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: The composite electrolyte for use in a thin plate rechargeable lithium battery comprises a porous or micro-porous inert, multi-layered polymer separator laminate which carries an adherent second polymer coating containing a dissociable lithium compound, and the multi-layered separator having adherent solid second polymer layer, is impregnated with an organic liquid containing another lithium salt. The porous or micro-porous separator laminate is made of multiple polymer layers, at least one of the member layers having melting temperature at least 20-C below the melting temperature of the other polymer member layers. The composite porous electrolyte is inserted between the electrodes of a rechargeable lithium battery. In another embodiment the porous polymer separator sheet has an adherent, dissociable lithium compound containing, solid second polymer layer on each of its major faces.
