Conductive cell frame

Abstract

A conductive cell frame for connecting a plurality of battery cells is disclosed. The conductive cell frame includes a first conductive portion and a plurality of second conductive portions, and the upper surface of each second conductive portion is connected to the first conductive portion through a eutectic portion. The lower surface of each second conductive portion is provided with at least one protruding welding portion, wherein the second conductive portion is connected to the housing of the battery cell through the protruding welding portion. The first conductive portion and the second conductive portion are made of different materials, wherein the resistance of the second conductive portion is greater than the resistance of the first conductive portion. Thus, a small current can be used to connect to the conductive cell frame and the battery cell, which not only reduces the consumption of energy, but also avoids damage of the battery cell during the electric welding process
