abstract = {The electrochemical and thermal stabilities of commonly
used LiPF6/organic carbonate-based electrolytes are still a
bottleneck for the development of high energy density
lithium-ion batteries (LIBs) operating at elevated cell
voltage and elevated temperature. The use of intrinsic
electrochemically stable electrolyte solvents, e.g. sulfones
or dinitriles, has been reported as one approach to enable
high voltage LIBs. However, the major challenge of these
solvents is related to their poor reductive stability and
lack of solid electrolyte interphase (SEI)-forming ability
on the graphite electrode. Here,
3-methyl-1,4,2-dioxazol-5-one (MDO) is synthesized and
investigated as new highly effective SEI-forming electrolyte
additive which can sufficiently suppress electrolyte
reduction and graphite exfoliation in propylene carbonate
(PC)-based electrolytes. With the addition of only 2 wt $\%$
MDO, LiNi0.5Mn0.3Co0.2O2 (NMC532)/graphite full cells
containing a 1 M LiPF6 in PC electrolyte reach a cycle life
of more than 450 cycles while still having a capacity
retention of $80\%.$ In addition, MDO has proven to be
oxidatively stable until potentials as high as 5.3 V vs
Li/Li+. Further development of MDO and its derivatives as
electrolyte additives is a step forward to high voltage
stable electrolyte formulations based on alternative
electrolyte solvents and high energy density LIBs.},
