1,3,6-Hexanetricarbonitrile (HTCN) CAS 1772-25-4 Purity >99.0% (GC) Li-ion Battery Electrolyte Additive

1,3,6-Hexanetricarbonitrile (HTCN) (CAS: 1772-25-4) is an important electrolyte additive. The composition of the electrolyte limits the application of anode and cathode materials at high voltages. Traditional organic carbonates (such as chain carbonates DEC, DMC, EMC and cyclic carbonates PC, EC, etc.) will decompose at high voltages. Therefore, the development of new organic solvents with wide electrochemical window and high solubility and low toxicity to lithium salts has become one of the key points in the development of high voltage electrolytes. Nitrile organic solvents usually have a wide electrochemical window, high anodic stability, low viscosity and high boiling point, etc. With the development and application of Li-ion battery technology, researchers found that the compounds with CN group as electrolyte additive can improve electrochemical performance for Li-ion battery. And some researches carried out their study on HTCN additive. It was found that HTCN as electrolyte additive can broaden the oxidation potential of the electrolyte and enhance the electrochemical performance of the cathode under high operating voltage. Add HTCN into the electrolyte can significantly improve the cycling stability and rate capability of the cathode material. This is mainly attributed to the formation of more stable and effective electrode/electrolyte interface film on the cathode surface. HTCN can also effectively lower the interfacial resistance, suppress the decomposition of the electrolyte.
