abstract = {Film-forming electrolyte additives are crucial for
establishing the performance and safety of
high-energy-density lithium-ion batteries (LIBs). Thorough
investigation of the solid electrolyte interphase (SEI)
formation and of the decomposition mechanisms of the
additives is needed. In this work, several derivatives of
N-carboxyanhydrides (N-CAs) are synthesized to distinguish
relevant molecular substrate parameters crucial for
polymerization and film formation and evaluated in
LiNi0.8Co0.1Mn0.1O2||Si/graphite cells. Electrochemical
performance and laser desorption/ionization mass
spectrometry analyses are conducted to elucidate underlying
decomposition mechanisms and their dependency on functional
moieties. Incorporation of sterically demanding moieties
showed beneficial cell performance depending on the size of
the functional group. The variation of functionality on the
N-CA core shows an influence on the film formation and the
flexibility of the formed SEI film rendering steric demand
and the electronic properties of a functional group
significant molecular parameters. This study is intended to
enhance the fundamental understanding of influential
substrate parameters of the molecule and to navigate the
direction of research toward a both creative and systematic
approach of electrolyte additive design for
high-energy-density LIB cells.},
