The present invention relates to a battery temperature adjusting system including: a battery unit having a heating pad; a leading wire connected to the battery unit; and a current induction unit surrounding the leading wire, wherein the current induction unit is electrically connected to the heating pad. The battery temperature adjusting system according to the present invention generates the induced current by applying the current induction unit surrounding the leading wire connected to the battery unit, and increases the temperature of the battery unit by supplying the induced current to the heating pad, thereby obtaining a desired battery output in a low-temperature region even without the use of an external power source.

Battery temperature adjusting system and operating method thereof

Provided are a secondary battery, a battery module, and a battery pack, which have improved safety. Particularly, since a bulletproof material is disposed on the inside and/or the outside of an exterior part, even when a conductive needle-shaped member penetrates a secondary battery, heating, burning, discharge of evaporated electrolyte, and electrical contact between the needle-shaped member and an electrode can be prevented, thereby improving safety of the secondary battery, the battery module, and the battery pack.

Secondary battery having improved safety

A lithium ion secondary battery including a compound containing at least one thiol group (&#x2014;SH) in a molecule in a unit cell of the battery is provided. By including the compound containing thiol group (&#x2014;SH) having good reactivity with copper or copper ions, the formation of dendrite through the reduction of copper ions present in the inner portion of the battery or produced during operating the battery at the surface of an anode may be prevented. The internal short between two electrodes due to the dendrite may be also prevented.

Lithium ion secondary battery without internal short

Provided are a method of preparing an electrode assembly, in which both sides of a single current collector are coated to form an anode and a cathode, and the current collector is then bent into a vertical sectional zigzag shape and integrated in a state of disposing a separator at interfaces between facing electrode patterns, an electrode assembly prepared by the above method, and a secondary battery comprising the electrode assembly.

Method of preparing electrode assembly and electrode assembly prepared using the method

Provided is a novel structural electric device having improved safety. More particularly, provided is a novel structural electric device devised to resolve several issues regarding heat generation, ignition, and explosion, which may be caused by a sharp needle-shaped object penetrating an electric device.

Structural electric device having improved safety

Provided are an electrode lead of a secondary battery where a protection layer for anti-corrosion is selectively formed at an electrode lead portion at the cell outside and a secondary battery including the same. Since a protection layer for anti-corrosion is selectively formed only on an electrode lead portion at the cell outside, the corrosion of the electrode lead may be prevented from an external environment and the resistance of a cell may be reduced simultaneously.

Electrode lead comprising protection layer for anti-corrosion and secondary battery comprising the same
