英文摘要 | Dual-ion batteries (DIBs) have attracted much attention due to their advantages of low cost and especially environmental friendliness. However, the capacities of most DIBs are still unsatisfied (≈100 mAh g−1) ascribed to the limited capacity of anions intercalation for conventional graphite cathode. In this study, 3D porous microcrystalline carbon (3D-PMC) was designed and synthesized via a self-templated growth approach, and when used as cathode for a DIB, it allows both intercalation and adsorption of anions. The microcrystalline carbon is beneficial to obtain capacity originated from anions intercalation, and the 3D porous structure with a certain surface area contributes to anions adsorption capacity. With the synergistic effect, this 3D-PMC is utilized as cathode and tin as anode for a sodium-based DIB, which has a high capacity of 168.0 mAh g−1 at 0.3 A g−1, among the best values of reported DIBs so far. This cell also exhibits long-term cycling stability with a capacity retention of ≈70% after 2000 cycles at a high current rate of 1 A g−1. It is believed that this work will provide a strategy to develop high-performance cathode materials for DIBs. |
