Abstract
The invention relates to a battery tag, a battery base and a battery. The materials of the battery tag and the battery base are formed by fiber which is prepared from one or more than one of polyolefin substances and subjected to surface hydrophilic treatment. Because the materials of the battery tag and the battery base are formed in such a way that fiber which is solely prepared from one of polyolefin substances including polyethylene, polypropylene and the like or is prepared from the mixture of the polyolefin substances is subjected to surface hydrophilic treatment, the battery tag and the battery base can absorb alkaline, have the capability of preserving water, can resist alkaline and realize insulation, the problem of liquid injection difficulty is solved. In addition, the battery tag and the battery base can adsorb part of electrolyte to increase the liquid injection quantity of the battery by 0.05g to 0.2g and improve the performance of the battery. In the process of recycling the battery, the electrolyte which is adsorbed on the battery tag and the battery base can be released into a battery cell so that the service life of the battery can be prolonged by more than 40 weeks.
