 Lithium-ion coin cells containing electrolytes with and without 1,3-

propane sultone (PS) and vinylene carbonate (VC) were prepared and investigated.

The electrochemical performance of the cells is correlated with ex situ surface analysis

of the electrodes conducted by Fourier transform infrared and X-ray photoelectron

spectroscopies and in situ gas analysis by online electrochemical mass spectrometry

(OEMS). The results suggest that incorporation of both PS and VC results in

improved capacity retention upon cycling at 55 °C and lower impedance. Ex situ

surface analysis and OEMS confirm that incorporation of PS and VC alter the

reduction reactions on the anode inhibiting ethylene generation and changing the

structure of the solid electrolyte interface. Incorporation of VC results in CO 2

evolution, formation of poly(VC), and inhibition of ethylene generation. Incorporation

of PS results in generation of lithium alkylsulfonate (RSO 2 Li) and inhibition of

ethylene generation. The combination of PS and VC reduces the ethylene gassing

during formation by more than 60%.
