Abstract: Using waste disposable bamboo chopsticks as carbon source, bamboo-based porous carbon was prepared by direct pyrolysis followed by washing with deionized water after pretreatment with NaOH and Na₂SO₃. The surface morphology, specific surface area, pore structure and surface wettability were characterized and analyzed. The results showed that compared with bamboo-based porous carbon(PC-H) pretreated with deionized water, bamboo-based porous carbon(PC-Na) pretreated with NaOH and Na₂SO₃ mixture possessed high surface area(1 434 m²/g), well-developed porous structure(0.69 cm³/g) and excellent wettability(water contact angle of about 53.5°). Using the produced bamboo-based porous carbon as the positive electrode, the assembled aqueous Zn-ion hybrid supercapacitor(ZIHSC) displayed a high specific capacity of 75.6(mA·h)/g at a current density of 0.2 A/g. When the current density increased to 50 times, the specific capacitance retention rate was 52%, showing excellent rate performance. The maximum energy density was 59.3(W·h)/kg and the maximum power density was up to 7.6 kW/kg. The specific capacitance decays was only 2.7% after 5 000 charge-discharge cycles at a current density of 5 A/g, showing excellent cycle stability.
