Abstract

Materials made of amorphous carbon that includes nitrogen have been extensively researched for use as negative electrodes in systems that store energy like lithium-ion batteries (LIBs). Graphene platelets (GP) covered with polyaniline (PANi) were effectively created through polymerization and utilized as anode material for lithium-ion batteries. The prepared AGP composite material, utilized in lithium-ion batteries as an anode material (AM), was evaluated for its electrochemical properties. It produced a specific capacity (SC) of 450 mAhg⁻¹ for 160 electrochemical cycles at a current density (CD) of 100 mAg⁻¹ and 256 mAhg⁻¹ for 500 cycles at a high current density (CD) of 1 Ag⁻¹. These suggest that it could be a good option for the anode material (AM) in lithium-ion batteries (LIBs).

作为锂离子电池负极的聚苯胺衍生无定形碳共形涂层多层石墨烯平板

由含氮无定形碳制成的材料已被广泛研究用于锂离子电池（LIB）等储能系统的负极。通过聚合作用有效地制造出了覆盖聚苯胺（PANi）的石墨烯平板（GP），并将其用作锂离子电池的负极材料。所制备的 AGP 复合材料在锂离子电池中用作负极材料 (AM)，对其电化学性能进行了评估。在电流密度（CD）为 100 mAg-1 的条件下，160 次电化学循环的比容量（SC）为 450 mAhg-1；在电流密度（CD）为 1 Ag-1 的条件下，500 次电化学循环的比容量（SC）为 256 mAhg-1。这表明它可以成为锂离子电池（LIB）中阳极材料（AM）的良好选择。

期刊介绍： DRM is a leading international journal that publishes new fundamental and applied research on all forms of diamond, the integration of diamond with other advanced materials and development of technologies exploiting diamond. The synthesis, characterization and processing of single crystal diamond, polycrystalline films, nanodiamond powders and heterostructures with other advanced materials are encouraged topics for technical and review articles. In addition to diamond, the journal publishes manuscripts on the synthesis, characterization and application of other related materials including diamond-like carbons, carbon nanotubes, graphene, and boron and carbon nitrides. Articles are sought on the chemical functionalization of diamond and related materials as well as their use in electrochemistry, energy storage and conversion, chemical and biological sensing, imaging, thermal management, photonic and quantum applications, electron emission and electronic devices. The International Conference on Diamond and Carbon Materials has evolved into the largest and most well attended forum in the field of diamond, providing a forum to showcase the latest results in the science and technology of diamond and other carbon materials such as carbon nanotubes, graphene, and diamond-like carbon. Run annually in association with Diamond and Related Materials the conference provides junior and established researchers the opportunity to exchange the latest results ranging from fundamental physical and chemical concepts to applied research focusing on the next generation carbon-based devices.
