NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to advancing energy storage technologies, with a keen focus on sodium-ion batteries (SIBs). A significant area of research and development involves optimizing electrolyte formulations to overcome critical challenges such as high-temperature performance degradation and safety concerns. Among the various additives explored, Prop-1-ene-1,3-sultone (PES) has emerged as a highly promising component for improving SIB performance.

The primary function of PES in sodium-ion batteries is to enhance the stability of the solid electrolyte interphase (SEI) and cathode electrolyte interphase (CEI) layers. These protective layers are crucial for preventing continuous electrolyte decomposition and minimizing irreversible sodium ion loss during the charge-discharge cycles. The intrinsic instability of SEI layers, particularly at elevated temperatures, often leads to rapid capacity fading and reduced battery lifespan. PES, when incorporated into the electrolyte, helps to form a more robust and stable SEI, thereby mitigating these issues. Research indicates that PES can significantly improve cycling stability even at temperatures as high as 55°C, a critical factor for applications in demanding environments.

Furthermore, PES contributes to reducing gas evolution within the battery cell. Excessive gas buildup can lead to increased internal pressure, affecting battery safety and performance. Studies have shown that electrolytes containing PES exhibit lower pressure increases during initial cycling compared to those without additives or with other conventional additives. This property is vital for developing safer, more reliable battery systems. The improved sodium ion battery stability improvement offered by PES makes it a key candidate for next-generation SIBs.

Beyond its protective capabilities, PES also plays a role in developing non-flammable electrolyte systems. This is particularly relevant when used in conjunction with specific electrolyte salts and solvents, such as NaBOB in TEP. Such combinations offer a pathway towards safer battery chemistries, reducing the reliance on volatile organic carbonate solvents that are common in lithium-ion batteries. The ability to achieve enhanced electrochemical performance with non-flammable, fluorine-free electrolytes is a significant step forward in battery safety and sustainability.

For battery manufacturers and researchers looking to push the boundaries of sodium-ion battery technology, understanding the benefits of additives like PES is crucial. NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing high-quality electrolyte components and insights to support this advancement. Exploring the optimal buy/purchase of PES and its synergistic effects with other electrolyte components will be key to unlocking the full potential of SIBs for various energy storage applications.
