Abstract

A storage battery structure is disclosed including electrodes which are moved relative to each other during operation. The electrodes also have areas that are both different in size, with ratios that are variable. The battery structure includes a first electrode which is fixed in a container. An electrolyte material is also included in the container. A second electrode is moved past the fixed electrode in the container and battery action such as discharge occurs between proximate areas of the first and second electrodes. A third electrode may be provided in the container to recharge the second electrode as areas of the second electrode are moved past the third electrode at the same time that other areas of the second electrode are being discharged at the first electrode. Furthermore, the ratio of the third electrode area to the first electrode area is much larger than 1, resulting in a recharge time that is much faster. The improvement in recharge speed is given by that area ratio.

Claims

1. A storage battery structure comprising:

an enclosed container means;

an electrolyte material disposed in said container means;

at least one first type battery electrode disposed in said container means;

at least one second type battery electrode disposed in said container means;

means for moving said at least one second type battery electrode in a path past said at least one first type battery electrode so that a surface of said at least one second type electrode is moved proximately opposite to a surface of said at least one first type electrode, said at least one first type electrode, said at least one second type electrode and said electrolyte means forming a storage battery cell structure when said surfaces of said at least one first type and said at least one second type battery electrodes are moved past each other;

at least one third type electrode disposed proximate to the path of said at least one second type electrode, so that a surface of said at least one second type electrode is moved proximately opposite to said surface of said at least one third type electrode;

and a source of electrical energy connected to said at least one third type electrode wherein said at least one third type electrode functions as a charging electrode.

2. A storage battery structure according to claim 1 wherein said at least one first type electrode has a surface having a surface area A1, said at least one second type electrode has a surface having a surface area A2, said at least one third type electrode has a surface having a surface area A3, and wherein said ratio of said area A3 to area A1 is greater than one and the charging time of said battery is less than the discharging time as a function of the inverse of said ration of said area A3 to area A1.

3. A storage battery structure according to claim 1 further including at least one third type electrode disposed proximate to said to the path of at least one second type electrode, and a source of electrical energy connected to said at least one third type electrode wherein said at least one third type electrode functions to charge said at least one second type electrode proximate thereto at the same time that said at least one first type electrode functions to discharge said at least one second type electrode proximate thereto.

4. A storage battery structure according to claim 1 wherein said at least one of said first, second and third type electrodes are selectively removable from their said locations.
