Silver nanowires (Ag NWs) have attracted particular interest in the development of various electronic and energy storage devices due to their one-dimensional structure, good conductivity, fast charge transportation and direct contact to the current collector. Herein, we have successfully deposited the binder-free nickel-cobalt layered double hydroxide nanosheets on Ag NWs-fenced carbon cloth (NC LDH NSs@Ag@CC) by a facile electrochemical deposition method with a chronoamperometry voltage of −1.0V for 120s. The electrically conductive and superhydrophilic nature of the hybrid nanocomposite electrode exhibited higher areal capacitance (1133.3 mF cm⁻² at 1mAcm⁻²) and a good cycling stability (80.47% after 2000 cycles) compared to the electrode prepared without Ag NWs. Using such hierarchical NC LDH NSs@Ag@CC as a positive electrode, we further fabricated a flexible asymmetric supercapacitor (ASC) with activated carbon coated CC as a negative electrode. The as-assembled ASC demonstrate possess maximum operation potential window of 1.6V, high areal capacitance 230.2 mF cm⁻², the excellent cycling stability of 88.1% with a remarkable energy densities at all charge-discharge conditions (78 μWh cm⁻² at the power density of 785 μW cm⁻² and 40 μWh cm⁻² at the high power density of 12.1mWcm⁻², respectively)

导电银纳米线刺穿碳布纤维支撑的层状双氢氧化物纳米片，作为柔性和无粘合剂的电极，用于高性能不对称超级电容器

银纳米线（Ag NWs）由于其一维结构，良好的导电性，快速的电荷传输以及与集电器的直接接触，在各种电子和能量存储设备的开发中引起了特别的兴趣。在这里，我们已经成功地通过一种简便的电化学沉积方法，用计时电流法电压为-1.0V的120s在Ag NWs固定的碳布（NC LDH NSs @ Ag @ CC）上沉积了无粘合剂的镍钴层状双氢氧化物纳米片。混合纳米复合电极的导电性和超亲水性质表现出较高的单位面积电容（1133.3 mF及其厘米^-2在1mAcm ^-2）和不使用Ag NW制备的电极相比，具有良好的循环稳定性（2000次循环后为80.47％）。使用这种分层的NC LDH NSs @ Ag @ CC作为正极，我们进一步制造了柔性非对称超级电容器（ASC），其中活性炭包覆的CC作为负极。组装后的ASC证明具有1.6V的最大工作电势窗口，230.2 mF cm ^-2的高面电容，88.1％的出色循环稳定性以及在所有充放电条件下（78μWhcm ^-2时的能量密度都非常高）。 785μW厘米的功率密度^-2和40μWh厘米^-2在12.1mWcm的高功率密度^-2，分别地）
