Vanadium Flow Battery (VFB) 全钒液流储能电池 全钒液流电池是一种新型储能和高效转化装置，以不同价态的钒离子溶液作为电解液，通过电池 堆中电极的电化学反应，实现电能的储存和释放，这个可逆的反应过程使钒电池可顺利完成充电、 放电和再充电。 The VFB Energy Storage System (VFB-ESS) is an electrical energy storage system based on the vanadium-based redox regenerative fuel cell that converts chemical energy into electrical energy. Energy is stored chemically in different ionic forms of vanadium in a dilute sulphuric acid electrolyte. The reaction is reversible allowing the battery to be charged, discharged and recharged. 神 力 / r Shanghai Shen-Li High Tech Co., Ltd F e u w elCellPo Vanadium Flow Battery (VFB) 全钒液流储能电池 特点Characteristic： Long lifetime: Charge and discharge more than 100,000 times, 15 years. 系统使用寿命长，充放电次数超过100,000次，使用寿命达到15年以上。 High efficiency: Round-trip AC to AC efficiencies of system are 70-80%. 系统效率高，系统循环效率可达70-80%。 Support charge and discharge frequently, support charge and discharge under heavy current, can charge and discharge hundreds of times per day. 支持频繁充放电，支持频繁大电流充放电，每天可充放电数百次。 Support overcharge and over-discharge, DOD 80% 支持过充过放，支持深度充放电（DOD 80%）。 Rapidly charge and discharge, Charge-to-Discharge Duration Ratio : 1.6:1 充放电速度比为1.6:1，能够实现快速充放电。 Low self-discharge rate, and long-term storage. 自放电率低，可长期存放。 Fleetly response, response time＜1ms. 响应速度快，充放电切换时间小于1毫秒。 Customize system, power and capacity can be designed independently to meet different demands and system upgrade is easy. 电池系统定制化，功率与容量可独立设计。 Low maintenance cost, low operating cost. 维护成本低，运营成本低。 Environment friendly,
