Title: Self-discharge preventing method for electrolyte low type cell
Inventor: AO NORIO
IPC: H01M8/04
Filed: 1987-12-14
Abstract: PURPOSE:To prevent self-discharge in a cell operation suspension period by adopting a serial electrolyte supply method as an electrolyte flowing means, and filling only an uncharged electrolyte, or discharged electrolyte, in electrolytic baths. CONSTITUTION:Before the operation of an electrolyte flow type cell is suspended, uncharged electrolyte is filled in electrolytic baths of the electrolyte flow type cell by supplying uncharged electrolyte from the first electrolyte tank 1 in which the uncharged electrolyte is stored to the second electrolyte tank 1a in which charged electrolyte is stored, then the electrolyte flow type cell is kept in an operation suspension state. Since a serial electrolyte-supply method differs from a parallel electrolyte-supply method, uncharged electrolyte (discharged electrolyte) always exists in the tank when the cell is stopped and suspended, an electrolyte in the electrolytic baths is replaced with uncharged electrolyte. Since this electrolyte is almost completely discharged, the flow of leak current is very small. Self-discharge in a cell operation period is prevented.
