摘要: Electrical contact outlet for an anode sheet of a lithium generator with polymer electrolyte, consisting of one or more multilayer electrochemical cells. The cell comprises at least one lithium base sheet having a thickness between about 1 and 50 microns to constitute the anode and its collector and additionally includes a cathode and its collector as well as the polymer electrolyte. A lateral end of the anode sheet extends beyond corresponding ends of the cathode and the collector to constitute a projecting zone. A metallic layer consisting of at least one rigid metal which is compatible with lithium is in electrical contact with the lateral end of the anode sheet but without electronic contact with the other components of the cell. The metallic layer constitutes the external terminal of the generator when the latter is in non-finished condition. According to a variant, a conductive and cohesive intermediate metallic zone, which consists of lithium or lithium rich ductile alloys is in intimate contact with the lateral end of the anode sheet and the metallic layer mentioned above is therefore in electrical contact with the lateral end of the anode sheet by means of the intermediate zone of lithium. Generators provided with such contact outlet as well as a process for the preparation of these contact outlets are described.

摘要: A battery controller for charging and discharging a plurality of batteries is disclosed. The battery controller has a plurality of direct current to direct current (DC to DC) converters connected to each other in series. Each battery of a plurality of batteries is electrically connectable to a respective DC to DC converter. A co-ordinator connected to each of the plurality of DC to DC converters controls charging and discharging of the battery electrically connected to the respective converter. The co-ordinator can also control charging and discharging of any one of the batteries to ensure that the battery retains sufficient electrical capacity, and, to increase the longevity of the respective batteries. Because each battery is electrically connected to a respective DC to DC converter, the energy from one battery can be used to charge another battery in order to monitor battery characteristics including energy capacity of each battery. Each of the DC to DC converters is selected to operate preferably below 30 volts while the total voltage of the entire battery system can be much more than 30 volts depending on the number of DC to DC converters placed in series.

摘要: A matted particulate electrode located between the current collector and a porous separator of a rechargeable lithium battery is described, which contains electro-active particles intermixed with pliable, solid, lithium ion conducting, polymer electrolyte filaments having adhesive surfaces. The electro-active particles and the optionally added electro-conductive carbon particles adhere to the tacky surface of the adhesively interlinking polymer electrolyte filaments. The matted particulate electrode is impregnated with an organic solution containing another lithium compound. In a second embodiment the porous separator is coated on at least one of its faces, with polymer electrolyte having an adhesive surface and made of the same polymer as the electrolyte filaments. The polymer electrolyte filaments in the matted layer may adhere to the coated surface of the separator. In addition the polymer coating is partially filling the pores of the porous electrolyte, but leaving sufficient space in the pores for the organic solution to penetrate the separator of the lithium battery.

摘要: The terminals of a thin plate rechargeable lithium battery are coated with a heat-sealable polymer. The coating forms a band on each face of the terminals and the band is heat-sealed to the inner insulator layers of a multi-layered polymer laminate enclosing the thin plate rechargeable lithium battery at a location close to an open edge of the insulator layer. Small sheets of rigid, high melting point, polymeric materials are inserted between the bands of coating carried by the terminals and the edge of the multi-layered laminate enclosing the lithium battery. A portion of the sheets of polymeric material is adhesively attached to the face of the terminal adjacent the bands of coating. The open edges of the multi-layered polymer laminate enclosure are subsequently sealed to enclose completely the thin plate lithium battery.
