Modification of Nitrate Ion Enables Stable Solid Electrolyte Interphase in Lithium Metal Batteries.
Li-Peng Hou,Nana Yao,Jin Xie,Peng Shi,Shubin Sun,Cheng-Bin Jin,Quanbing Liu,Bo Li,Xue-Qiang Zhang,Qian-Kui Zhang +9 more
TL;DR: In this paper , a modification of nitrate ion (NO3-) is proposed and validated to improve the homogeneity of SEI in practical LMBs, where NO3 is connected to an ether-based moiety to form isosorbide dinitrate (ISDN) to break the resonance structure of NO3- and improve the reducibility.
