“…126 The reduction 127 The sulfite additives were demonstrated to be more efficient than carbonate additives in PC-based electrolytes. 118 Similarly, other sulfites 118 including vinyl ethylene sulfite (VES), butylene sulfite (BS), [128][129][130] sulfuric esters (SE), sultone (PS and PES), fluorinated sultone (FPS), and 1, 3-benzodioxol-2-one (BO) were reported to show higher reduction voltages in calculations and improved capacity retention in experiments (suggesting better SEI) for PCbased electrolytes. [124][125][126][127][128][129][130][131][132][133][134][135] However, none of these studies went on to further comment if the additives lead to any changes in the chemistry, morphology, and properties of the SEI, such as the density, cohesive energy, solubility, and porosity, which were associated with SEI performance as argued by Tasaki 74 and Takenaka et al 108 More additive examples with relatively larger molecular formula were also investigated and are summarized in Table 2.…”

A passivation layer called the solid electrolyte interphase (SEI) is formed on electrode surfaces from decomposition products of electrolytes. The SEI allows Li + transport and blocks electrons in order to prevent further electrolyte decomposition and ensure continued electrochemical reactions. The formation and growth mechanism of the nanometer thick SEI films are yet to be completely understood owing to their complex structure and lack of reliable in situ experimental techniques. Significant advances in computational methods have made it possible to predictively model the fundamentals of SEI. This review aims to give an overview of state-of-the-art modeling progress in the investigation of SEI films on the anodes, ranging from electronic structure calculations to mesoscale modeling, covering the thermodynamics and kinetics of electrolyte reduction reactions, SEI formation, modification through electrolyte design, correlation of SEI properties with battery performance, and the artificial SEI design. Multiscale simulations have been summarized and compared with each other as well as with experiments. Computational details of the fundamental properties of SEI, such as electron tunneling, Li-ion transport, chemical/mechanical stability of the bulk SEI and electrode/(SEI/) electrolyte interfaces have been discussed. This review shows the potential of computational approaches in the deconvolution of SEI properties and design of artificial SEI. We believe that computational modeling can be integrated with experiments to complement each other and lead to a better understanding of the complex SEI for the development of a highly efficient battery in the future.

“…Whereas the cell with MMDS is more than 98 % from the 4th to the 100th cycle, and this further confirms the superior cycle performances of the cells with MMDS. It is reported that MMDS was added to the electrolyte to participate in the formation process of the cathode electrolyte interface film, and the film may result in the suppression of the electrolyte oxidized decomposition [19,26,27].…”

Diethyl carbonate (DEC) electrolyte decomposition reactions resulting from PF 5 attacked produce HF by several side reaction steps. The resulting HF can dissolve the Mn from spinel-type lithium manganese oxide (LiMn 2 O 4 ). To verify that methylene methanedisulfonate (MMDS) suppress Mn 3+ dissolution mechanism of lithium manganese oxide spinel cathode using methylene methanedisulfonate as electrolyte additive at elevated temperature, a DEC-based electrolyte using MMDS as electrolyte additive is developed in this work. The linear sweep voltammetry (LSV) indicates the start oxidation potential of the electrolyte with 0.5 wt% MMDS is around 3.83 V (vs. Li/Li + ), which is lower than the control (4.12 V). Self-discharge and inductively coupled plasmaatomic emission spectrometry (ICP-AES) reveal that Mn 3+ dissolution from the spinel cathode is hindered. The results of electrochemical impedance spectroscopy (EIS), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy (XPS) demonstrate that MMDS would help to form the stable passivation film, which would effectively suppress to oxidize the control electrolyte solvents and HF generation is suppressed, and result in less Mn 3+ dissolution from the spinel cathode.

“…Their use results in very small irreversible capacity loss upon SEI creation without sacrifices in the stability of electrodes or ionic conductivity, thus extending the life cycle of lithium ion cells. The discharge capacity and cycling performance of PC-based electrolytes containing butyl sultone (BS) have been studied by Xu et al (2007). These authors showed that BS rapidly formed a protective film on the graphite electrode and improved room-temperature battery performance.…”

From aqueous liquid electrolytes for lithiumair cells to ionic liquid electrolytes that permit continuous, high-rate cycling of secondary batteries comprising metallic lithium anodes, we show that many of the key impediments to progress in developing next-generation batteries with high specific energies can be overcome with cleaver designs of the electrolyte. When these designs are coupled with as cleverly engineered electrode configurations that control chemical interactions between the electrolyte and electrode or by simple additives-based schemes for manipulating physical contact between the electrolyte and electrode, we further show that rechargeable battery configurations can be facilely designed to achieve desirable safety, energy density and cycling performance.
