摘要： PURPOSE:To improve the utilization factor of a paste electrode plate by charging active material paste into a porous metallic substrate having three- dimensional continuous cavities, and then, performing preliminary compression with a press, and making it into the final thickness by a roll press. CONSTITUTION:A band-shaped wide foaming nickel substrate fixed in thickness, which has cavities continuous in three dimensions, is prepared, and it is charged with active material paste, which has nickel hydroxide for its main ingredient, to manufacture an electrode plate. This electrode plate is preliminarily pressed at 0.1-1t/cm by a plate press, and then, it is compressed into the specified thickness of an electrode plate by a roll press. Hereby, an electrode plate in which excessive elongation and the wire breaking of a board are prevented and besides which is compressed enough into high charge density can be obtained. Moreover, the area of contact between the active materials and to the conductive agent increases, and the strength increases, and the utilization factor and quick discharge performance can be improved.

摘要： PROBLEM TO BE SOLVED: To charge a storage battery at high precision, so as to prevent overcharge, by controlling charging through a process of detecting that the change amount of the inner impedance per unit time in the charging last stage of the storage battery exceeds a specified value. SOLUTION: The inner impedance of a storage battery, the battery voltage, the battery temperature are changed around 140 minutes after charge is started, in particular, the inner impedance is suddenly changed. The change amount of the inner impedance per unit time is approximately half as large as the inner impedance in 140 minutes and larger than that of the battery voltage and the battery temperature. Therefore, control of charge by the detection of the change amount of the inner impedance per unit time is more reliable than that by the detection of the charge of the battery voltage and the battery temperature, the risk of overcharge is low, and charge can be controlled at high precision. When the change amount of the inner impedance exceeds 2.0MΩ/min., that is detected, charging is stopped, and the charging electric amount is 95% of the discharging amount, and overcharge can be prevented.

摘要： PURPOSE:To enlarge the surface areas, increase the discharging characteristic, and prolong the lifetime of battery by forming a metal electrode from a group of metal particles having a number of minute gaps for flowing-through of the electrolytic solution, and accommodating it in a conductive porous vessel. CONSTITUTION:A metal electrode 3 is formed from a group of metal particles 3a having a number of minute gaps 3b, which serve for flowing-through of the electrolytic solution, and this is accommodated in a conductive porous vessel 4. Therein the surface areas contacting the electrolytic solution can be increased compared with a metal electrode consisting of an ordinary plate, which enhances the discharging characteristic accordingly. Because this group of metal particles 3a is accommodated in porous vessel 4, eventually generated corrosions on them remain within the porous vessel 4, and they serve the reactions to the last stage to achieve long lifetime of the battery. This permits increase in the contacting areas of the metal electrode 3 with the electrolytic solution and enhances the discharging characteristics accordingly, and thus the battery life can be prolonged.

摘要： PURPOSE:To enhance the hydrophilic property of a separator without deteriorating the chemical stability of that, by using a separator made of a polyvinyl alcohol film, and an electrolyte which contains a glycol. CONSTITUTION:An alkaline battery includes a separator made of a polyvinyl alcohol (PVA) film, and an electrolyte which contains a glycol. The PVA film having a thickness of 20-75mu is prepared from an aqueous PVA solution having a polymerization degree of 1,000-2,500 (preferably 1,500-2,000), and a saponification degree of over 95 (preferably over 97) mol%. After that, the PVA film is subjected to any one of the following treatments: it is converted into an acetal; it undergoes a bridge-formation treatment through radiation exposure; it undergoes the reaction with boric acid, borax or the like and is converted into a gel; it undergoes a heat treatment in a gaseous phase or an aqueous phase to make its crystallization degree to be increased to 0.3-0.6. A polyethylene glycol, tetraethylene glycol or triethylene glycol is preferred as the former glycol, because it is soluble in water and has resistances to both alkali and acid.
