Electrochemical energy storage devices

Abstract

Increasing reliance on renewable energy sources, and technological advances in areas such as electric traction, smart grids and portable electronic gadgets have catalysed renewed interest in electrochemical energy storage options, of both miniature and large scale. The electrochemical mode of energy storage offers flexibility and scalability as well as candidate systems with a range of energy densities. With their low costs and low rates of self-discharge, they are particularly suitable for stationary applications as in power grids that are connected to intermittent renewable energy sources such as wind and solar. In this study, we assess the suitability of both mature and emerging electrochemical storage technologies that can meet the energy requirements of India.
