Abstract
The present invention is drawn to a high power electrochemical energy storage device, comprising at least one stackable, monolithic battery unit. The monolithic battery unit includes at least two electrochemical energy storage cells. The cells have a lithium ion insertion anode and a lithium ion insertion cathode, a bipolar current collector between cells and end plate current collectors at the opposing ends of each battery unit. A frame may be associated with the perimeter of the current collector. The current collector comprises a high-conductivity metal. The device also has the at least two storage cells substantially aligned adjacent one another, a separator material associated between the anode and the cathode within each cell; and an electrolyte within each cell. Additionally, the present invention is drawn to a device combining two or more of the monolithic units, either in series or in parallel or any combination thereof, so as to create a high power, high voltage energy storage device.
