Most utility-scale batteries in the United States are made of lithium-ion Most of the utility-scale battery systems used for energy storage on the U.S. electric grid use lithium-ion (Li-ion) batteries, which are known for their high-cycle efficiency, fast response times, and high energy density. Nearly all of the utility-scale battery systems installed in the United States in the past five years use lithium-ion technology.
