This work shows that pulse current (PC) charging substantially enhances the cycle stability of commercial LiNi 0.5 Mn 0.3 Co 0.2 O 2 (NMC532)\/graphite LIBs. Electrochemical diagnosis unveils that pulsed current effectively mitigates the rise of battery impedance and minimizes the loss of electrode materials. Operando and ex situ Raman and X\u2010ray absorption spectroscopy reveal the chemical and structural changes of the negative and positive electrode materials during PC and constant current (CC) charging. Specifically, Li\u2010ions are more uniformly intercalated into graphite and the Ni element of NMC532 achieves a higher energy state with less Ni\u2500O bond length variation under PC charging. Besides, PC charging suppresses the electrolyte decomposition and continuous thickening of the solid\u2010electrolyte\u2010interphase (SEI) layer on graphite anode. These findings offer mechanistic insights into Li\u2010ion storage in graphite and NMC532 and, more importantly, the role of PC charging in enhancing the battery cycling stability, which will be beneficial for advancing the cycling protocols for future LIBs and beyond.<\/p>\n","protected":false},"excerpt":{"rendered":"<h4>DOI:<\/h4>\n<div class=\"b-doi\">10.1002\/aenm.202400190<\/div>\n<h4>Authors:<\/h4>\n<div class=\"b-author\">Jia Guo, Yaolin Xu, Moritz Exner, Xinrong Huang, Yongchun Li, Yanchen Liu, Hui Wang, Julia Kowal, Qi Zhang, Peter Kj\u00e6r Kristensen, Deyong Wang, Kjeld Pedersen, Leonid Gurevich, Daniel\u2010Ioan Stroe, Philipp Adelhelm<\/div>\n<h4>Abstract:<\/h4>\n<div class=\"b-intro\">Abstract The key to advancing lithium\u2010ion battery (LIB) technology, particularly with respect to the optimization of cycling protocols, is to obtain comprehensive and in\u2010depth understanding of the dynamic electrochemical processes during battery operation.
