Abstract

In this study, CuO nanorods and CuO/graphene aerogel (GA) composites are investigated as potential anode materials. CuO nanorods were synthesized by chemical precipitation, while the CuO/graphene aerogel hybrid was prepared by the aerogel method. Structural, morphological and electrochemical characterizations were performed, which showed enhanced performance of the CuO/GA hybrid composite. This composite structure retained 90 % of its capacitance after 500 cycles, significantly outperforming the pure CuO electrode. The unique properties of CuO's high theoretical capacity combined with graphene's superior conductivity lead to enhanced lithium storage and structural resilience. This study examines CuO nanorods combined with graphene aerogels to leverage graphene exceptional conductivity and 3D porous structure for improved performance.

使用氧化铜纳米棒/石墨烯气凝胶复合材料提高锂离子电池阳极的性能

在本研究中，研究了CuO纳米棒和CuO/石墨烯气凝胶（GA）复合材料作为潜在的阳极材料。采用化学沉淀法合成了CuO纳米棒，采用气凝胶法制备了CuO/石墨烯气凝胶杂化物。通过结构、形貌和电化学表征，表明该复合材料的性能得到了增强。这种复合结构在500次循环后保持了90%的电容，明显优于纯CuO电极。CuO的高理论容量与石墨烯优异的导电性相结合，可以增强锂的存储能力和结构弹性。本研究考察了CuO纳米棒与石墨烯气凝胶的结合，以利用石墨烯卓越的导电性和3D多孔结构来提高性能。

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.
