Flexible energy storage electrodes with high conductivity and capacity are crucial for wearable electronic clothes. Herein, a flexible hierarchical Ni(OH)₂/Cu(OH)₂ interwoven nanosheets in situ coated on Ni–Cu–P alloy plated cotton fabric textile (NCO/CF), which displays perfect conductive and electrochemical performance, is prepared by electroless deposition and electrochemical oxidation method. While the Ni–Cu–P alloy layer coated on the fabric effectively contributes to excellent mechanical performance and electro-conductivity of the as-prepared NCO/CF electrode, the hierarchical Ni(OH)₂/Cu(OH)₂ interwoven nanosheets in the oxidation layer effectively lead to a high energy storage performance with a specific areal capacity of 4.7 C cm⁻² at a current density of 2 mA cm⁻². When the power density of the two-electrode system based on NCO/CF and the carbon cloth (CC) is 2.4 mW cm⁻², the energy density is 1.38 mW h cm⁻². Furthermore, the flexible solid-state energy storage f-NCO/CF//CC is assembled in a self-powered system and supplies continuous power for electronic devices, demonstrating that NCO/CF is promising to be applied in various energy storage devices to power portable and wearable devices in the future.

在 Ni-Cu-P 合金镀棉织物上原位生长的分级 Ni(OH)2/Cu(OH)2 交织纳米片用于柔性高性能储能

具有高导电性和容量的柔性储能电极对于可穿戴电子服装至关重要。在此，通过化学镀制备了一种柔性多级 Ni(OH) ₂ /Cu(OH) ₂交织纳米片原位涂覆在 Ni-Cu-P 合金镀棉织物 (NCO/CF) 上，具有良好的导电和电化学性能。沉积法和电化学氧化法。虽然涂覆在织物上的 Ni-Cu-P 合金层有效地有助于所制备的 NCO/CF 电极的优异机械性能和导电性，但分层的 Ni(OH) ₂ /Cu(OH) ₂氧化层中交织的纳米片有效地导致高能量存储性能，在2 mA cm ^-2的电流密度下具有4.7 C cm ^-2的比面积容量。当基于NCO/CF和碳布(CC)的双电极系统的功率密度为2.4 mW cm ^-2时，能量密度为1.38 mW h cm ^-2。此外，柔性固态储能f-NCO/CF//CC被组装在一个自供电系统中，为电子设备提供持续的电力，表明NCO/CF有望应用于各种储能设备来为电子设备供电。未来的便携式和可穿戴设备。
