CHEMISTRY Correction for “Robust high-temperature potassium-ion batteries enabled by carboxyl functional group energy storage,” by Xianlu Lu, Xuenan Pan, Dongdong Zhang, Zhi Fang, Shang Xu, Yu Ma, Qiao Liu, Gang Shao, Dingfa Fu, Jie Teng, and Weiyou Yang, which published August 24, 2021; 10.1073/pnas.2110912118 (Proc. Natl. Acad. Sci. U.S.A. 118, e2110912118).The authors wish to note the following: “With respect to the K+ storage mechanism, the related explanation in the original manuscript on page 4, left column, first full paragraph, lines 17–29 has an error, which should be corrected to make this point clearer.The original expression about the K+ storage mechanism is: ‘Fig. 4C is a schematic illustration of the K+ storage mechanism in the current case. It is known that PTA holds two carboxyl groups per formula unit, which could act as the redox centers to react with two K+….
