One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, such as the rate of change in the concentration of reactants or products with time. 123-06-8, Name is Ethoxymethylenemalononitrile, formurla is C6H6N2O.

Realizing a high-performance LiNi0.6Mn0.2Co0.2O2/silicon-graphite full lithium ion battery cellviaa designer electrolyte additive
An optimized dosage of (2-cyanoethyl)triethoxysilane (TEOSCN), is investigated as the electrode/electrolyte interface (EEI) modulating electrolyte additive to improve electrochemical performance of LiN0.6Mn0.2Co0.2O2(NMC622)/silicon(Si)-graphite(Gr) battery cells at a high temperature (45 degrees C). The addition of 1 wt% of TEOSCN to 1 M LiPF(6)in EC:DEC + 5 wt% FEC/2 wt% VC electrolyte is found to significantly improve the long-term cyclability, capacity retention and coulombic efficiency of NMC622/Si-Gr cells at 45 degrees C. Pouch cells cycled in a nitrile-functionalized silane bearing electrolyte show superior capacity retention (similar to 75.95%) compared to those with FEC/VC (similar to 8.05%) and without additives (EC:DEC, similar to 19.23%) electrolytes at the 364(th)cycle. Chemical mimicking and X-ray Photoelectron Spectroscopy (XPS) analysis proved that the enhanced electrochemical performance is attributed to the formation of -C equivalent to N reduction/oxidation induced robust EEI layers, both on the anode and cathode compartments, thus mitigating the escorted prevailing challenges. This work provides a highly promising electrolyte additive enabling the large-scale commercial deployment of Si-containing high-energy lithium-ion full cell batteries.
