Abstract

The invention relates to a battery (100) comprising: a battery plate (112); a first-ordered solder plate (102) attached to one or more concentric coils of the first electrode (118) of the cathode or anode forming part of the battery core of the battery (100), in which the first-ordered solder plate (102) comprises: a first-ordered conductive surface (104) in contact with one or more concentric coils of the first electrode (118); two or more first-ordered conductive paths configured to allow at least one of the entry of first material into the battery core of the battery (100) or the exit of second material from the battery core; The difference is that these paths are alternating paths with approximately equal areas, and the ear (110) is welded to the battery cover (112), the ear (110) is positioned on one of these paths.
