摘要:
The present invention relates to a nonaqueous electrolyte for a battery, and more particularly to a novel nonaqueous electrolyte for a battery in which a furanone based derivative is added to a conventional nonaqueous electrolyte for the lithium battery to inhibit decomposition of the electrolyte, and thereby the rate of increase of the battery thickness when it is allowed to stand at a high temperature is significantly decreased and capacity storage characteristics at high temperature are improved.
摘要:
A non-aqueous electrolyte for a lithium secondary battery includes a lithium salt, a basic organic solvent including a carbonate-based solvent, and a halogenated diphenyl ether compound represented by Formula 1: wherein Y is —O— or —R1—OR2—, where R1 and R2 are the same or different, and R1 and R2 are a C1-C5 alkyl group, an alkenyl group, or an alkoxy group, and only one of the phenyl rings is substituted with a halogen X1, where n is equal to 1, 2, 3, or 4 and the halogens in di-, tri-, and tetra-halogen substitutions are the same or different.
摘要:
A cathode for lithium secondary batteries coated with a slurry including an active material, a binder and a solvent, and further including a polymerization inhibitor, is disclosed. Gelation of the slurry is prevented during production of the cathode so that adhesion of the slurry is enhanced, thus achieving improved coating properties of the cathode and facilitating the coating of the slurry.
