[0025] Further, a scale value 10 is provided on the container 11.

[0026] Specifically, three containers 11 are selected and respectively denoted as A, B, and C, and are inserted between the arc-shaped clamping plates 8 for fixation. Three batteries a, b, and c with different contents of zinc paste binder are selected. The contents of sodium polyacrylate in the zinc paste of a and b are d% and e% respectively. c is a battery with an unknown content of zinc paste binder;

[0027] The batteries a, b, and c are respectively dissected, and an equal mass of zinc paste m is taken out and placed in the containers A, B, and C respectively;

[0028] An equal volume of KOH solution with a content of 40% - 49% is respectively added into the containers A, B, and C. The ultrasonic generator 9 is started for ultrasonic treatment for 5 minutes and then left to stand. Then, the pump body 4 is started, the suction pipe 12 is removed and inserted into the container 11, and most of the separated solution is sucked out, leaving 1 ml of the solution covering the zinc powder. This is repeated twice;
