3 Fabrication Aspects of Batteries for Low-Power Electronic Device Applications 

Fabrication of a battery or a cell determines how the device will function and how much it will cost to construct it. Several primary cells with aqueous electrolytes seem to use a single electrodes arranged in parallel or concentric configuration. Specific construction of this type of cell includes cylindrical or bobbin button, and coin. Small secondary cells use a wound or jelly roll construction feature, in which long thin electrodes are wound into a cylinder and placed in a metallic housing or container. This particular cell construction yields higher power density, but it 

4 Performance Capabilities and Limitations of Various Primary and Secondary Batteries for Low-Power Applications 

According to a market survey, C-Zn primary batteries continue to dominate the market on a worldwide basis. They are widely used for most of the electrical and electronic devices requiring power ranging from approximately 50 mW to 15 W. C-Zn primary batteries are widely used because of their exceptionally reliable performance, improved and enhanced shelf life, and significantly reduced leakage. 

There is environmental pressure to remove not only the mercury but also cadmium and lead from the zinc cans. A couple of decades ago, California announced a prohibition on the sale of C-Zn and alkaline cells containing mercury. The restriction on the use of mercury in batteries eliminates the need for recycling, thereby eliminating storage and transportation problems. In other words, the restriction on the use of zinc plus the need to remove mercury would favor the sale
