摘要
自双碳目标出台后,新型能源在能源消耗结构中的占比迅速提高,锂离子电池(LIBs)储能市场也稳步发展,而正极作为电池性能提升的关键性因素更是受到了国内外的广泛关注。在应用于电动汽车领域的锂离子电池中,磷酸铁锂和三元NCM正极占据了绝大部分市场比例,二者在未来市场中的优劣势也备受争议。本文介绍了NCM三元正极材料的结构、性能、改性研究以及成本构架,并将其与磷酸铁锂进行成本、安全性、电化学性能对比,分析了未来市场中NCM三元正极的发展趋势与前景。
Since the introduction of the dual carbon target, the proportion of new energy in the energy consumption structure has increased rapidly, and the lithium ion battery(LIBs) energy storage market has also developed steadily. As a key factor for battery performance improvement, the positive electrode has attracted extensive attention at home and abroad. In the lithium-ion batteries applied in the field of electric vehicles, lithium iron phosphate and terpolymer NCM anode occupy the majority of the market proportion, and their advantages and disadvantages in the future market are also controversial. In this paper, the structure,performance, modification and cost framework of NCM ternary cathode materials are introduced, and the cost, safety and electrochemical performance of NCM ternary cathode materials are compared with lithium iron phosphate, and the development trend and prospect of NCM ternary cathode in the future market are analyzed.
