AN INTRODUCTION TO BATTERY ENERGY STORAGE
When a battery is charged or discharged, the internal resistance of the cells causes thermal energy to be released, creating heat that must be properly managed to keep systems in service.
Among the various battery energy storage systems, the Li-ion battery alone makes up 78 % of those currently in use .
Containerized Battery Energy Storage Systems (BESS) are essentially large batteries housed within storage containers. These systems are designed to store energy from renewable sources or the grid and release it when required. This setup offers a modular and scalable solution to energy storage.
Although there are several battery technologies in use and development today (such as lead-acid and flow batteries), the majority of large-scale electricity storage systems utilize lithium-ion chemistry for increased grid resiliency and sustainability.
These limitations associated with Li-ion battery applications have significant implications for sustainable energy storage. For instance, using less-dense energy cathode materials in practical lithium-ion batteries results in unfavorable electrode-electrolyte interactions that shorten battery life. .
