This functionality is essential for mitigating side reactions during charge and discharge cycles, thereby enhancing the overall longevity and capacity retention of the battery cell. We are committed to supplying this material with exceptional purity profiles, ensuring that every batch supports the reliability required by electric vehicle manufacturers and consumer electronics producers.

Technical Specifications

Industrial Applications

The primary application of 1,3,2-Dioxathiolane 2,2-dioxide is within the lithium-ion battery supply chain. It is incorporated into electrolyte solutions to improve thermal stability and ionic conductivity. By facilitating a stable SEI layer, this additive helps prevent electrolyte decomposition and reduces the risk of thermal runaway, which is a critical safety consideration in large-scale energy storage systems.

• Enhances the stability and uniformity of the solid electrolyte interphase (SEI).
• Improves cycle life and capacity retention under high-voltage conditions.
• Contributes to thermal safety and reduced risk of internal short circuits.
• Compatible with various lithium salt concentrations and organic solvent systems.
• Supports fast-charging capabilities by maintaining low impedance growth.

Quality Assurance and Testing

Quality control is paramount in our manufacturing process. Every production batch undergoes comprehensive analytical testing using high-performance liquid chromatography (HPLC) and inductively coupled plasma mass spectrometry (ICP-MS). We strictly monitor impurity profiles, ensuring that metal ions such as Sodium, Potassium, Iron, Zinc, Nickel, Magnesium, Calcium, and Lead are maintained below 1 mg/kg. This level of purity is crucial to prevent catalytic degradation within the sensitive environment of a battery cell.

Storage and Handling

To maintain chemical stability, this product must be stored in airtight containers to prevent moisture absorption, which can lead to hydrolysis. We recommend storage in a cool, ventilated, and dry environment away from direct sunlight and heat sources. Proper handling procedures should be followed in accordance with safety data sheets (SDS) to ensure personnel safety during transfer and formulation processes. Our packaging solutions are designed to protect the integrity of the crystals during global transit.
