Product Overview

This product is a high-purity specialty chemical developed specifically for the field of new energy batteries, especially lithium-ion batteries and lithium sulfur battery systems. It is produced through advanced distillation, purification, and ultra clean filtration technologies, strictly controlling the metal ion content and moisture, meeting the stringent requirements for ultra-high purity and consistency in battery material synthesis and electrolyte additives. Mainly used as a sulfurizing agent for positive electrode material precursors, solid electrolyte intermediates, and electrolyte functional additives.

Product Features

Ultra high purity: Extremely low metal ion and moisture content to avoid negative effects of impurities on the electrochemical performance of the battery, such as self discharge, gas production, and capacity decay.

Excellent vulcanization efficiency: The molecular structure contains two sulfur atoms, and the sulfurization reaction is highly active under relatively mild conditions.

Good batch stability: Strict production process control and comprehensive quality inspection ensure highly consistent product performance.

Professional packaging: Special steel cylinders or high-purity chemical drums with inert gas protection and internal coating are used to prevent contamination and moisture absorption.

Scope of application

Positive electrode material vulcanizing agent: A key sulfurizing agent used for synthesizing high-capacity sulfurized polyacrylonitrile (SPAN) cathode materials for lithium-ion batteries, and can also be used for precursor preparation of other metal sulfide cathode materials.

Solid electrolyte precursor: As an important sulfur source and reaction medium for synthesizing sulfide based solid electrolytes such as Li ₆ PS ₅ Cl, Li ∝ PS ₄, etc.

Electrolyte functional additives: Adding trace amounts of DMDS to conventional liquid electrolytes can form a dense and stable SEI film on the surface of negative electrodes (such as silicon-based negative electrodes), suppress electrolyte decomposition and volume expansion, and improve battery cycle life.

Other electronic chemistry: Can be used for doping, deposition and other processes in semiconductor technology.
