LITFSI-CF1101 Lithium Bis(trifluoromethanesulfonyl)imide Battery Electrolyte Material

Product Overview

Our LITFSI-CF1101 Lithium Bis(trifluoromethanesulfonyl)imide is a premium battery electrolyte material engineered for high-performance lithium-ion batteries (LIBs) and next-generation battery systems. With ultra-high purity (≥99.95%) and exceptional electrochemical stability, this product serves as a key lithium salt or additive in electrolytes, delivering superior ion conductivity, wide operating temperature range, and excellent compatibility with advanced electrode materials.

Key Features

  1. Lithium bis(trifluoromethylsulfonyl)imide is mainly used in organic-system lithium batteries and antistatic agents. Thanks to the strong covalent bonds of its organic anion, it exhibits excellent thermal stability.
  2. It is used in the lithium battery industry, with conductivity comparable to that of LiClO₄ and LiAsF₆—while eliminating concerns about stability and safety. When used as an additive salt in secondary lithium battery electrolytes, it can effectively improve the electrolyte’s performance.
  3. It can also serve as a synthetic raw material for antistatic additive ionic liquids. These ionic liquids are compatible with various high-performance polymer materials, including thermoplastic and thermoset types.

Product Transportation, Usage & Storage

  1. This product is safe for transportation when packaged intact.
  2. During transportation, protect it from water, moisture, and direct sunlight (note: “防爆晒” is commonly translated as “protect from direct sunlight” in logistics contexts, as “explosion-proof against sunlight” is not standard terminology).
  3. After opening the package, use the product in a glove box or a dry room with a dew point below -55°C.
  4. If the package is accidentally damaged by water, dispose of it immediately.
  5. Store in a cool, ventilated, and dry place. Shelf life is 12 months (unopened).
