Description

Application

Lithium tetrafluoroborate (LiBF4) finds application as electrolyte material in lithium ion batteries (LIBs). However, the presence of trace amount of water in LiBF4 causes its hydrolysis which leads to HF generation and destruction of the battery electrodes. Our LiBF4 contains < 100 ppm of water and is well suited for applications in LIBs.

Caution

• These electrolyte solutions have extremely low water content; Please handle under inert and moisture free environment (glove box).
• Keep away from heat, sparks and flame. Avoid moisture, strong acid, strong alkalis, and oxidizing agents. Avoid skin and eye contact from product. Highly toxic and corrosive gases (HF) are generated by reaction with moisture os use only under inert gas atmosphere.
• Please handle under inert and moisture free environment.

Storage:
Keep containers away from heat, humidity, direct sunlight and ignition source. Keep containers tightly closed in a cool dry and well-ventilated place. Do not store with strong oxidizing agents.
