Conclusions This review makes it clear that electrochemical energy storage systems (batteries) are the preferred ESTs to utilize when high energy and power densities, high power ranges, longer discharge times, quick response times, and high cycle efficiencies are required.
Electrochemical energy storage technologies include lead-acid battery, lithium-ion battery, sodium-sulfur battery, redox flow battery. Traditional lead-acid battery technology is well-developed and has the advantages of low cost and easy maintenance.
They also intend to effect the potential advancements in storage of energy by advancing energy sources. Renewable energy integration and decarbonization of world energy systems are made possible by the use of energy storage technologies.
4.2.2. Limitations There are currently several limitations of electrical energy storage systems, among them a limited amount of energy, high maintenance costs, and practical stability concerns, which prevent them from being widely adopted. 4.2.3. Expert opinion
