Abstract
A container containing a fluorinated organic carbonate and a gas atmosphere which contains a cover gas selected from the group consisting of a noble gas, e.g., argon, xenon, a gaseous fluorinated aliphatic carbon which is heavier than air and does not interfere with the fluorinated organic compound, SF6, and any mixture thereof. Fluorinated organic carbonates are highly suitable as solvents or additives for solvent in Li ion batteries and consequently, must be kept in a very pure state even during expanded times of storage. The argon or xenon gas atmosphere prevents the intrusion of air or moisture even if the container is opened and the liquid handled in an environment of common air. A method of storing one or more fluorinated organic carbonates in a safe manner.
