Hermetically sealed electric battery comprising hermetically sealed electrochemical control cell
Abstract
Abstract A ELECTROCHEMICAL CONTROL DEVICE FOR USE PARTICULARLY IN CONNECTION WITH STORAGE BATTERIES IS FORMED OF AT LEAST ONE HERMETICALLY SEALED CELL IN WHICH POSITIVE AND NEGATIVE ELECTRODES ARE ARRANGED INCLUDING IDENTICAL ACTIVE MASS SO THAT THE ELECTRODES ARE OF POTENTIALLY CHANGEABLE OPPOSITE POLARITY, WHEREBY AT THE TIME OF STARTING OPERATION, THE AMOUNT OF REDUCEABLE MATERIAL IN THE ACTIVE MASS OF THE ELECTRODE SERVING AS CATHODE, MEASURED IN ELECTRTOCHEMICAL EQUIVALENTS, IS GREATER THAN THE AMOUNT OF OXIDIZABLE MATERIAL IN THE ACTIVE MASS OF THE ELECTRODE SERVING AS ANODE, AND WHEREIN UP TO 40% OF THE COMBINED AMOUNT OF THE ACTIVE MASSES OF THE CATHODE AND THE ANODE, MEASURED IN ELECTROCHEMICAL EQUIVALENTS, IS IN REDUCED CONDITION.
