Energy batteries

One of the main reasons is the low power density of fuel cells. Power density, defined as power produced per unit weight or unit volume of the power source, is one of the most important factors for a power source for transportation as well as energy density, defined as energy produced per unit weight or volume. As for fuel cells, unlike batteries, energy density would not be such a serious problem as power density because energy density can be increased when more fuel is loaded. 

Apart from the promising electrochemical properties that will be exhaustively discussed through this chapter, carbon nanotubes have become a hot research topic due to their outstanding electronic, mechanical, thermal, optical and chemical properties and their biocompatibility. Near- and long-term innovative applications can be foreseen including nanoelectronic and nanoelectromechanical devices, held emitters, probes, sensors and actuators as well as novel materials for mechanical reinforcement, fuel cells, batteries, energy storage, (bio)chemical separation, purification and catalysis [20].

The alkaline Zn/Mn02 battery is one of well-developed battery systems in the industrial and consumer markets, and is still undergoing continuous developments to improve its performance. The developments include the improvement in active materials and its purity to enhance battery energy capacity the improvement in the cell structure and cell composition to enhance battery power density the improvement in sealing materials and the sealing structure to enhance the battery storage and operational life, and to further prevent leakage.

Many, perhaps most, of recent (since 1980), utility-scale BESSs are presented in Table 10.1. For each BESS, details are given of the location, rated capacity, principle applications, and date of installation. The more familiar systems, i.e., those for which descriptive information is reasonably available, are discussed below. In recent years, the lead-acid battery, energy-storage, and related industries have often been involved in acquisitions and other corporate structure changes such that name changes have taken place. The following discussion uses names that were appropriate when the BESSs came to public attention. 

The BESS at Crescent EMC was originally installed for test purposes at the Battery Energy Storage Test (BEST) facility in New Jersey and underwent some cycling there, perhaps the equivalent of 200 cycles. At Crescent, it is cycled to reduce the demand whenever there is a possibility that Duke Energy will experience their...
