Abstract:

As an aromatic polymer with abundant reserves in nature, lignin is rich in hydroxyl, carboxyl, ether and other functional groups in its structure. These functional groups can make lignin through simple and mild chemical activation to prepare porous carbon materials. Such carbon materials usually have large specific surface area and porous structure, which is conducive to sulfur loading and electrolyte penetration. Lithium-sulfur (Li-S) batteries show high theoretical specific energy, environmental friendliness, low cost and other advantages, so it is regarded as one of the most potential alternative batteries beyond the energy density limit of lithium-ion batteries. In this paper, the preparation methods of lignin-based polyporous carbon and its application in lithium-sulfur batteries were reviewed. The effects of different characteristics of lignin-based polyporous carbon in structure, composition and design on battery performance were discussed. The future application prospects of lignin-based carbon materials were also prospected.

Key words: lignin, activated carbon, composite material, lithium-sulfur battery

摘要:

木质素作为自然界储量丰富的芳香族高聚物,其结构中富含羟基、羧基、醚基等多种官能团,这些官能团可以使木质素通过简单温和的化学活化制备多孔炭材料,该炭材料通常具有较大的比表面积和多孔结构,有利于硫的负载和电解液的渗透。由于锂硫(Li-S)电池展现出高理论比能量、环境友好、成本低廉等优势,它被看作是超越锂离子电池能量密度极限的最有潜力的备选电池之一。本文综述了木质素基多孔炭的制备方法以及在锂硫电池中的应用,并对木质素基炭材料的未来应用前景进行了展望。
