Sodium-ion capacitors (SICs) are extremely promising due to the combined merits of high energy-power characteristics and considerable price advantage. However, it is still difficult to achieve high energy-power outputs and cycle stability in a typical configuration of the metal-based battery-type anode and activated carbon capacitor-type cathode due to the kinetic mismatching. In this work, a carbon nanosheet (PSCS-600) with large interlayer spacing of 0.41 nm derived from the bio-waste pine cone shell was prepared. Besides, the covalent triazine framework derived carbon (OPDN-CTF-A) was obtained through ionothermal synthesis strategy, exhibiting beneficial hierarchical pores (0.5–6 nm) and high heteroatoms (5.6 at% N, 6.6 at% O). On this basis, the all-carbon SICs were fabricated by the integration of PSCS-600 anode and OPDN-CTF-A cathode. The device delivered high energy density 111 Wh kg⁻¹, high power output of 14,200 W kg⁻¹ and ultra-stable cycling life (~90.7% capacitance retention after 10,000 cycles). This work provides new ideas in fabricating carbon–carbon architectural SICs with high energy storage for practical application.

钠离子电容器（SIC）由于具有高能量-功率特性和可观的价格优势的综合优点而非常有前途。然而，由于动力学失配，在金属基电池型阳极和活性炭电容器型阴极的典型构造中，仍然难以实现高能量-功率输出和循环稳定性。在这项工作中，从生物废料的松果壳中提取的碳纳米片（PSCS-600）的层间间距为0.41 nm。此外，通过电热合成策略获得了由三嗪骨架衍生的共价碳（OPDN-CTF-A），具有有益的分层孔（0.5–6 nm）和高杂原子（5.6 at％N，6.6 at％O）。在此基础上，通过整合PSCS-600阳极和OPDN-CTF-A阴极来制造全碳SIC。^-1，14200公斤w ^的高功率输出^-1和超稳定循环寿命（〜90.7％容量保持后10,000次循环）。这项工作为制造具有高能量存储的碳-碳建筑SIC提供了新的思路，供实际应用。
