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 can be recharged by the energy storage battery. In this way, the power battery temporarily stores electrical energy received from the energy battery and both batteries can provide 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: 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.
