Supercapacitors, as a type of energy storage system, bridge the power/energy gap between conventional capacitors and batteries due to attractive properties such as high power density, long cycle lifespan, and large temperature range. However, the low energy density of supercapacitors compared to lithium‐ion batteries has hindered their general application. In general, the electrochemical performance of supercapacitors is closely related to the structure of their electrode materials, electrolytes, and device design. The main materials used in electrochemical double‐layer capacitors (EDLCs) are carbon materials with various architectures. This is due to their high surface area, good electric conductivity, and intrinsic stability. In this review, recently reported carbon‐based nanostructured electrode materials with 0D, 1D, 2D, and 3D structures are systematically reviewed. The effect of nanostructuring on the properties of supercapacitors including specific capacitance, rate capability, and cycle stability is explored, the details of which may serve as a guide to electrode design for the next generation of EDLCs.

“…Some biomass rich in organic salts such as citrates including K, Na, Ca, and so on, can also self‐activate to produce satisfactory porous structure, which not only further reduces the production cost, simplifies the preparation steps, but also is environmental friendly, providing new ideas for biomass selection. Figure shows a possible mechanism of self‐activation process of biomass, in which inorganic salts acted as templating agents, forming hierarchical porous structure . For example, nanostructured carbon was prepared using seaweed without any further activation, exhibiting the specific capacitance of 264 F/g as SCs electrodes on account of the moderate SSA and a rich oxygenated surface functionality .…”

Summary Biomass is one of the most promising clean energy sources. The porous carbon materials prepared by biomass as electrode materials of electric double‐layer capacitors (EDLCs) are easily available at a low price, which would greatly reduce the cost of the production. However, carbon materials made with biomass generally have many disadvantages such as low specific surface area (SSA), poor pore size structure, and difficulty to control the pore diameter, which results in the poor EDLC performance. In this paper, the prime purpose is to expose the recent progress of biomass carbon in the fields of electrode materials of EDLC. The review provides a comprehensive literature review that is focused on EDLC electrodes derived from biochar of the evidence of 181 publications published over a period of 30 years from 1989 to 2019. Various carbon materials derived from different biomass for electrode of EDLC are discussed. The most promising methods for the preparation of several biomass carbons are described in detail. Some factors such as SSA, pore size structure, surface functional groups, and electrolyte are further analyzed to discuss the effects on the electrochemical performance of the EDLC. Notably, current deficiencies and possible solutions of preparation methods of biomass carbon as electrode materials are outlined. And the future research trends in this field are prospected.
