双离子电池（DIBs）通常使用碳基材料作为电极，具有工作电压高、潜在成本低、环境友好等优点。与二次电池传统的“摇椅式”工作机制不同，DIBs具有独特的工作机制，在电化学反应过程中，阳离子和阴离子分别在负极和正极参与容量贡献。在高工作电压下（>4.8 V），阴离子嵌入石墨正极具有优异的反应动力学。然而，Li+在负极侧往往扩散速率较为缓慢，导致正极和负极之间的动力学失配，严重制约了DIBs的发展。本文通过微观结构调控策略制备了毛竹衍生碳（PEC），该策略有效地调控了PEC丰富的短程有序石墨微畴和无序非晶区，并具有独特的分级纳米孔结构。其纳米孔的孔径分布主要集中在0.5-5 nm，为Li⁺提供了合适的快速传输通道，在300 mA·g^-1电流密度下达到了436 mAh·g^-1的高可逆容量和优异的倍率性能（在3 A·g^-1时保持了231 mAh·g^-1的高容量）。组装的双碳PEC-500||石墨全电池在10 C倍率下具有114 mAh·g^-1的容量，循环3000圈后具有96%的容量保持率，同时，全电池在50 C倍率测试中仍能够保持74 mAh·g^-1的容量，表现出优异的倍率性能。

Dual-ion batteries (DIBs), which usually using carbon-based materials as electrodes, showing advantages in high operating voltage, potential low cost, and environmental friendliness. Different from conventional “rocking chair” of secondary batteries, DIBs performed a unique working mechanism, which employ both cation and anion take part in capacity contribution at anode and cathode, respectively, during electrochemical reactions. Graphite has been identified a suitable cathode material for anion intercalation at high voltage (>4.8 V) with fast reaction kinetics. However, the development of DIBs is being hindered by dynamic mismatch between cathode and anode due to sluggish Li⁺ diffusion at high rate. Herein, we prepared phyllostachys edulis derived carbon (PEC) through micro structure regulation strategy, which effectively tailored the rich short-range ordered graphite microdomains and disordered amorphous regions, as well as a unique nano-pore hierarchical structure. The pore size distribution of nano-pores is concentrated in 0.5-5 nm, providing suitable channels for rapid Li+ transportation, achieving a high capacity of 436 mAh·g^-1 at 300 mA·g^-1 and excellent rate performance (maintaining a high capacity of 231 mAh·g^-1 at 3 A·g^-1). The assembled dual-carbon PEC-500||graphite full battery delivered 114 mAh·g^-1 at 10 C with 96% capacity retention after 3000 cycles and outstanding rate capability, providing 74 mAh·g^-1 at 50 C.
