Special Issue Information

Dear Colleagues,

To satisfy increasing energy demands in a low-carbon economy, the development of new materials that improve the efficiency of energy conversion and storage systems is critical to future energy transition. Carbonaceous materials provide tremendous opportunities in energy conversion and storage applications owing to their exceptional electrical conductivity, outstanding physicochemical stability, and tunable surface architectures. Over the past three decades or so, considerable efforts have been made to exploit the unique properties of carbon nanomaterials such as fullerenes, carbon nanotubes, and graphene to use them as energy materials, with tremendous progress in the development of high-performance energy conversion (e.g., solar cells and fuel cells) and storage (e.g., supercapacitors and batteries) devices, from their synthesis to their practical applications. This Special Issue aims to gather articles that provide an overview of the most recent advancements in various carbon materials toward energy conversion and storage in diverse areas, including but not limited to solar and fuel cells, batteries, and electrocatalytic applications.

The conversion of low-cost, widely available, and renewable agricultural and forestry biomass waste into high-performance electrode materials for supercapacitors has attracted significant research interest. In this study, bamboo was used as a raw material to prepare bamboo-derived activated carbon (BAC) and nitrogen-doped biomass activated carbon (N-BAC) via a two-step process involving carbonization and KOH activation. The obtained materials were subsequently evaluated as electrode materials for supercapacitors. The effects of carbonization temperature and time, activation temperature and time, and impregnation ratio on the structural properties and iodine adsorption capacity of the activated carbons were systematically examined. The results revealed that all process parameters influenced the iodine adsorption value of the samples in a volcano-type trend. The BAC prepared under optimized conditions (carbonization at 600 °C for 60 min, activation at 850 °C for 60 min, and an impregnation ratio of 6:1) exhibited the highest specific surface area (3013.30 m2/g), a total pore volume of 1.5813 cm3/g, and an average pore diameter of 2.0992 nm. Although nitrogen doping slightly reduced the specific surface area and pore volume of BAC, the introduced nitrogen-containing functional groups participated in redox reactions with the electrolyte, leading to a significant enhancement in the electrochemical performance of N-BAC. In a 6.0 M KOH electrolyte at a scan rate of 0.01 V/s, the specific capacitance of N-BAC reached 288.8 F/g, exceeding that of the optimized BAC (180.85 F/g). The supercapacitor assembled with N-BAC demonstrated a high energy density of 14.4 Wh/kg at a power density of 73.1 W/kg in aqueous electrolyte, the specific capacitance retention rate is about 90.3% after 5000 cycles between −1.2 V and 0 V at a scan rate of 10 mV/s. Overall, this work successfully developed high-performance supercapacitor electrode materials, providing a promising approach for the high-value utilization of biomass resources. Full article
