<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>

宁德时代

摩根士丹利对中国电池退化的研究显示，宁德时代的电池在电动汽车（EV）和长期储能系统中表现出最小的退化。该研究分析了 100 辆电动汽车的数据，发现宁德时代在 Model 11 和 Model 12 中的电池退化率最低。在张北国家风光储示范项目的长期评估中，宁德时代的电池在 14 年后仍保持约 90% 的容量，而其他供应商则面临显著的更换。这一表现巩固了宁德时代作为全球最大电池制造商的地位

宁德时代的电池因在电动汽车和长期储能系统中表现出极小的退化而备受瞩目
