Electrochemical Sources of Power: Batteries
In the all-electric economy projected for the future in the preceding chapter, the very extensive use of electrochemical power sources will become a necessity. There are a large number of applications, ranging in size from the powering of a pacemaker for a heart to the powering of a truck, where large and remote primary power sources cannot be used, nor can electricity be supplied by wires. Electrochemical power sources can provide the electricity for these applications. Emergency, standby power sources, to be used in case of power failure in the primary system, will also have to supply power in the form of electricity. Another area is the storage of “off-peak” electricity. For the most efficient use of a power generating plant, a uniform load distribution over the 24 hours of the day would be needed. This is especially true for breeder atomic reactors, where “off-peak” electricity can have a negative cost. The breeder produces more fuel than it uses, but only when it operates. For the continuous operation of power plants near full capacity, an energy storage system is required to smooth out the hills and valleys of the use pattern, an important use for electrochemical storers.
