“…Chemical electronic energy spectrometer was used to measure the batteries under sinusoidal waveform charging and CC-CV charging methods along with the brand-new battery. According to the in-depth analysis of the main components of SEI membrane, such as lithium (Li 1s), oxygen (O 1s), carbon (C 1s), the proportion of the components of SEI membrane in the battery was indicated alongside the fact that the sinusoidal waveform charging method was capable of inhibiting the growth of SEI membrane [1,2,4,6,7,8,10,11].…”
