In the contemporary energy landscape, the significance of energy storage systems (ESS) has transcended mere utility; they have become pivotal in ensuring energy sustainability, reliability, and efficiency. By enabling the conversion and storage of electrical energy, thermal energy, or other forms of energy, these systems play a crucial role in balancing supply and demand. The rising global dependence on renewable energy sources — such as solar and wind — has accentuated the need for effective energy storage solutions to manage the intermittency of these sources, thereby enhancing the overall energy infrastructure.

Energy storage solutions can be classified into various technologies. Among them, battery storage is currently the most widely implemented method. This technology capitalizes on the transformation of electrical energy into chemical energy, which is then stored for future conversion back to electricity. The prevalence of lithium-ion batteries in applications ranging from electric vehicles to residential energy systems showcases their significant adoption due to their high energy density, prolonged lifespan, and efficiency. However, the landscape is not limited to lithium-ion alone. Other technologies, including sodium-sulfur batteries, lead-acid batteries, supercapacitors, and compressed air energy storage, contribute to a diverse portfolio of solutions that cater to different energy storage needs.
