“…An additional peak is observed at ~1.6 V is likely from the reduction of the hydroxyl groups of the PAA and CMC binders. The cell cycled with 10% of added MEC contains an additional new peak at ~1 V, which is likely due to the reduction of MEC, forming poly(MEC) as previously reported [8]. The electrode cycled with standard electrolyte has rapid capacity fade to 1500 mAh/g, corresponding to 46% capacity retention (Fig 2d and e), over the first 100 cycles.…”

“…The use of methylene ethylene carbonate (MEC, Fig. 1a) has been previously reported to significantly improve cycling performance of graphite / NCM111 cells at evalavated temperature with no evidence of significant gas evolution [8,9]. The improvement is likely due to the formation of a high concentration of a polycarbonate derived from MEC, poly(MEC), on the electrode surface.…”

Methylene ethylene carbonate (MEC) has been investigated as an alternative additive to fluoroethylene carbonate (FEC) for Si nanoparticle anodes cycled with 1.2 M LiPF 6 /ethylene carbonate (EC) : diethyl carbonate (DEC) (1:1, w/w) electrolyte. The Si electrodes cycled with 10% MEC-added electrolyte exhibit significantly improved capacity retention after 100 cycles compared to standard electrolyte (73% vs 46%). In addition, the Si electrode cycled with MEC additive has less damage from cracking than the standard electrolyte. Ex-situ surface analyses via infrared and X-ray photoelectron spectroscopy reveal a Solid Electrolyte Interphase (SEI) containing a high concentration of a poly(MEC), which is likely responsible for the improved performance of Si anodes.

“…35 Increasing the concentration of MEC to 10% increases the intensity of the peak at 1802 cm −1 , suggesting a higher concentration of poly(MEC). 19,29 Interestingly, the electrodes cycled in a combination of MEC and LiNO 3 have very different IR-ATR spectra compared to electrodes cycled either in MEC or LiNO 3 alone. The spectra of the electrodes cycled with MEC+LiNO 3 are dominated by peaks at 1490, 1450 and 869 cm −1 , 8,9,15,31,33,34 suggesting that Li 2 CO 3 is the main component of the SEI.…”

The performance of Si-graphite/Li cells and Si-graphite/NMC111 cells has been investigated in 1.2 M LiPF 6 /EC:DEC (1/1, w/w) with different electrolyte additives including LiNO 3 , FEC, and MEC. The addition of additives into electrolytes result in a significant improvement in capacity retention compared to the standard electrolyte for Si-graphite/Li cells. The cells cycled with electrolyte containing 0.5 wt% LiNO 3 , 5-10 wt% MEC or 10 wt% FEC have high capacity retention, at least 88%, while the cells cycled with standard electrolyte have lower capacity retention, 64%, after 100 cycles. Investigation of Si-graphite/NCM111 cells reveals that the cells cycled in electrolyte containing 0.5 wt% LiNO 3 have better capacity retention than cells cycled with 10 wt% FEC, 57.9% vs. 44.6%, respectively. The combination of 10% MEC and LiNO 3 further improves the capacity retention of the Si-graphite/NCM111 full cells to 79.9% after 100 cycles which is highest among the electrolytes investigated. Ex-situ surface analyses by XPS and IR-ATR have been conducted to provide a fundamental understanding the composition of the solid-electrolyte interphase (SEI) and its correlation to cycling performance.

“…( 5 ) The change in aging behaviour, which is mainly related to thermal effect, has been discussed before by Belt et al in [20] which focused on battery aging and confirmed that battery performances evolution can be linear or follow the square root of the aging time according to temperature range. This can be related to the fact that temperature influences mainly the electrolyte decomposition and the growth of the SEI layer [2]. Table II presents the identified model parameters from the power-cycling aging test at 55°C.…”

In this work, we highlight the performance recovery phenomenon when aging high-power lithium-ion batteries used in HEV application. This phenomenon consists in the increase on the battery capacity when we stop power-cycling. We demonstrate the dependency of this phenomenon on the stop-SOC value. Keeping battery at a fully discharged state potentially preserves a large amount of charge from the SEI-electrolyte interaction when they are in the positive electrode during rest time. Results from power cycling and combined, calendar/power cycling, aging of a 12 Ah-commercialized Lithium-ion battery at 55°C have been presented and obtained results have been discussed.
