Batteries for stationary standby and for stationary cycling applications Part 6: Alternative electricity storage technologies

As the need for stored electrical energy has grown, the lead-acid battery has been the primary storage component until very recently. Although improvements in lead-acid technology have been made over the years, short life expectancy and poor component reliability have driven energy storage customers in search of longer life and higher reliability storage technologies. New technology batteries have been developed as well as other non-battery storage devices that are meeting the needs for higher energy densities and more reliability. This paper discusses these emerging energy storage technologies and how they are being used in modern energy storage requirements.
