Effect of Addition of Fluoroorganic Compounds to Electrolyte Solution for Secondary Lithium Battery

Addition of a small amount of fluoroether to propylene carbonate containing solvents increased first coulombic efficiencies of graphite electrodes having relatively large amounts of mesopores with diameters of 1.5-2 and 2-3 nm at 25℃ while the effect of fluoroethers was low at -10℃ probably because of the low reaction rate for surface film formation on graphite
