Abstract
The utility model relates to a weldable MWT battery assembly, comprising a plurality of battery strings. The battery strings comprise a plurality of batteries which are connected in series in a transverse direction. The battery comprises a substrate (1). A positive electrode on the front surface of the substrate (1) is led to the back surface of the substrate through a hole, so as to form an emitting electrode (2). A lateral insulating band (4) is covered outside a lateral row of the emitting electrode (2). A vertical insulating band (5) is connected between the lateral insulating bands (4) on the outer side of the left-most side or the right-most side of emitting electrode (2). The back electrodes (3) on a lateral row are connected by back electrode solder strips (6). The plurality of back electrode solder strips (6) of each battery extend horizontally and are connected with vertical solder strips (8) of an adjacent battery. The weldable MWT battery assembly is advantaged by convenient welding and simple operation, and can be directly applied in large scale production.
