In an aspect, a negative active material for a rechargeable lithium battery that includes a silicon-based active material including a core including carbon and SiOparticles (0.5&#x2266;x&#x2266;1.5); and a coating layer surrounding the core, and a negative electrode and a rechargeable lithium battery including the same are provided.

Negative active material for rechargeable lithium battery, and negative electrode and rechargeable lithium battery including same

Disclosed is a method of preparing a negative electrode for a rechargeable lithium battery. The steps include vacuum-drying a negative electrode precursor, the negative electrode precursor comprising a negative active material and an aqueous binder. The steps may further include vacuum-drying a lithium cell battery that includes a vacuum-dried negative electrode.

Method of fabricating an anode and a lithium battery

A non-aqueous electrolyte for a lithium secondary battery is provided. The electrolyte comprises a lithium salt, a non-aqueous solvent, and an organic compound selected from the group consisting of compounds represented by Formulae (1) to (6): wherein Rto Rare each independently selected from the group consisting of primary, secondary, and tertiary alkyl groups, alkenyl groups, and aryl groups; X is hydrogen or halogen; and n and m are numerical values ranging from 0 to 3.

Electrolyte for lithium secondary battery and lithium secondary battery comprising same

A sealed battery includes a can for receiving an electric generator, a sealing member crimped on an opening of the can and connected to one of a positive electrode and a negative electrode of the electric generator, a gasket disposed between the can and the sealing member, a cover cap disposed on the sealing member with an insulating member disposed between the cover cap and the sealing member, a current control member disposed between the cover cap and the sealing member to cut-off a flow of current when a temperature of the battery is increased above an allowable level, and a shock absorber disposed between the cover cap and the current control member to prevent shock from being directly transmitted to the current control member.
