The advancement of supercapacitor technology is intricately linked to the development of sophisticated electrolyte materials. Tetraethylammonium Tetrafluoroborate (TEABF4) stands out as a critical electrolyte salt, and understanding its chemical behavior is key to optimizing supercapacitor performance. NINGBO INNO PHARMCHEM CO.,LTD., a leading manufacturer of high-purity chemicals, sheds light on the chemistry behind this essential compound. Tetraethylammonium Tetrafluoroborate, identified by its CAS number 429-06-1, is an ionic compound formed by the tetraethylammonium cation (C8H20N+) and the tetrafluoroborate anion (BF4−). This ionic structure is fundamental to its function as an electrolyte. In solution, TEABF4 dissociates into these mobile ions, which are responsible for charge transport between the electrodes of a supercapacitor. The mobility and stability of these ions directly influence the electrolyte's ionic conductivity and the overall performance of the supercapacitor. One of the most significant chemical attributes of TEABF4 is its inherent stability. The tetrafluoroborate anion (BF4−) is known for its chemical inertness and resistance to electrochemical decomposition within a certain voltage range, contributing to the wide electrochemical window of electrolytes formulated with TEABF4. This is crucial, as a wider electrochemical window allows the supercapacitor to operate at higher voltages, thereby increasing its energy density. Furthermore, the tetraethylammonium cation (C8H20N+) plays a role in ion transport. While larger than smaller alkali metal cations, its structure contributes to good solubility in organic solvents, facilitating the formation of conductive electrolyte solutions. The interaction between these ions and the solvent, as well as their behavior at the electrode-electrolyte interface, are critical areas of study for electrolyte optimization. The chemical specifications provided by manufacturers like NINGBO INNO PHARMCHEM CO.,LTD. are vital for understanding the material’s suitability. The high purity (≥99.0%) ensures that the electrolyte composition is as intended, minimizing interference from unwanted chemical species. Low moisture content (≤200 ppm) prevents unwanted hydrolysis reactions that could degrade the BF4− anion and generate corrosive species like HF. Similarly, the absence of metallic impurities and free acid further ensures chemical integrity. When considering TEABF4 for supercapacitor electrolytes, it is often paired with polar organic solvents such as propylene carbonate (PC) or acetonitrile (ACN). The choice of solvent impacts the solubility of TEABF4, the viscosity of the electrolyte, and its overall conductivity. Manufacturers provide TEABF4 in forms suitable for dissolution, ensuring ease of integration into electrolyte preparation processes. For researchers and manufacturers looking to buy Tetraethylammonium Tetrafluoroborate, understanding its chemical properties is the first step towards successful application.
