NINGBO INNO PHARMCHEM CO.,LTD. is at the forefront of developing advanced materials for energy storage, with a particular interest in enhancing the performance and safety of sodium-ion batteries (SIBs). One promising avenue of research involves the exploration of alternative electrolyte systems, moving away from conventional flammable organic carbonates. The Sodium Bis(oxalato)borate (NaBOB) salt dissolved in Triethyl Phosphate (TEP) solvent presents a compelling non-flammable and fluorine-free electrolyte solution, showing significant potential for high-temperature SIB applications.

Traditional electrolyte systems often rely on volatile and flammable carbonate solvents, posing safety risks, especially at elevated operating temperatures. The NaBOB-TEP system offers a notable advantage in this regard. However, the inherent solubility limitations of NaBOB in TEP have historically capped its concentration and, consequently, its electrochemical performance. This is where electrolyte additives become critical. The incorporation of additives like Prop-1-ene-1,3-sultone (PES) has demonstrated a marked improvement in the cycling stability and overall performance of NaBOB-TEP electrolytes in SIBs, even under demanding high-temperature conditions (e.g., 55°C).

The synergy between NaBOB and TEP, enhanced by PES, allows for the formation of stable interphase layers on the electrodes, which is vital for preventing parasitic reactions and maintaining capacity retention over extended cycling. This formulation not only addresses the safety concerns associated with flammability but also provides a more robust electrochemical interface, contributing to the overall sodium ion battery stability improvement.

Furthermore, studies suggest that the NaBOB-TEP electrolyte with PES exhibits a lower self-discharge rate compared to conventional carbonate-based electrolytes. This means that batteries utilizing this system can maintain their charge for longer periods when idle, a valuable characteristic for practical applications. The reduced gas evolution observed with PES also contributes to improved cell safety and longevity.

For those seeking to purchase advanced electrolyte components for SIB development, understanding the benefits of the NaBOB-TEP system with appropriate additives is essential. NINGBO INNO PHARMCHEM CO.,LTD. is actively involved in providing these cutting-edge materials. The potential for these non-flammable electrolytes to operate effectively at higher temperatures without significant degradation makes them highly attractive for future energy storage solutions. Exploring the optimal buy/purchase strategies for these components will be key to their successful commercialization and widespread adoption.
