Abstract
Lithium-ion battery cells and a lithium-ion utilizing capacitor cells are placed spaced-apart in a common container and infiltrated with a common lithium-ion transporting, liquid electrolyte. The lithium-ion-utilizing capacitor and lithium-ion cell battery are combined such that their respective electrodes may be electrically connected, either in series or parallel connection for energy storage and management in an automotive vehicle or other electrical power supply application.
