CA 2314626
A secondary electrochemical cell with at least one positive electrode and at least one negative electrode, said electrodes each comprising an active material are being directly received by a hermetically tight housing which includes or is in operative connection with at least one detector element. The detector element is designed or can be set to sense a predetermined unallowable operating state of the secondary electrochemical cell, and in an unallowable operating state of the secondary electrochemical cell, to actuate at least one switching element which prevents recharging and/or discharging of the secondary electrochemical cell. By making the housing as a hermetically tight protective housing, which is part of an implantable medical device, contamination of surrounding tissue with toxic substances and hazard to the implant wearer by a malfunction of the secondary electrochemical cell can be precluded under all operating conditions. Simultaneously all dimensions involved may be greatly reduced.
