These materials are limited in their usage of larger-scale energy storage applications owing to their low working temperatures [214]. Although they are ubiquitous in electronics applied to capacitors, owing to their ease of processing and low costs, academic researchers have studied new configurations, materials, and processes to increase the
A battery energy storage system (BESS) is an electrochemical device that charges (or collects energy) from the grid or a power plant and then discharges that energy at a later time to provide electricity or other grid services when needed. Several battery chemistries are available or under investigation for grid-scale applications, including
Among all the criteria for the large-scale elec. energy storage systems (EESSs), low cost ($ k Wh-1) is the focus where MnO2-based electrochem. can be a competitive candidate.

1. Introduction Renewable energy has been used by humanity for several millennia. In fact, hydro, wind, solar and biofuel power were the only available energy sources during the ancient times. The Industrial Revolution in the 18th century has opened a
Other Ideas. Briefly, two other potential ways to store energy on a large scale are flywheels and a smart grid. The concept behind flywheels is fairly simple in that it is just the conversion of electrical energy to rotational kinetic energy for storage and then conversion back to electrical energy using a generator for extraction.
