A battery module that can be charged and discharged with a large current. One of the methods of serially connecting or connecting batteries is to use a connecting guide to bridge between the electrodes of adjacent batteries, and to connect the connecting guides to form a current loop with the batteries by soldering. , .S, [0003] Referring to the eighth figure, it is a perspective view and a schematic diagram of a conventional battery connection guide. Generally, the material of the battery 200 casing (including the electrode portion) is usually pure nickel, iron-plated nickel or aluminum, and is mainly used to prevent the active material inside the battery 200 from directly contacting the outside; if it is directly used, it is the same as the battery 2 casing. The material battery connection guide i 〇〇 has the advantage that the electrode 21 () is easy to solder with the connection guide 100, but since the above material has poor conductivity, it is not suitable for a battery module for charging and discharging a large current. [0004] The battery connection guide 1 commonly used in a large current charge and discharge battery module is a copper material because the conductivity of the copper material itself is good; since a large current is required to be supplied when the battery module is charged and discharged, The thickness of the copper connection guide must be increased to further enhance its electrical conductivity, and the increase in thickness correspondingly increases the difficulty in soldering between the battery and the connection guide 1GG. The main reason is that when the thickness of the connection guide 4100 is increased, 09911204 is soldered! Form No. A0101 Page 3 of 20 0992021347-0 201138185 [0005] [0006] The required current needs to be relative to this process. The stress at the weld is also required to be larger, such as the temperature increase due to the _ degree, and the welding quality required for welding; the accumulation of heat causes the heat to be difficult to concentrate, and in addition, due to the copper itself, copper can be quickly fascinated _ = good thermal conductivity 'so in the welding caused by the heat is not easy 隼 / the heat of its surface' is therefore a problem in the welding process, improve the difficulty of welding. "This, how to provide ~ Battery 200 connected to the electricity 7: good electrical conductivity, thermal conductivity and easy to work with the power pack, for the current industry of the witch blade 100 in the high current charge and discharge battery model one to overcome and improve the problem.
