A battery module has an improved gas venting structure, and a battery pack including the same. Heat emission efficiency of a battery cell can be improved, and the outflow of sparks or embers can be blocked even when a thermal runaway of a battery cell occurs by forming a bracket formed at a position where mesh structures are alternately formed, at an inside a plate where mesh structures are formed.

Battery module having improved gas venting structure, and battery pack including same

A method for assembling a secondary battery cell module by using an assembling jig including a plurality of guide rods disposed on a jig plate includes: mounting a lower frame on the jig plate while the guide rods are inserted into a plurality of arranging through-holes of the lower frame; disposing a plurality of battery cells on the lower frame; mounting an upper frame on the battery cells while the guide rods are inserted into a plurality of arranging through-holes of the upper frame; fastening the upper frame and the lower frame together; and separating the assembling jig from the upper frame and the lower frame.

Secondary battery cell module and assembling method thereof

A battery module includes a battery cell stack constituted by a plurality of stacked pouch-shaped battery cells, a battery module housing configured to receive the battery cell stack, and a heat dissipation member coupled to a portion of the battery module housing, wherein the heat dissipation member has a through-hole formed in a heat dissipation plate disposed so as to face the battery cell stack and a sealing member is added to the through-hole, and a method of manufacturing the heat dissipation member. It is possible to effectively prevent thermal runaway of a battery cell that has caught fire while minimizing an increase in volume of the battery module.

Battery module including heat dissipation member and method of manufacturing the heat dissipation member

A battery pack includes a battery cell and a bus bar electrically connected to the battery cell, wherein the bus bar includes a rupture portion configured to melt due to electric resistance heat generated by overcurrent and thus to rupture, the rupture portion having a plurality of through-holes therein.

Battery pack

A method for recovering valuable metals contained in printed circuit boards of waste electronic machine, and more particularly, a method for liberating metal and plastic laminated in waste printed circuit boards uses an organic solvent and then separates and recovers the liberated metal components using an electrostatic separation process.
