2 results about "Chlorinated solvents" patented technology

The application belongs to the technical field of secondary batteries, and more particularly relates to a low-temperature microemulsion electrolyte, a preparation method and application thereof. The low-temperature microemulsion electrolyte comprises an electrolyte salt, a symmetrical cyclic ether solvent, a highly chlorinated solvent insoluble in the symmetrical cyclic ether solvent, and a chlorinated ether solvent for dispersing the highly chlorinated solvent in the symmetrical cyclic ether solvent in the form of micelles. Through synergistic effect of the components, an electrolyte system with high ion conductivity, electrode interface stability and wide temperature range adaptability is constructed, effectively solving the core problems of kinetic sluggishness, poor interface stability and short cycle life of the secondary battery in an ultra-low temperature environment. The electrolyte remains liquid at -70 DEG C, and exhibits excellent cycle stability in a wide temperature range of -40 DEG C to 25 DEG C, giving the battery excellent wide temperature range adaptability, breaking the low-temperature performance bottleneck of the secondary battery, and having a broad application prospect.
