For professionals in the battery manufacturing sector, sourcing high-quality electrolyte additives is fundamental to producing reliable and high-performing lithium-ion batteries. Methylene Methanedisulfonate (MMDS), identified by CAS No. 99591-74-9, stands out as a critical component for enhancing battery chemistry. NINGBO INNO PHARMCHEM CO.,LTD., a prominent manufacturer and supplier from China, provides comprehensive information for procurement specialists and R&D scientists looking to integrate MMDS into their advanced battery solutions.

Key Specifications and Properties of MMDS

Understanding the technical specifications of MMDS is crucial for ensuring its optimal performance in lithium-ion battery electrolytes. The typical properties include:

  • Purity: High purity, often ≥99.5% (GC), is essential for consistent electrochemical behavior and to avoid introducing impurities that could degrade battery performance.
  • Appearance: MMDS is commonly supplied as a white to off-white crystalline powder or solid.
  • Melting Point: A distinct melting point, typically in the range of 150-152°C, is a key indicator of its form and purity.
  • Moisture Content: Low moisture levels (≤200ppm, Karl-Fischer) are critical, as water can detrimentally affect electrolyte stability and battery performance.
  • Acidity: Controlled acidity, often measured as HF (≤100ppm), is another important parameter for electrolyte compatibility.

Why Choose MMDS for Your Battery Application?

The primary application for MMDS is as an electrolyte additive in lithium-ion power batteries, particularly those using lithium manganate as the cathode material. Its benefits are directly linked to the formation of a stable SEI film, which translates to:

  • Extended Battery Lifespan: By protecting electrode surfaces and reducing unwanted side reactions, MMDS significantly enhances the cycle life of batteries.
  • Improved High-Temperature Performance: The protective SEI layer contributes to better thermal stability, making batteries more robust under elevated temperature conditions.
  • Enhanced Safety Features: By mitigating electrolyte decomposition and impedance rise, MMDS contributes to overall battery safety and reliability.
