This study presents the research progress in carbon-assisted conversion reaction-based metal oxides for high-performance anodes of lithium-ion batteries (LIBs). Conversion reaction-based metal oxides as anodes for LIBs suffer from large volume variations during charging/discharging processes, which would result in poor conductivity and fading capacity. In the past decade, various conversion reaction-based metal oxides have been integrated into different carbon nanostructures including one-dimensional nanostructures (carbon nanotubes, carbon nanofibers), two-dimensional nanostructures (graphene, graphene oxides), three-dimensional nanostructures (carbon networks, carbon foam) as well as porous carbon materials. This study describes the structures and properties of these composites and further focuses on the synergistic effects of hybrid nanostructures on the specific capacitance, rate capacity and cyclability. This study also briefly discusses charge transport, ion diffusion, and the related reaction energy barriers.

碳辅助转化反应型锂离子电池氧化物纳米材料

这项研究提出了用于锂离子电池（LIBs）高性能阳极的基于碳辅助转化反应的金属氧化物的研究进展。用作LIB阳极的基于转化反应的金属氧化物在充电/放电过程中会发生较大的体积变化，这将导致较差的电导率和褪色能力。在过去的十年中，各种基于转化反应的金属氧化物已被整合到不同的碳纳米结构中，包括一维纳米结构（碳纳米管，碳纳米纤维），二维纳米结构（石墨烯，氧化石墨烯），三维纳米结构（碳网络）。，碳泡沫）以及多孔碳材料。这项研究描述了这些复合材料的结构和性能，并进一步关注了杂化纳米结构对比电容，倍率容量和可循环性的协同作用。这项研究还简要讨论了电荷传输，离子扩散和相关的反应能垒。
