This Small Business Innovation Research (SBIR) Phase I project proposes the development of an innovative low-cost material synthesis route for the formation of porous carbons with finely controlled and uniform microstructure, tunable pore size, high surface area, and, most importantly, aligned micropores for rapid ion transport. Conventional supercapacitor electrodes are made of activated carbons with inconsistent properties and random tortuous pores that inhibit the flow of ions in the material. The proposed material will allow much higher power density and faster charge and discharge rates in supercapacitors, as needed by applications in smart electric grids, electric vehicles, energy-efficient industrial equipment and personal electronics.The broader/commercial impacts of this research are the dramatic enhancement in the performance with simultaneous reduction in cost of supercapacitors. Such improvements are expected to significantly increase the adoption of the supercapacitor technology by industry. The use of supercapacitors in transportation and industrial equipment leads to the dramatic reduction in energy consumption and greenhouse gas emission. Their applications in electrical grids enable the economic use of wind and ocean turbines. The elimination of the activation step in the porous carbon formation will avoid CO and CO2 emissions, thus improving the environmental friendliness of electrode manufacturing processes.

这个小企业创新研究（SBIR）一期项目提出了一种创新的低成本材料合成路线，用于形成多孔碳，具有精细控制和均匀的微观结构，可调节的孔径，高表面积，最重要的是，用于快速离子传输的排列微孔。传统的超级电容器电极是由性能不一致的活性炭和随机扭曲的孔隙制成的，这些孔隙会抑制材料中离子的流动。根据智能电网、电动汽车、节能工业设备和个人电子产品的应用需求，这种材料将使超级电容器具有更高的功率密度和更快的充放电速率。这项研究的更广泛/商业影响是超级电容器的性能显著提高，同时降低了成本。这些改进有望显著提高超级电容器技术在工业上的应用。超级电容器在交通运输和工业设备中的应用大大减少了能源消耗和温室气体排放。它们在电网中的应用使风力和海洋涡轮机的经济使用成为可能。消除多孔碳形成过程中的活化步骤将避免CO和CO2的排放，从而提高电极制造过程的环境友好性。
