DENE {1,2-Bis(2-cyanoethoxy)ethane, 99.5%} as High-Voltage Battery Electrolyte Additive, 25 g/bottle, CBEADENE

DENE {1,2-Bis(2-cyanoethoxy)ethane, also called Ethylene glycol bis(propionitrile) ether}, is primarily used as an electrolyte additive for lithium-ion batteries (LIBs), particularly in research for high-voltage and lithium-metal batteries. It facilitates the formation of a stable and uniform SEI layer on the graphite anode, which is crucial for improving the battery's cycle performance and stability. It can also participate in forming a protective film on the cathode, which helps to suppress unwanted decomposition of the electrolyte at high voltages.
