In China, lithium manganate has been widely used in low-end and cottage, and LFP has been hyped for several years. However, in recent years, with the clarity of domestic trends and EV benchmarking effect in Japan and South Korea, some fairly enlightened domestic enterprises have begun to pay attention to the research and development and application of high-end lithium manganate. In fact, if we only study lithium manganate, we have studied the performance of modified lithium manganate represented by Qingdao Xinzheng Lithium Industry for decades, which is not worse than that of Japan and South Korea. 20 1 tested manganese batteries all use their lithium manganate, but there is still a big gap in the development of domestic battery system, especially the follow-up of supporting electrolyte. It is believed that with the development of lithium battery technology, the advantages of lithium manganate will also appear in China, but now the biggest challenge of lithium manganate in China is the domestic hype environment and fierce price war besides battery performance.
