Abstract:
A nonaqueous electrolytic solution and a lithium battery employing the same include a lithium salt, an organic solvent, and a halogenated benzene compound. The use of the nonaqueous electrolytic solution causes formation of a polymer by oxidative decomposition of the electrolytic solution even if a sharp voltage increase occurs due to overcharging of the battery, leading to consumption of an overcharge current, thus protecting the battery.
Abstract:
An the electric energy storage device includes a cylindrical rolling up electrode body, a cathode lead connecting plate, an anode lead connecting plate, a terminal plate, and a container. The rolling up electrode body includes a cathode and an anode leads formed by cathode and anode collectors. The cathode and anode leads are separately extended from one side of the rolling up electrode body. The terminal plate includes a cathode lead connecting plate, an anode lead connecting plate and an insulation combing member for integrally combining the cathode lead connecting plate with the anode lead connecting plate. The container receives the rolling up electrode body. The electric energy storage device may be advantageously connected to another electric energy storage device in serial or parallel. Additionally, the electric energy storage device has some advantages such as reduced volume, enhanced convenience, improved productivity, etc.

Abstract:
A lithium ion secondary battery is provided. The lithium ion secondary battery generally comprises an electrode assembly, a container for accommodating the electrode assembly; and an electrolyte. The electrode assembly comprises two electrodes having opposite polarities and a separator. The separator comprises a porous membrane comprising clusters of ceramic particles. The porous membrane is formed by bonding the particle clusters with a binder. Each particle cluster is formed either by sintering or by dissolving and re-crystallizing all or a portion of the ceramic particles. The ceramic particles comprise a ceramic material having a band gap. Each particle cluster may have the shape of a grape bunch or a lamina, and may be formed by laminating scale or flake shaped ceramic particles.
