Pancake battery

Abstract

Abstract A battery preferably for use as a power source in an electrical vehicle in which the batteries can be disposed across the bottom of the car to form a structural part of the vehicle. Each cell is preferably divided into three chambers - an upper chamber, a middle chamber containing the horizontally mounted battery plates and a lower chamber - so that the electrolyte flows by gravity from the upper chamber through the plates flushing waste products such as water which result from the production of electricity by the battery and which eventually insulate the electrolyte from the plates and prevent further electricity from being produced. After all of the electrolyte has flowed from the upper chamber into the lower two chambers, it can be pumped back to the upper chamber to repeat the journey, either while the vehicle is stopped, by applying a source of compressed air to the lower chamber, or continuously while the vehicle is moving, for example, by pumping the liquid during regenerative braking. The plates can be of any shape or size including circular, and preferably the horizontal plates are disposed at a slight angle to prevent gas produced during charging from building up between the plates. In another embodiment the plates are formed as cones and disposed in a stack in the battery so that the electrolyte flows downward through the cones.
