“…[4][5][6] However, charging LiNi 0.5 -Mn 1.5 O 4 cathode to high voltages (above 4.5 V vs. Li/Li + ) is always accompanied by significant decomposition of the electrolyte, forming a highly resistive surface film on the cathode, which results in relatively sluggish kinetics of the electrode, and thus leads to the capacity fading in the following cycles. [2][3][4][5][6] Many efforts have been proposed to inhibit the detrimental reactions on the high-voltage cathode materials, including surface modification of LiNi 0.5 Mn 1.5 O 4 with metal compounds such as ZnO, AlF 3 , ZrO 2 , ZrP 2 O 7 , SiO 2 , BiOF. [6][7][8][9][10] The surface modification method improves the cyclic stability but sacrifices the discharge capacity of the high-voltage materials, and these inorganic compounds tend to act as an inert layer to ionic conduction.…”

The performance of the Li/LiNi 0.5 Mn 1.5 O 4 cells cycled to 5.0 V (vs. Li/Li + ) using 1.0 M LiPF 6 -EC/DMC (1/1, v/v) with and without dimethoxydiphenylsilane (DDS) at 25°C has been investigated. Cells with 1% DDS added deliver slightly lower initial discharge capacity than the cells with baseline electrolyte, 115.3 vs. 120.9 mAh g −1 . Electrochemical methods and ex-situ analytical techniques, including TGA and SEM, are employed to conduct the interfacial chemistry of LiNi 0.5 Mn 1.5 O 4 /electrolyte to better understand the improved electrochemical performances of the cells with introduction of DDS. The results indicate that DDS can be electro-oxidized and participates in the formation of the surface layer on cathode electrode, which prevents electrolyte from further decomposition and promotes Li + conduction of the cathode/electrolyte interphase, thus improves the electrochemical performances of Li/LiNi 0.5 Mn 1.5 O 4 cells.

(NMC111)/graphite and Li [Ni 0.42 Mn 0.42 Co 0.16 ]O 2 (NMC442)/graphite pouch cells demonstrate superb performance when ternary blends of electrolyte additives are added to the cells. These ternary blends contain one of vinylene carbonate (VC) or prop-1-ene-1,3-sultone (PES) plus a sulfur containing molecule and tris(trimethylsilyl) phosphite (TTSPi). Here, the excellent charge-discharge capacity retention of cells containing these ternary blends of additives is demonstrated at both 45 • C and 55 • C by comparison to cells with only VC or PES additives alone. The impact of a number of sulfur-and phosphorous-containing electrolyte additives on the reactivity of charged electrode materials with electrolyte at elevated temperatures was studied using accelerating rate calorimetry (ARC). The electrolyte additives, methylene methanedisulfonate (MMDS) and TTSPi, dramatically reduce the reactivity between lithiated (charged) graphite and electrolyte. Lithium-ion cells used in electrified vehicles require longer calendar and cycle lifetime than those used in portable electronics (e.g. laptops and cell phones). In addition, cell used in electrified vehicles can reach high temperatures, so improved tolerance of Li-ion cells to high temperature exposure is also desired. One method of extending lifetime and temperature tolerance of Li-ion cells is to use electrolyte additives in order to suppress parasitic reactions between charged electrodes and electrolyte.1,2 Vinylene carbonate (VC), a popular electrolyte additive, has been shown to improve Li-ion cell performance. 3,4 Recently, some novel sulfur-containing and phosphorouscontaining electrolyte additives have also been shown to be able to increase lifetime, control impedance growth and suppress gas production, etc. for Li-ion cells. Xia et al. 5 showed that the addition of ethylene sulfate (DTD) or trimethylene sulfate (TMS) to Li[Ni 1/3 Mn 1/3 Co 1/3 ]O 2 (NMC111)/graphite pouch cells could increase coulombic efficiency (CE) and decrease impedance after cycling compared to cells without additives. Methylene methanedisulfonate (MMDS) has been shown to be able to greatly decrease the impedance of NMC111/graphite cells after cycling and slow the rate of parasitic reactions at the Li x MO 2 electrode according to storage results.6 Xia et al.7 also showed that prop-1-ene-1,3-sultone (PES) could increase CE, decrease charge end point capacity slippage and suppress gas production during cycling for NMC111/graphite pouch cells. Sinha et al. 8 showed that the CE of NMC111/graphite pouch cells was improved and impedance was reduced when tris(trimethylsilyl) phosphate (TTSP) or tris(trimethylsilyl) phosphite (TTSPi) was added to the electrolyte. In a massive study of over 110 electrolyte additive combinations tested in NMC111/graphite pouch cells, Wang et al. showed that ternary electrolyte additive blends containing one or more of VC or PES, one or more of DTD, MMDS, ES or TMS and one or more of TTSP or TTSPi led to cells with excellent performance.
