ElectroniCast Consultants estimates that in 2011, the worldwide consumption value of lithium-ion capacitors (LICs) used in solar photovoltaic (PV) power generation applications will reach US$0.862 million; however, consumption value is forecast to increase at an average annual growth rate of 87.5% to US$19.99 million in 2016. From 2016-2021, the total consumption value is forecast to increase 63.4% per year, reaching US$232.88 million in the year 2021. A capacitor is an electrical device that stores or releases electricity through rapid electrostatic reactions. Compared with a battery that stores electricity through slow chemical reactions, a capacitor makes it possible to charge and discharge electricity almost instantaneously with a long cycle life. LICs have a higher power density as compared to batteries and they are safer in use than lithium-ion batteries (LIBs), since thermal runaway reactions may occur with LIBs. Compared to an electric double-layer capacitor (EDLC), the lithium-ion capacitor has a higher output voltage. They both have similar power densities, but energy density of a lithium-ion capacitor is higher. According to ElectroniCast one of the main market driver for LICs with solar (PV) panels will be in conjunction with LED street/roadway lighting. Source: www.digitimes.com
