“…Imaging the electrode surface in order to investigate the SEI structure at the particle level and detecting the effect of electrolyte additives has been followed using different techniques such as scanning electron microscopy (SEM) ( Bian et al., 2018 ; Chalasani et al., 2012 ; Hamidah et al., 2019 ; H. Park et al., 2020 ), transmission electron microscopy (TEM) ( Li et al., 2020 ; Mai et al., 2014 ; Nie et al., 2013b ), scanning tunneling microscopy (STM) ( Seidl, 2015 ; Wang et al., 2012 ), and atomic force microscopy (AFM) ( Huang et al., 2018 ; Luchkin et al., 2020 ). Changes that occurred to the morphology, particle size, and arrangement of the SEI layer including electrode volume expansion/shrinkage, crack formation, and delamination during battery operation could be tracked by imaging techniques ( Harks et al., 2015 ).…”

“…Not only that, the size of the SEI itself will also affect its own stability. For example, when Bian et al studied tea polyphenols (TP) as a new reactive electrolyte additive applied to lithium-ion batteries, − they found that the additive TP can remove ethylene carbonate and form a stable polymer. It is concluded that the thickness of the SEI film will affect its own stability, and the additive TP can react with unstable free radicals to form a polymer, which greatly improves the stability of the SEI film.…”

At present, the basic structure and mechanism of solid electrolyte interface (SEI) have been studied based on different models. Although many researchers have observed the characteristics and properties of SEI through various characterization methods, it is still unable to explain its dynamic mechanism of action from the very small microscopic level. Among them, most researchers change the electrochemical performance of batteries by adding additives or material coating. Traditional research methods only state the performance of batteries from the appearance but lack detailed analysis of the electrochemical reaction of batteries during the research process. Based on the analysis of some models established by SEI, this study summarized the analysis of the research angle of SEI film through various characterization methods. The present traditional SEI and artificial SEI are introduced. Finally, the methods to improve the chemical performance of lithium battery and the challenges to solve the problems are summarized and prospected.

“…A typical lithium-ion battery comprises graphite as an anode electrode, a transition metal oxide as a cathode electrode, and an electrolyte consisting of carbonate-based solvents and lithium salt [7][8][9]. Today, graphite is more widely applied as an anode electrode for advanced commercial LIBs owing to its superior electrical conductivity, substantial theoretical capacity (372 mAh g − 1 ), and cost-effectiveness [10][11][12]. One of the most critical challenges of using graphite as an anode electrode is the exfoliation of the graphite structure during cycling.…”

In this study, a novel S-based compound, methyl p-toluene sulfonate (MPTS) has been investigated as film forming additive in Li/graphite cells. According to the density functional theory (DFT) investigation of electron affinity energy of MPTS and carbonate solvents, MPTS has more negative electron affinity energy of -2.17 eV, whilst it is only − 1.03 eV for ethylene carbonate (EC) and − 0.73 eV for dimethyl carbonate (DMC). It confirms the highest reductive activity of MPTS, which was consistent with the CV test result. The physicochemical features of the graphite electrode were studied using Fourier-transform infrared (FTIR) spectroscopy, field-emission scanning microscopy (FESEM), X-ray photoelectron spectroscopy (XPS) analysis, transmission electron microscopy (TEM), The electrochemical tests results showed that the battery with 1.5% wt% MPTS exhibited a low impedance on the electrode interface and remarkable cyclability, maintaining 93.17% of its initial capacity at 0.2 C after 100 cycles, approximately 11% more than the conventional electrolyte. These outstanding performances are ascribed to the preferential absorption of MPTS and the as-created interface. TEM and XPS analysis confirmed that MPTS forms a thinner SEI layer containing sulfur on the graphite electrode, predicted by recommended mechanism via theoretical calculations. This protective sulfur-containing film promotes faster lithium intercalation/deintercalation kinetics via declining the charge transfer resistance.
