煤基高功率锂离子电池石墨负极材料研究

Researches on coal-based graphite anode materials for high power lithium-ion batteries

双碳目标推动下,为进一步满足电动车市场的需求,研究低成本高功率的锂离子电池负极材料十分重要。通过对低成本高功率煤基锂离子电池石墨负极材料进行包覆,展开全电池容量、库仑效率、循环性能等测试,对材料的包覆效果进行了详细讨论,旨在进一步促进行业高功率锂离子电池石墨负极材料的研发。

Driven by the goal of"carbon peak and neutrality",it is extremely important to study the low-cost and high power lithium-ion battery anode materials in order to meet the needs of electric vehicle market further.The low-cost and high power coal-based lithium-ion graphite anode materials were coated and the capacity,coulomb efficiency and cycle performances were researched by the full battery testes.The coating effect on the material was discussed in detail to promote the development of graphite anode materials for high power lithium-ion battery further.
