Over the past few decades, lithium-ion batteries (LIBs) have emerged as the dominant
As a mature technology, the battery energy storage system (BESS) is flexible, reliable, economical, and responsive for storing energy [8, 9]. However, with the increasing penetration of renewable energy and the gradual phase-out of grid connections, long-duration energy storage has become significantly more important [ 10, 11 ].
The current market for grid-scale battery storage in the United States and globally is dominated by lithium-ion chemistries (Figure 1). Due to tech-nological innovations and improved manufacturing capacity, lithium-ion chemistries have experienced a steep price decline of over 70% from 2010-2016, and prices are projected to decline further
For example, if a lithium-ion battery has an energy efficiency of 96 % it can provide 960 watt-hours of electricity for every kilowatt-hour of electricity absorbed. This is also referred to as round-trip efficiency. Whether a BESS achieves its optimum efficiency depends, among others, on the Battery Management System (BMS).
