Techniques to Improve Battery Performance in Terms of Weight and Cost

1 Techniques to Improve Battery Performance in Terms of Weight and Cost 

Performance Parameter Batteries for Typical Lead-Acid Battery 

The data presented in Table 1.3 are the estimated values of the parameters that are accurate within 10%. The manufacturing techniques for Pb-acid batteries are highly optimized and the key electrochemical contents lead and sulfuric acid are inexpensive, whereas the non-Pb-acid-type batteries are continuously undergoing design variations because of changes in material technology and material costs. 

Prediction of battery life is not only difficulty but also expensive. Furthermore, the battery life is dependent on the number of charge and discharge cycles, materials used, and operation type (intermittent or constant). For starting, lighting, and ignition (SLI) applications, prediction of Pb-acid battery life is relatively simple, because the Pb-acid battery design is fully matured and the material cost and maintenance procedures are fully known. In case of batteries using solid electrodes and exotic solid-state materials, prediction of battery life is more complex. As stated earlier, prediction life is strictly dependent on the materials used for the cathodes and anodes, properties of the materials, and the maintenance procedures and schedules used. 

In some critical applications such as reconnaissance satellite or covert communication, satellite redundancy must be considered. This requires a system component, such as a battery charge controller, which is considered the smallest unit, to provide the redundant function necessary to achieve continuous operation aboard the satellite.
