging rates currently experienced. This new battery reportedly offers about six times the life expectancy of current industry averages, potentially outlasting the vehicle itself. Under extreme heat conditions (60°C), it maintains 80% capacity after 1,400 cycles, equivalent to roughly 840,000 kilometers, far surpassing conventional lithium-ion cells. CATL attributes these improvements to three key innovations: a denser and more uniform cathode coating that reduces structural degradation, a proprietary electrolyte additive that repairs micro-cracks and reduces lithium loss, and a temperature-responsive coating on the separator that slows ion migration to prevent thermal runaway. Additionally, an upgraded cooling system targets hot spots
