The performance of modern lithium-ion batteries is intricately linked to the sophisticated chemistry of their electrolytes. As researchers and manufacturers continually push the boundaries of energy density, charging speed, and lifespan, specialized electrolyte additives play an increasingly vital role. One such compound gaining prominence is 1,2-Oxathiolan-4-ol, 2,2-dioxide, known by its CAS number 10200-48-3. For those in R&D seeking to buy this chemical or procurement managers aiming to secure a reliable supply, understanding its scientific contribution is key.

As a dedicated manufacturer of high-purity chemicals, we are deeply invested in the science behind our products. 1,2-Oxathiolan-4-ol, 2,2-dioxide functions primarily as a functional additive within the electrolyte of lithium-ion batteries. Its unique molecular structure allows it to interact favorably with electrode surfaces and electrolyte components, thereby enhancing crucial battery characteristics.

The primary scientific contribution of CAS 10200-48-3 lies in its ability to promote the formation of a stable and robust Solid Electrolyte Interphase (SEI) layer. This SEI layer is a passivation film that forms on the surface of the anode (typically graphite or silicon-based) during the initial charging cycles. A well-formed SEI layer is critical for several reasons:

1. Preventing Electrolyte Decomposition: It acts as a barrier, preventing the continuous decomposition of the electrolyte solvent, which would otherwise lead to capacity loss and gas generation over time.

2. Facilitating Ion Transport: While acting as an electronic insulator, the SEI layer must remain ionically conductive to allow Li+ ions to pass through to the anode. 1,2-Oxathiolan-4-ol, 2,2-dioxide helps create an SEI with optimized ionic conductivity.

3. Improving Cycling Stability: A stable SEI layer minimizes irreversible capacity loss during repeated charge-discharge cycles, thereby extending the overall lifespan of the battery.

4. Enhancing Thermal Stability: The presence of this additive can also contribute to improved thermal stability of the battery, reducing the risk of thermal runaway under stressful conditions.

Furthermore, 1,2-Oxathiolan-4-ol, 2,2-dioxide can also contribute to the stability of the cathode interface, playing a role in protecting the cathode material from degradation, particularly at higher operating voltages. This dual-action capability makes it a versatile and valuable additive for various battery chemistries.

For researchers and manufacturers looking to procure this advanced material, our commitment as a China-based supplier is to provide CAS 10200-48-3 with a purity of 99% or higher.
