Abstract:
Provided are a nonaqueous electrolyte for improving overcharge safety and a lithium battery using the same. The nonaqueous electrolyte according to the present invention forms a polymer due to its oxidative decomposition even if there is an increase in voltage due to overcharge of a battery by some uncontrollable conditions, so that overcharge current is continuously consumed, thereby protecting the battery. Therefore, overcharge safety of the battery can be enhanced, and occurrence of swelling is reduced. Also, deterioration in formation, standard capacity and cycle life characteristics can be prevented.
Abstract:
Disclosed is related to a printing device for performing a multi-color gravure offset printing operation in one rotation of a gravure offset roll for various shapes of printing material, and a method therefor.
