主　　题：Lithium metal battery Ni-rich cathode Phenyl vinyl sulfone Dendrite 

摘      要：One of the bottlenecks limiting the cycling stability of high voltage lithium metal batteries(LMBs)is the lack of suitable ***,phenyl vinyl sulfone(PVS)is proposed as a multifunctional additive to stabilize both cathode and anode interfaces as it can be preferentially oxidized/reduced on the electrode *** PVS derived solid electrolyte interphase films can not only reduce the transition metal dissolution on the cathode side,but also suppress the Li dendrite spread on the lithium anode *** Li||Li symmetric battery with PVS addition delivers longer cycle life and a higher critical current density of over 3.0 m Ah cm^(-2).The LiNi_(0.8)Co_(0.1)Mn0.1O_(2)(NCM811)||Li full cell exhibits excellent capacity retention of 80.8%or 80.0%after 400 cycles at 0.5 C or 1 C rate with the voltage range of 3.0–4.3 *** particular,the NCM811||Li cell under constrained conditions remains operation over 150 *** work offers new insights into the electrolyte formulations for the next generation of LMBs.
