【摘要】 近年来,随着便携式电子电气设备的发展,人们对锂离子电池负极的储锂性能和循环稳定性等有了更高的要求。石墨作为目前商业化程度最高的锂离子电池负极材料,有着成本低、性能稳定、环境友好等优点,但同时也存在比容量低、石墨片层剥落削减使用寿命等缺点,不足以满足新一代高能量新能源设备的要求。为解决这一问题,研究学者们在对以石墨为主导的负极进行改性的同时,也探索着硅基、锡基、过渡态金属化合物等大容量、高性能材料在锂离子电池负极的应用。在高能球磨法的基础上,综述其在锂离子电池负极储锂材料改性中的应用研究进展,提出高能球磨法在改性锂离子电池负极储锂材料领域的应用建议,并对锂离子电池负极改性技术的发展趋势进行展望。更多还原

【Abstract】 In recent years, with the development of portable electronic, people have higher requirements for the lithium storage performance and cycle stability of the negative electrode of lithium-ion batteries. Graphite is currently the most commercialized anode material for lithium-ion batteries. It has the advantages of low cost, stable performance, environmental friendliness. However, it also has a low specific capacity, the service life reduction caused by graphite lamellar peeling and other shortcomings, which are not enough to meet the requirements of a new generation of high-power new energy equipment. Researchers have also explored the use of silicon-based, tinbased, transition metal compounds and other large-capacity and high-performance materials in lithium batteries application of negative electrode to solve the problem while researching the modification of graphite-led negative electrodes. Its application research progress is summarized in modifying lithium-ion battery negative electrode lithium storage materials based on the high-energy ball milling method.Applying a high-energy ball milling method is propased to prepare lithium-ion battery negative electrode lithium storage materials. The development trend of lithium ion battery anode modification technology has been prospected.更多还原
