After 2 million kilometers (1.25 million miles), CATL’s EV batteries retained about 400 km (250 mi) of range. Competitor cells, on the other hand, retained considerably less, at around 350 km (218 mi) and less.
For example, CATL is one of four LFP battery suppliers at the Zhangbei National Wind-Solar-Storage Demonstration Project in China. CATL’s batteries are the only ones that have never been replaced, retaining over 90% of residual capacity after 14 years.
CATL was also the first to deploy an LFP battery with more than 12,000 cycles in Jinjiang in 2020. The system it’s used in is expected to last over 20 years at 1.5 to 2 cycles per day.



It should be possible to discharge more power with a V2H / V2G charger.
