In the competitive landscape of battery technology, the selection of high-performance chemical components is critical. For manufacturers of lithium-ion batteries (LIBs), understanding the specific properties and benefits of electrolyte additives like Ethylene Glycol Bis(2-cyanoethyl) Ether (DENE, CAS 3386-87-6) is key to product differentiation and performance enhancement. This article delves into the core properties of DENE and explains why it is a preferred choice for advanced battery formulations.

DENE is characterized by its colorless to pale-yellow clear liquid appearance, making it easy to handle and integrate into liquid electrolyte systems. Its molecular formula is C8H12N2O2, with a molecular weight of approximately 168.20 g/mol. The boiling point is recorded at 165 °C at 5 mmHg, and its density is around 1.05-1.07 g/cm³. These physical and chemical properties are crucial for its function within the demanding environment of a lithium-ion battery.

The most significant functional property of DENE is its role as an electrolyte additive that directly impacts battery performance metrics. Firstly, it is known to reduce the internal impedance of LIBs. Lower impedance means less resistance to ion flow, which translates directly into improved rate capability. This allows batteries to deliver more power quickly, essential for applications like electric vehicles and portable electronics. Manufacturers seeking to improve power output will find DENE to be a valuable addition to their electrolyte blends.

Secondly, DENE significantly enhances the cycling performance of LIBs. Studies have shown that electrolytes containing DENE exhibit remarkable cycling stability and capacity retention, even after hundreds of charge-discharge cycles. This improved longevity is attributed to its ability to form a stable solid electrolyte interphase (SEI) on electrode surfaces. This protective layer prevents the undesirable oxidation of the electrolyte and the dissolution of active materials from the electrodes, which are common failure mechanisms that degrade battery life.

Furthermore, DENE is particularly effective at improving the battery's performance at low temperatures. As temperatures decrease, the viscosity of conventional electrolytes increases, hindering ion movement and reducing battery efficiency. DENE helps to maintain electrolyte fluidity and ionic conductivity at lower temperatures, ensuring that batteries can still operate effectively in cold climates or during rapid discharge cycles.

For procurement managers and research scientists, identifying a reliable supplier for high-purity DENE is a priority.
