Abstract

The present study investigates the impact of controlled shock waves on developing porous activated carbons (ACs) derived from low-cost Strychnos potatorum (Clearing-Nut) seeds for supercapacitor applications. ACs were synthesized using high-temperature carbonization (HTC) followed by physical activation. Uniquely, the process incorporated controlled dynamic shock waves on SPAC (ambient), SPAC 100, SPAC 200, and SPAC 300 to investigate their influence on the AC properties. Characterization techniques including physicochemical and electrochemical revealed that the application of shock waves significantly enhanced the ACs’ capacitance. Notably, SP-AC200 exhibited the best performance, achieving a specific capacitance of 290 F/g in a three-electrode system with 1 M H₂SO₄ electrolyte. Even in a two-electrode configuration, SPAC200 demonstrated an effective combination of high specific capacitance (118.3 F/g), energy density (23.1 Wh/Kg), and power density (583.09 W/kg). Additionally, SPAC200 displayed potential cyclic stability, retaining over 92.4 % of its capacitance after 10,000 cycles. This study highlights the potential of shock waves as a processing tool for fabricating high-performance supercapacitor electrodes from a sustainable and low-cost source.

声冲击驱动的马钱子马铃薯碳孔隙度调谐用于先进的超级电容器应用

本研究探讨了可控冲击波对制备多孔活性炭（ACs）的影响，这些活性炭是由低成本的马钱子马铃薯（清果）种子制备的，用于超级电容器。采用高温碳化-物理活化法制备了活性炭。独特的是，该工艺在SPAC（环境），SPAC 100， SPAC 200和SPAC 300上加入了受控的动态冲击波，以研究它们对交流性能的影响。物理化学和电化学表征技术表明，冲击波的应用显著提高了交流电的电容。值得注意的是，SP-AC200表现出最好的性能，在1 M H2SO4电解质的三电极系统中实现了290 F/g的比电容。即使在双电极配置下，SPAC200也显示出高比电容（118.3 F/g）、能量密度（23.1 Wh/Kg）和功率密度（583.09 W/ Kg）的有效组合。此外，SPAC200显示出潜在的循环稳定性，在10,000次循环后保持超过92.4%的电容。这项研究强调了冲击波作为一种加工工具的潜力，可以从可持续和低成本的来源制造高性能超级电容器电极。

期刊介绍： The Journal of Physics and Chemistry of Solids is a well-established international medium for publication of archival research in condensed matter and materials sciences. Areas of interest broadly include experimental and theoretical research on electronic, magnetic, spectroscopic and structural properties as well as the statistical mechanics and thermodynamics of materials. The focus is on gaining physical and chemical insight into the properties and potential applications of condensed matter systems. Within the broad scope of the journal, beyond regular contributions, the editors have identified submissions in the following areas of physics and chemistry of solids to be of special current interest to the journal: Low-dimensional systems Exotic states of quantum electron matter including topological phases Energy conversion and storage Interfaces, nanoparticles and catalysts.
