抄録

A sutrSOpm resolution electron microscope is used for in-situ study of lithium ion battery. Our developed model battery consists of a LiMn_2O_4 nanowire(NW), both ends of which connect Pt and ILE/LTO/Cu electrodes. Simultaneous observations of charge/discharge by cyclic voltammetry (CV), and electron microscope and diffraction images showed that the NW works reversible even when the cubic spinel structure has transformed into tetragonal due to local excess intercalation.
