Patent number: 11289702Abstract: An electrochemical voltage source has an anode containing lithium, a cathode containing manganese oxide, and a housing. The cathode and the anode are arranged in an interior of the housing and are arranged opposite one another. An electrolyte reservoir in the form of a compressible storage body, which receives an electrolyte, is arranged between the anode and the cathode. The storage body has a first side resting against an end face of the cathode and a second side, which faces away from the first side, and rests against an end face of the anode. The cathode experiences an increase in volume when the voltage source is discharged. The anode experiences a decrease in volume during the discharge. During the discharge, the absolute value of the volume increase of the cathode is at least as great as the absolute value of the volume decrease of the anode.Type: GrantFiled: August 13, 2018Date of Patent: March 29, 2022Assignee: LITRONIK Batterietechnologie GmbHInventors: Nico Freyer, Michael Roch, Roland Staub, Tim Traulsen, Gerd Fehrmann

Patent number: 6044295Abstract: An implantable multi-function medical device, having a first therapy assembly that has a small current requirement and a second therapy assembly that has a large current requirement. The device further has a first battery component that is adapted to a consumer having a low current requirement, and a second battery component that is adapted to a consumer having a large current requirement, and a switching device which connects the second battery component only to the second therapy assembly until a control signal is emitted, which indicates that a predetermined voltage level of the first battery component has not been met, or that an internal resistance has been exceeded, but, as of this time, the switching device connects the second battery component to the first therapy assembly.Type: GrantFiled: April 16, 1998Date of Patent: March 28, 2000Assignee: Litronik Batterietechnologie GmbH & Co.Inventors: Juergen Pilz, Juergen Mueller, Roland Staub, Gerd Fehrmann

Patent number: 5713936Abstract: A battery-operated implantable medical device comprises a battery, a measuring device for determining the state of charge of the battery through measurement of the no-load voltage, and an electric load. The no-load voltage of the battery has an increased drop in a range in which a remaining residual energy suffices to keep the operation of the device going for a minimum period of time required to carry out a therapeutic process.Type: GrantFiled: January 23, 1996Date of Patent: February 3, 1998Assignee: Litronik Batterietechnologie GmbH & Co.Inventors: Roland Staub, Gerd Fehrmann, Rudiger Wolf, Thomas Fischer, Hartmut Heimer

Patent number: 5587258Abstract: A sealed galvanic cell which has high power and energy densities, a low self discharge, and an open circuit voltage which is related to state of discharge, and which is useful for supplying electrical power to an implantable device, such as a defibrillator and a nerve stimulator, with a large current consumption, and method of making same. The galvanic cell includes a casing; a cathode unit having at least one electrode composed of a mixture of at least one metal oxide and at least one lead compound; an anode unit having at least one electrode comprised of an alkali metal; and an organic electrolyte comprised of a mixture of (a) ethylene- and/or propylene carbonate, (b), 2-dimethoxyethane, and (c) a conducting salt. The mixture of the cathode unit is one of (a) a mixture of CrO.sub.x (x=2.5 to 2.7) and at least one lead compound from among PbCrO.sub.4, PbMoO.sub.4 and PbO, (b) a mixture of CrO.sub.x (x=2.5 to 2.7), MnO.sub.2, and at least one lead compound from among PbCrO.sub.4, PbMoO.sub.Type: GrantFiled: January 5, 1996Date of Patent: December 24, 1996Assignee: Litronik Batterietechnologie GmbH & Co.Inventors: Gerd Fehrmann, Rainer Frommel, Rudiger Wolf
