随着便携式电子设备、电动汽车以及大规模电网储能设备的快速发展，需要提高相关电化学装置的比能量密度和比功率密度，以满足快速增长的储能需求。电池 - 超级电容器混合装置（BSHDs）结合了电池的高能量密度特性和超级电容器的高功率密度特性，在储能方面引起了广泛关注。然而，BSHDs的阴极材料的电化学性能受到导电性差和离子传输动力学不佳的严重限制。由于过渡金属化合物引发的丰富氧化还原反应能够提供高比容量，它们是阴极材料的理想选择。因此，本文综述了BSHDs中具有高倍率性能的基于过渡金属化合物的阴极的当前先进进展。我们讨论了一些提高过渡金属化合物倍率性能的有效策略，包括开发具有高导电性和快速离子传输的本征电极材料；对材料进行改性，如插入缺陷和掺杂；构建复合结构和3D纳米阵列结构；界面工程和催化效应。最后，对BSHDs阴极的潜在发展提出了一些建议，这可能为未来的重大进展提供参考。

With the rapid development of portable electronic devices, electric vehicles and large-scale grid energy storage devices, there is a need to enhance the specific energy density and specific power density of related electrochemical devices to meet the fast-growing requirements of energy storage. Battery-supercapacitor hybrid devices (BSHDs), combining the high-energy-density feature of batteries and the high-power-density properties of supercapacitors, have attracted mass attention in terms of energy storage. However, the electrochemical performances of cathode materials for BSHDs are severely limited by poor electrical conductivity and ion transport kinetics. As the rich redox reactions induced by transition metal compounds are able to offer high specific capacity, they are an ideal choice of cathode materials. Therefore, this paper reviews the currently advanced progress of transition metal compound-based cathodes with high-rate performance in BSHDs. We discuss some efficient strategies of enhancing the rate performance of transition metal compounds, including developing intrinsic electrode materials with high conductivity and fast ion transport; modifying materials, such as inserting defects and doping; building composite structures and 3D nano-array structures; interfacial engineering and catalytic effects. Finally, some suggestions are proposed for the potential development of cathodes for BSHDs, which may provide a reference for significant progress in the future. With the rapid development of portable electronic devices and large-scale grid energy storage devices, it is need to enhance the specific energy and power density of electrochemical devices to meet the fast-growing requirements of energy storage.
