可充电锂电池作为新一代电动汽车动力系统受到了广泛关注。锂离子电池、锂硫电池和锂氧电池都适合作为下一代电动汽车的动力系统，但其功率密度和循环性能仍有待提高，以满足实际电动汽车的要求。因此，合理设计和可控合成具有独特微观结构和优异电化学性能的电极材料至关重要。多孔碳基复合材料由于其独特的性能，包括高电子导电性、高结构稳定性、高比表面积、用于高效电解质通量的大孔体积，以及在多孔碳框架限制下尺寸可控的高活性电极材料，在能量存储和转换方面具有许多优势。因此，多孔碳复合材料作为锂离子电池、锂硫电池和锂氧电池的电极材料表现出优异的性能。本文综述了可充电锂电池用多孔碳复合材料的研究进展。本文详细介绍了多孔碳复合材料在锂离子电池、锂硫电池和锂氧电池中的合成、物理和化学性质以及创新和意义。最后，我们总结了可充电锂电池商业化需要解决的前景和关键挑战。
Rechargeable lithium batteries have attracted great attention as next generation power systems for electric vehicles (EVs). Lithium ion batteries, lithium-sulfur batteries, and lithium-oxygen batteries are all suitable to be the power systems for next generation EVs, but their power densities and cycling performance still need to be improved to match the requirements of practical EVs. Thus, rational design and controllable synthesis of electrode materials with unique microstructure and outstanding electrochemical performance are crucially desired. Porous carbon-based composites have many advantages for energy storage and conversion owing to their unique properties, including high electronic conductivity, high structural stability, high specific surface area, large pore volume for efficient electrolyte flux, and high reactive electrode materials with controllable size confined by porous carbon frameworks. Therefore, porous carbon composites exhibit excellent performance as electrode materials for lithium ion batteries, lithium-sulfur batteries, and lithium-oxygen batteries. In this review, we summarize research progress on porous carbon composites with enhanced performance for rechargeable lithium batteries. We present the detailed synthesis, physical and chemical properties, and the innovation and significance of porous carbon composites for lithium ion batteries, lithium-sulfur batteries, and lithium-oxygen batteries. Finally, we conclude the perspectives and critical challenges that need to be addressed for the commercialization of rechargeable lithium batteries.
