Batteries bobbin-type cylindrical

The model 2/3A batteiy is a cylindrically shaped bobbin-type battery, 1.6 cm in diameter and 5 cm long. The battery is a solid cathode type with a nominal 3.0 volt rating. It has low to moderate power capability. The battery is not pressurized and doesn t need a hermetic seal. It is generally used for portable electronic equipment, photographic equipment, watches, calculators, etc. Lifetimes of up to 10 years are obtained.

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... 

The LiMnOj battery is the most popular lithium battery, and it is produced worldwide by more than 14 manufacturers. The battery cells are available in a wide range of sizes, shapes, and capacities. Types of construction features for this battery include coin shape, cylindrical bobbin, cylindrical wound, cylindrical D cell configuration, and prismatic feature. Performance characteristics of commercially available LiMn204 rechargeable batteries are summarized in Table 8.2. 

The performance of the Li/MnOj cylindrical bobbin battery at temperatures from -20 to 60°C is shown in Fig. 14.50. Operation of the coin-type and cylindrieal bobbin eleetrode batteries at the lower temperatures is limited to the lower diseharge rates.
