    Abstract: 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.

    Abstract: An electrical energy storage device for storing electrical energy and supplying the electrical energy to a driving motor at different power levels is disclosed. The electrical storage device has an energy battery connected to a power battery. The energy battery has a higher energy density than the power battery. However, the power battery can provide electrical power to the electrical motor at different power rates, thereby ensuring that the motor has sufficient power and current when needed. The power battery is continuously recharged by the energy storage battery. In this way, the power battery temporarily stores electrical energy received from the energy battery and provides the electrical energy at the different power rates as required by the motor. The energy storage device can be releasably connected to an external power source in order to recharge both batteries. Both batteries can be recharged independently to optimize the recharging and lifetime characteristics of the batteries.

    Abstract: 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.
