METAL PLATE AS ELECTRICAL CONNECTING MEMBER AND BATTERY PACK PREPARED USING THE SAME

摘要

A metal plate is provided to prevent a short circuit of a battery cell by forming unevenness on a connection part to inhibit fluidity of a molten solder paste, and have a special structure capable of producing various core packs. A metal plate(300) is a member for electrically linking many batteries to one another and further connecting a protection circuit module to the joint. The metal plate includes a plate main body(310) for welding with an electrode terminal, and a connection part(320) which is outwardly protruded from the main body to solder the protection circuit module. A micro unevenness(320a) is formed on the surface of the connection part to suppress fluidity of a molten solder paste.
