[0022] Electrolyte configuration:
[0023] Electrolyte: Electrolyte 40ml, which contains 1.0moldm -3 MnSO 4 , 1 mold m -3 ZnSO 4 , 0.2moldm -3 h 2 SO 4 .
[0024] Battery Assembly:
[0025] Positive terminal plate, positive electrode 3x3cm in order of single cell 2 Nickel foam, negative electrode 3x3cm 2 Nickel foam, negative terminal plate. Single battery structure and system see figure 1 .
[0026] Battery test:
[0027] Electrolyte flow rate: 5ml / min; charge and discharge current density 10mA / cm 2 ; Charging for 1h, the discharge cut-off voltage is 0V. For battery performance see figure 2 , from the charge-discharge current density figure 2 It can be seen that at 10mA / cm 2 ; The charging time is 1h, and the average energy efficiency of the battery reaches about 70%.
