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 (approximate to 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 approximate to 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.
