Overview
- Company data says the 5C lithium‑ion cell retains about 80% capacity after 3,000 fast‑charge cycles at roughly 20°C, equating to around 1.1 million miles.
- CATL also reports 80% capacity after 1,400 cycles at 60°C, a level the company likens to very hot climates, or roughly 520,000 miles of use.
- The 5C designation reflects an ultra‑fast charge rate that, in theory, can refill a pack from empty in about 12 minutes.
- CATL attributes the durability to materials and control advances, including a uniform cathode coating, an electrolyte crack‑repair additive, a temperature‑responsive separator, and targeted cooling via the BMS.
- Media coverage notes these are company‑released laboratory results, and CATL has not disclosed mass‑production plans or vehicle integrations.
