Lithium-ion battery
Energy Storage in Buildings, A Technology Overview (BG 73/2018), written by John Piggott and published by BSRIA in March 2018, sates: ‘Most modern rechargeable batteries are based on a chemical reaction involving lithium in a solid electrolyte compound. Lithium-ion batteries have replaced alkaline batteries as the default energy store in portable devices because they offer a far greater energy density and have a superior charge/discharge cycle efficiency. Many variations of lithium-ion battery are in use, with different chemicals used for the cathode and electrolyte, and different physical structures…. Lithium-ion batteries have a fast response to sudden power demands, which makes them useful for controlling and stabilising the frequency of an electrical supply. Large arrays of these batteries have been installed at strategic locations on the UK electricity network in recent years, to provide voltage and frequency stabilisation.’
