摘　　要：综述了有关锂空气电池所应用的碳材料的种类及其性能,总结了不同种类碳材料的物理参数,如比表面积、孔体积、粒子尺度以及电导性等对锂空气电池性能的影响规律;以及碳材料改性对锂空气电池氧电极的性能改善。已有的文献数据表明用于锂空气电池的碳材料必须具有较好的导电性、较大的比表面积、合适的孔体积和粒子尺度等。这些物理化学参数为应用于锂空气电池的碳材料的选择提供了依据。The different types and physical properties of carbon materials used in lithium-air battery field were summarized, and the influence of the various physical parameters of carbon materials on the performance of lithium air battery were discussed, such as specific surface area, pore volume, particle size and conductivity. The research progress in the modifications of carbon materials was also simply summarized. It is concluded that carbon with good electrical conductivity, large surface area, appropriate pore volume and particle size are necessary, which governs the electrochemical performance of oxygen cathode. These physical parameters can be the basic criteria for selection of carbon material as cathode material in lithium air batteries.
