Abstract

Current trends suggest that as manufacturing and energy demand increase, there will be a greater consumtion for energy storage, requiring its utilization for days, weeks, or even months in the future. Recent studies also need to be conducted on binders that could support electrode performance, considering that binders are also a crucial component of the electrochemical processes in cells. In this study, activated carbon-based supercapacitor electrodes were fabricated using three different binders: PVDF, SBR, and LA133. With a gravimetric capacitance and power density of 52.57 Fg⁻¹ and 92.64 W.kg⁻¹, and a lifetime up to 87.23% after 1000 cycles, AC/CB LA133 has the best performance. LA133 was used as a binder to generate a Ni/Si composite as a battery electrode combined with the AC/CB LA133 supercapacitor to fabricate a supercapattery. This clearly shows that when a suitable binder such as LA133 is used, the electrochemical performance could be improved.

活性炭-镍硅复合材料超级电容器电极粘结剂聚合物的综合研究

目前的趋势表明，随着制造业和能源需求的增加，能源存储将会有更大的消耗，未来需要使用几天、几周甚至几个月。考虑到粘合剂也是电池中电化学过程的关键组成部分，最近的研究还需要对支持电极性能的粘合剂进行研究。在这项研究中，活性炭基超级电容器电极由三种不同的粘合剂:PVDF, SBR和LA133制成。AC/CB LA133的重量电容和功率密度分别为52.57 Fg−1和92.64 W.kg−1,1000次循环后的寿命高达87.23%，性能最佳。以LA133为粘结剂制备Ni/Si复合材料作为电池电极，与AC/CB LA133超级电容器结合制备超级电容器。这清楚地表明，当使用合适的粘结剂(如LA133)时，可以提高电化学性能。
