Product Introduction
1,3,6-hexanetrinitrile is an important electrolyte additive. The composition of the electrolyte limits the application of positive and negative electrode materials at high voltage. Traditional organic carbonates decompose at high voltage. Nitrile organic solvents typically have excellent characteristics such as wide electrochemical windows, high anode stability, low viscosity, and high boiling point. In addition, organic solvents containing nitrile groups typically decompose into carboxylates, aldehydes, or corresponding organic amines, There will be no generation of highly toxic CN- ions during use.
Application of     hexane-1,3,6-tricarbonitrile
With the development of technology and the increasing demand for mobile devices, the demand for electrochemical devices (such as lithium-ion batteries) has significantly increased. Lithium ion batteries with high energy density, excellent lifespan, and cycling characteristics are one of the research directions. The theoretical capacity of lithium-ion batteries can vary with the type of negative electrode active material. As the cycle progresses, lithium-ion batteries typically experience a decrease in charging/discharging capacity, leading to a deterioration in their performance. In recent years, in the manufacturing of lithium-ion batteries, more and more attention has been paid to the use of water-based slurry compositions as dispersion media to reduce environmental burden. However, the presence of bubbles in the slurry composition can cause multiple pinholes, pits, and other defects in the active material layer, thereby affecting the cycling and high-temperature storage performance of electrochemical devices. Therefore, the CN111129498A patent has developed an electrochemical device and an electronic device containing ethylene carbonate, methyl ethyl carbonate, propyl propionate, nitrile, ethylene glycol di (2-cyanoethyl) ether, 1,2,3-tris (2-cyanoethoxy) propane, propylene carbonate, and ethyl propionate in the electrolyte of the electrochemical device γ- Butanelactone, adipic nitrile, 1,3,6-hexanetrinitrile, lithium difluorophosphate.
