“…Previously, various approaches have been developed to improve the safe operation of LIBs, including electrolyte additives [3], room temperature ionic liquids [4], composite electrodes [5] and new separator designs [6,7]. Among these methods, modification of separators is straightforward and non-chemical with minimum possible degradations to the original battery operations as compared with other chemical approaches.…”

Lithium ion batteries have gained increasing attention in the last two decades. Perfoming electrolyte additive into lithium ion battery could enhance the baterry performance. However several studies on electrolyte additive only show the experimental data. The behavior of battery kinetic inside the battery and the ionic diffusion during operation was not analyzed. This study will investigate the effect of electrolyte additive on ionic diffusion of battery based on electrochemical model. The role of the electrolyte is to provide an ionic conduction path between the anode and the cathode. This study elucidates the improvement of the cycleability by performing the electrolyte containing 0.1 wt % of Flouro-ophenylenedimaleimide (F-MI) based additive compared to the electrolyte with 0.1 wt % N,N'-o-phenylenedimaleimide (O-MI) and without an additive shown by effective constant phase elements (CPE) coefficient of impedance spectra on electrochemical impedance spectroscopy (EIS). The result elucidates that many amount of lithium ion remains on SEI layer of the mesocarbon microbeads (MCMB) half cell with F-MI additive, indicating that ion move easily because of high diffusion. The simulation result elucidated the agreement with the experimental data, the diffusion of the MCMB half-cell with F-MI additive is highest compared to MCMB half-cell with O-MI and without additive, that is emphasized with result on the EIS test.

“…The use of additives in a liquid electrolyte is considered to be an economic and effective way to enhance the performance of LIBs, by performing various functions, such as film-formation, protection of electrodes, , stabilizing and increasing cycle life, , and flame-retardation , during repeated charge and discharge processes. Ionic liquids (ILs) have been extensively used as a new solvent or additive − of electrolyte for LIBs because of their attractive properties, including high thermal and chemical stability, negligible vapor pressure, reasonably high conductivity, and nonflammability .…”

A novel electrolyte system blending ionic liquid (IL)-decorated PMMA nanoparticles with 1 M LiTFSI dissolved in a mixture of propylene carbonate (PC) and methyl acetate (MA) is reported. With the addition of PMMA-IL-TFSI, this electrolyte exhibits an ionic conductivity of 9.15 × 10–4 S cm–1 even at −40 °C. The improved ionic conductivity at low temperature is attributed to the liquid component in the electrolyte and the unique grafting structure of IL groups on PMMA nanoparticles. Furthermore, it is proved that the presence of PMMA-IL-TFSI can improve the reversible capacity and rate capability of Li4Ti5O12 (LTO)/Li half cells at low temperature. In addition, the morphology change and the electrochemical impedance spectroscopy (EIS) results indicate that the enhancement in battery performances is mainly attributed to the increase of ion conduction via the formation of a stable and effective SEI film on the electrode. These attributes enable the developed PMMA-IL-TFSI-based electrolyte to be a potential ingredient in high-performance lithium-ion batteries at low temperature.
