摘　　要：用低温等离子体改性碳布构建了具有长寿命的水系锌离子电池三维结构负极。负极表面疏松多孔的沉积层有利于电解液的渗入提高锌的利用率,且能够在充放电过程中容纳锌从而实现抑制锌枝晶延长电池使用寿命的目的。使用该负极组装的对称电池的寿命从360 h提高到480 h,与活性炭正极组装的全电池在1 A·g^(-1)的电流密度下循环800圈后的容量保持率为70%,远高于未经处理的20%。A three-dimensional anode with long service life for water based zinc ion battery was constructed by modifying carbon cloth with low-temperature plasma.The loose and porous deposit layer on the negative electrode surface is conducive to the penetration of electrolyte to improve the utilization rate of zinc,and can contain zinc in the charge discharge process to achieve the purpose of inhibiting zinc dendrites and extending the service life of the battery.The service life of the symmetrical battery assembled with the negative electrode is increased from 360 h to 480 h.The capacity retention rate of the whole battery assembled with the positive electrode of activated carbon after 800 cycles at a current density of 1 A·g^(-1) is 70%,which is much higher than that of the untreated battery by 20%.
