石墨烯在储能领域应用现状及展望
摘要:石墨烯是一种力学性能、电学性能及导热性能优异的二维材料，可提高能源利用率，是新能源、智能电网发展的有效助力。介绍了石墨烯产业的发展现状及其用作储能材料的优势与劣势，重点探讨了石墨烯材料在锂离子电池与超级电容器领域的应用以及石墨烯制备技术现状，在此基础上对石墨烯在储能领域的应用前景进行了展望。石墨烯的规模化制备技术、工艺装备和产品质量均取得阶段性突破，但是石墨烯规模化制备技术成熟度依然较低，存在不同批次石墨烯产品质量、性质差异较大的普遍问题。煤制石墨烯已经实现了工程应用，不同的应用场景对石墨烯的结构、性能要求不同，可针对不同的需要做针对性的研究，研发适用于特定应用场景的石墨烯材料。煤制石墨烯电极材料的电化学特性的研究以及煤制石墨烯基锂离子电池、超级电容器是未来研究的另一重点方向。
Abstract：Graphene is a two-dimensional material with excellent mechanical properties, electrical properties and thermal conductivity, which can improve energy utilization and is an effective boost for the development of new energy and smart grids. The development status of the graphene industry and its advantages and disadvantages as energy storage materials are introduced. The application of graphene materials in the field of lithium-ion batteries and supercapacitors and the current status of graphene preparation technology are mainly discussed. On this basis, the application prospect of graphene in the field of energy storage is prospected. Graphene's large-scale preparation technology, process equipment and product quality have achieved staged breakthroughs. However, the maturity of graphene's large-scale preparation technology is still relatively low, and there are common problems of different quality and properties of different batches of graphene products. Coal-made graphene has already achieved engineering applications. Different application scenarios have different requirements on the structure and performance of graphene. Targeted research can be done for different requirements to develop graphene materials suitable for specific application scenarios. The research on the electrochemical characteristics of coal-made graphene electrode materials and the coal-made graphene-based lithium-ion batteries and supercapacitors are another important direction for future research.
