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
-
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.
-
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.
-
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
- This product is safe for transportation when packaged intact.
- 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).
- After opening the package, use the product in a glove box or a dry room with a dew point below -55°C.
- If the package is accidentally damaged by water, dispose of it immediately.
- Store in a cool, ventilated, and dry place. Shelf life is 12 months (unopened).
