锂离子电池无钴正极材料的研究

Research on cobalt free cathode materials for lithium ion batteries

锂离子电池因其具有高能量密度,几十年来一直垄断着便携式电子产品和电动汽车的储能市场。然而,领先的电池制造商正试图通过减少对正极材料中钴的依赖来降低制造成本。本文通过回顾新型无钴正极的背景、发展现状和面临的挑战,探讨了发展锂离子电池无钴正极材料需要考虑的几个方面。最后,从实际出发,展望了锂离子电池无钴正极的研究方向。

In recent decades,lithium-ion batteries have dominated the energy storage market for portable electronics and electric vehicles,among others,because of their high energy density.However,leading battery manufacturers are trying to reduce manufacturing costs by reducing their reliance on cobalt in cathode materials.By reviewing the background,current development status,and challenges faced by several new cobalt-free anodes,this paper discusses several aspects that need to be considered for the development of cobalt-free anode materials for lithium-ion batteries.Finally,the research direction of cobalt-free anode for lithium-ion batteries is envisioned from a practical point of view.
