A simple yet detailed explanation of the functions and the necessary characteristics of each component in a lithium-ion battery is provided.
Among various battery technologies, lithium-ion batteries (LIBs) have attracted significant interest as supporting devices in the grid because of their remarkable advantages, namely relatively high energy density (up to 200 Wh/kg), high EE (more than 95%), and long cycle life (3000 cycles at deep discharge of 80%) [11, 12, 13].
Since 2010, more and more utility-scale battery storage plants rely on lithium-ion batteries, as a result of the fast decrease in the cost of this technology, caused by the electric automotive industry. Lithium-ion batteries are mainly used.
