CATL Batteries Stand Out For Minimal Degradation In EVs And Long-Term Energy Storage Systems - CleanTechnica

Morgan Stanley conducted research on battery degradation in China by analyzing data from 100 electric vehicles across 12 models used by ride-hailing firms. The study revealed significant differences in battery capacity decline among the vehicles, with two models equipped with CATL batteries exhibiting the slowest degradation rates. Although the specific EV models tested were not disclosed, CATL’s batteries clearly outperformed others in terms of longevity. Additionally, Morgan Stanley evaluated long-term battery performance at the Zhangbei National Wind–Solar–Storage Demonstration Project, a pioneering large-scale energy storage system in China. Among four lithium iron phosphate (LFP) battery suppliers, only CATL’s batteries maintained about 90% capacity after 14 years without needing replacement, while competitors faced large-scale replacements or early retirements. This durability likely contributes to CATL’s position as the world’s largest battery manufacturer, known for producing high-quality, long-lasting batteries.
