PURPOSE:To increase the energy density of the pasted negative plate of an alkaline storage battery and enable rapid charging of the battery by packing a given woven carbon fiber cloth or similar material with a paste prepared by mixing a powder mixture of cadmium oxide and the like with a solvent such as ethylene glycol and an ionic macromolecular compound. CONSTITUTION:A powdery mixture of cadmium oxide, metallic cadmium, nickel, etc. is mixed with a solvent such as ethylene glycol or isopropyl alcohol and at least one ionic macromolecular compound soluble in this solvent to prepare a paste. Next, after a woven or nonwoven cloth of carbon fibers with diameter of 4-100mu is immersed in the paste and continuously passed through it, the impregnated cloth is partially dried in a dryer maintained at a given temperature. Following that, the thickness of the partially dried cloth is adjusted to a given level and then a hot air dryer is used to remove the solvent such as ethylene glycol prior to cutting the cloth into given dimensions. |
