Transparent and stretchable Ag-Ni and Ag-Fe core-shell nanowire networks were fabricated as a cathode and anode, respectively, for asymmetric supercapacitors. Both electrodes showed a reversible stretchability at up to 100% strain and exhibited high electrochemical stability and specific capacitances of ∼3 mF cm with 50% optical transmittance. The asymmetric device assembled with a PVA/KOH electrolyte demonstrated a high operating voltage of 1.6 V and an excellent capacitance retention (92%) over 5000 cycles even after stretching to 35% strain.
分别制备了透明且可拉伸的Ag-Ni和Ag-Fe核壳纳米线网络,用作不对称超级电容器的阴极和阳极。两个电极在高达100%应变下均表现出可逆拉伸性,并具有高电化学稳定性和在50%透光率下约3 mF cm的比电容。用PVA/KOH电解质组装的不对称器件展示了1.6 V的高工作电压,即使在拉伸至35%应变后,在5000次循环中仍具有出色的电容保持率(92%)。
