PURPOSE:To improve the charging performance of a leakage-less closed type battery by putting a piece of paper made of carbon fiber in contact with the surface of electrode plates made of an active material mixed with short carbon fiber so as to assemble them together with a mat body impregnated with an electrolyte. CONSTITUTION:Short carbon fiber of 0.3% against the paste weight is added to the paste for a positive electrode and a negative electrode, then they are kenaded and filled into substrates, and after aging, formation, washing and drying, a positive electrode plate 2 and a negative electrode plate 3 are formed. Paper- like carbon fiber 1 of 0.3mm. with a weight of 15gr/cm<3> is put in contact with the surface, and they are assembled together with mat-like glass fiber 4 impregnated with an electrolyte to form a leakage-less closed type lead battery. Therefore, an internal resistance can be reduced due to the short carbon fiber added in the paste and the paper-like carbon fiber put in contact with the surface of electrode plates, thereby the charging performance can be remarkably improved. |
