摘要

Prussian blue analogues are commonly faced with the problem of poorer conductivity, fragile structural stability, and easy collapse of the frameworks during the cycling process, when directly used as electrode materials for lithium-ion batteries. Therefore, PBA-based hybrids with a multi-component structure have attracted widespread attention in lithium-ion batteries (LIBs), which could inherit the advantages and exhibit excellent synergistic effects of each component. More importantly, PBA@TMCs composites stand out among them, for the PBA framework providing the ordered pores and larger specific surface area for the transfer of lithium ions and electrons, and TMCs phase supplying high theoretical capacity, and N-doped carbon as the protective layer offering good conductivity and suppressing the volume expansion during the cycling process. In this study, a series of PBA@TMCs nanostructures have been successfully obtained and the proportion of the components in the complex is under control. In comparison with the single PBA and TMC phase as the anode in LIBs, the PBA@TMCs hybrids show enhanced cycling performance and rate capability, and the addition of MSs (metal sulfides) phase has the greatest contribution to the specific capacity in LIBs compared to MOs (metal oxides) and MPs (metal phosphides).
