Lithium-ion batteries (LIBs) and supercapacitors (SCs) are two promising electrochemical energy storage systems and their consolidated products, lithium-ion capacitors (LICs) have received increasing attentions attributed to the property of high energy density, high power density, as well as long cycle life by integrating the advantages of LIBs and SCs.
Two popular energy storage devices that are often compared are batteries and capacitors. A battery is an electrochemical device that stores and releases energy through chemical reactions. It consists of one or more cells, each containing a positive and negative electrode immersed in an electrolyte solution, separated by a membrane.
Based on the energy conversion mechanisms electrochemical energy storage systems can be divided into three broader sections namely batteries, fuel cells and supercapacitors.
When it comes to circuits and electronic devices, energy is typically stored in one of two places. The first, a battery, stores energy in chemicals. Capacitors are a less common (and probably less familiar) alternative. They store energy in an electric field. In either case, the stored energy creates an electric potential.
Capacitor: A capacitor stores energy in an electric field. It consists of two conductive plates separated by a dielectric material. Capacitors can rapidly charge and discharge energy. They have a lower energy density compared to batteries, but they can deliver high power bursts.
In batteries and fuel cells, chemical energy is the actual source of energy which is converted into electrical energy through faradic redox reactions while in case of the supercapacitor, electric energy is stored at the interface of electrode and electrolyte material forming electrochemical double layer resulting in non-faradic reactions.
There are three main thermal energy storage (TES) modes: sensible, latent and thermochemical. Traditionally, heat storage has been in the form of sensible heat, raising the temperature of a medium.
