It is mainly used as electrolyte additive for power lithium-ion battery. It improves the low temperature performance of the electrolyte and enhance the cycle performance. Improve flash point and have good flame retardancy.

For samples, opened only in dry atmosphere (glove box or dry room), sealed again and stored in cool and dry place after used. For products, packed in stainless steel drum, it should be pressured out under positive pressure in drum and transported by coupling the plug on drum with the socket equipped on flexible pipe.

Package and Storage
The product is packed in stainless steel drum which equipped quick coupler and filled with nitrogen gas in inner, net weight 20KG or 200KG per drum. Samples are packed in fluorinated bottle or stainless steel bottle or aluminum bottle which is wrapped outside with aluminum foil pack.
The product is strictly forbid exposing to the sun. When keep tightly storing in cool and dry place below 25℃ ambient temperatures, it has a shelf life of six months from date of production.
