While batteries can provide valuable short-term support to the grid, they cannot function as long-duration energy storage (LDES) solutions or scale to the levels needed to back up large-scale energy systems that are reliant on intermittent wind and solar.

The capacity of these batteries can range significantly, usually falling between 10 to 100 kWh, leading to a higher cell count due to the configuration required for effective energy management.
