      abstract     = {The key to advancing lithium-ion battery (LIB) technology,
                      particularly with respect to the optimization of cycling
                      protocols, is to obtain comprehensive and in-depth
                      understanding of the dynamic electrochemical processes
                      during battery operation. 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-ray absorption
                      spectroscopy reveal the chemical and structural changes of
                      the negative and positive electrode materials during PC and
                      constant current (CC) charging. Specifically, Li-ions are
                      more uniformly intercalated into graphite and the Ni element
                      of NMC532 achieves a higher energy state with less Ni─O
                      bond length variation under PC charging. Besides, PC
                      charging suppresses the electrolyte decomposition and
                      continuous thickening of the solid-electrolyte-interphase
                      (SEI) layer on graphite anode. These findings offer
                      mechanistic insights into Li-ion 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.},
