OVERVIEW
An alkaline dry cell battery provides stored electrical power on demand. Typical commercially available dry cell batteries are constructed as cylinders. Ceramic membranes consist of metal oxide particles, which are partially fused together to form a material that is solid, rigid, and stable, but is also porous.
This invention provides a planar dry cell battery that uses ceramic membrane technology and is formed of extraordinarily thin films of material. As in most batteries, this battery requires a cathode, an anode, and a separator. Ceramic membrane technology is used to construct the anode, separator, and cathode layers in thin films for optimum transport of electrical charge, thereby providing significant electrical power. The battery includes a pair of conductive collectors on which the materials for the anode and the cathode may be spin coated. The separator is formed of a porous metal oxide ceramic membrane impregnated with electrolyte so that electrical separation is maintained while ion mobility is also maintained. This battery can be easily fabricated using reel-to-reel processing techniques. In addition, conformal coating techniques may be used to fabricate the battery as a part of a shell such as in the case of a computer or a mobile telephone. The entire battery can be made less than 10 microns thick with single cells each providing around 1.5 volts.
KEY BENEFITS
- The battery is constructed to be extraordinarily thin yet can be readily and efficiently manufactured
- Potentially can be stacked in compact assemblies to create high voltage batteries
- May be manufactured in a variety of specialized geometries to potentially produce self-powered devices
- Thin cathodes perform better and are more efficiently recharged
- Very large interface to volume ratio theoretically increases the potential power surge capacity of the battery
