摘要

The everyday use of disposable bamboo-based products has prompted us to recycle their waste into carbon materials for adsorbents [1,2] and electrodes for electric double layer capacitors (EDLCs). Hitherto diverse carbon precursors including abundant biomass materials have been investigated to prepare activated carbons (ACs) as electrode materials with high surface area, large porosity and homogeneous pore size [3-5]. In general, the pore structure and size of ACs strongly depend on the types of their precursor and activation process [6]. In this work, the activation of bamboo-based carbons was examined at various ratios of KOH. Furthermore, the specific capacitance of the bamboo-based AC electrodes was evaluated using two different kinds of (aqueous and non-aqueous) electrolytes with different ion sizes, whereby detailed information about the structure and size of the developed pores has been obtained.
