Round-trip efficiency is the ratio of useful energy output to useful energy input. (Mongird et al., 2020) identified 86% as a representative round-trip efficiency, and the 2022 ATB adopts this value. In the same report, testing showed 83-87%, literature range of 77-98%, and a projected increase to 88% in 2030.

August 13, 2021. by James Wright, with CIBC Capital Markets in Chicago. Banks have been ready to finance batteries for a while, but until recently, they had not seen many deals come across their desks in need of financing. The market is changing rapidly. First, the basic economic case for them had been marginal until recently.
