<div id="readability-page-1"><div> Morgan Stanley decided to do some research on battery degradation in China. It got data from ride-hailing firms on 12 different EV models — 100 cars in total — and measured how much their battery capacity declined. The cars showed considerable differences in battery degradation. The company also studied degradation of batteries at a long-term, large-scale energy storage. It’s not clear what EV models were tested, but one thing was clear from the research: CATL batteries rock. The two models with CATL batteries showed the slowest degradation rates. They are Model 11 and Model 12 in the graph below. <img height="480" src="https://imageproxy.pbkrs.com/https://cleantechnica.com/wp-content/uploads/2026/01/EV-battery-degradation-study-Morgan-Stanley-graph.png?x-oss-process=image/auto-orient,1/interlace,1/resize,w_1440,h_1440/quality,q_95/format,jpg" width="795" original-src="https://imageproxy.pbkrs.com/https://cleantechnica.com/wp-content/uploads/2026/01/EV-battery-degradation-study-Morgan-Stanley-graph.png"/> In the long-term energy storage evaluation, Morgan Stanley examined batteries at the Zhangbei National Wind–Solar–Storage Demonstration Project (one of the first large-scale energy storage systems in China). ESPLAZA LDES Network summarizes CATL’s leadership as follows: “Among four LFP battery suppliers involved: <ul> <li>Only CATL batteries have never been replaced</li> <li>After 14 years of operation, capacity remains at approximately 90%</li> <li>Other suppliers experienced large-scale replacements or early retirement”</li> </ul> That looks like a huge difference. Perhaps this is one key reason CATL has become the largest battery maker in the world — a reputation for high-quality, long-lasting batteries. </div></div>

寧德時代

摩根士丹利對中國電池退化的研究顯示，寧德時代的電池在電動汽車（EV）和長期儲能系統中表現出最小的退化。該研究分析了 100 輛電動汽車的數據，發現寧德時代在 Model 11 和 Model 12 中的電池退化率最低。在張北國家風光儲示範項目的長期評估中，寧德時代的電池在 14 年後仍保持約 90% 的容量，而其他供應商則面臨顯著的更換。這一表現鞏固了寧德時代作為全球最大電池製造商的地位
