摘要： PURPOSE:To remarkably improve the life performance of a sealed lead acid battery for use in cycle service in which charge and discharge are repeated irregularly. CONSTITUTION:In a sealed lead acid battery for use in cycle service, the amount of electricity with which the battery is charged after a discharge is equal to the sum of the amount of electricity discharged and a certain amount of electricity. The latter amount of electricity is 5-10% of rated capacity during use at room temperature.

摘要： PURPOSE:To restrict accumulation of sulfate and to improve life performance by adding carbon of no less than 0.5wt.% and no more than 5.0wt.% in terms of mass to a negative electrode active material. CONSTITUTION:Carbon is added to a negative electrode active material by no less than 0.5wt.% and no more than 5.0wt.% of the mass of the negative electrode active material. The carbon has specific surface of no less than 30m /g. Accumulation of sulfate in a negative electrode plate is reduced, while degradation of a positive electrode plate caused by extension of a positive electrode lattice is eliminated in the side of a positive electrode. The capacity is not reduced as long as the amount of carbon to be added is defined as above, and reduction in the strength of the active material is prevented. There is no possibility of the active material causing falling off, which leads to early reduction in the capacity due to shortcircuit, thus improving the life performance.

摘要： PURPOSE:To intend a longer cycle life by using a grid made of lead alloy composition including specified-amount antimony for a positive electrode and including specified-amount phosphoric acid in electrolyte. CONSTITUTION:If a grid made of lead alloy composition including 0.5-2.5wt% antimony is used for a positive electrode plate, 0.1-5.0wt% phosphoric acid is included in electrolyte and Pb-Sb group alloy is used for the positive electrode grid, there is no deterioration of positive electrode active material, but antimony ions are solved out of the grid into electrolyte and deposited to degrade battery performance. If case of a battery with gelled electrolyte, less deposition of antimony to a negative electrode plate is allowed, compared with a retainer type. Especially, if phosphoric acid is included in electrolyte, gel is hardly broken and syneresis liquid is reduced, resulting in greatly less deposition of antimony to the negative electrode plate.

摘要： PURPOSE:To prevent shortcircuiting resulting from slipping-off of active substance and prolong the lifetime by making a separator with a recess approx. in the same shape as an electrode plate provided in a solution retaining sheet, and fitting the electrode plate in this recess in the separator. CONSTITUTION:A bipolar battery according to the present invention includes a separator sheet 4 having liquid retaining property, which is made of fine glass fibers or fine synthetic fibers or mixture thereof produced through paper making process, and in this sheet a recess is formed in approx. the same shape as electrode plate. Electrode plates 1 and 3 are fitted in this recess from both sides. The surface of electrode plate is pressurized, and active substance having softened and slipped off stagnates in the recess, not reaching the mating electrode plate, and thereby shortcircuiting is prevented. Use of this type of sheet can also increase the electrolyte holding amount to lead to prolongation of the lifetime.

摘要： PURPOSE:To increase discharge capacity and cycle life by specifying the amount of PbSO4 existing in the positive active material of a clad type positive plate before formation. CONSTITUTION:In a gel type sealed lead-acid battery in which a non-formed clad type plate is used as the positive plate, then formation is conducted within a container, the ratio of PbSO4 in the non-formed positive plate is specified to 20% or less to increase discharge capacity and cycle life. Discharge test was conducted with samples in which the amount of PbSO4 was varied. Batteries B and C containing 5% and 10% PbSO4 in their positive plates before formation showed high performance. Batteries having smaller PbSO4 content in their positive plates before formation showed longer life. This means that less stratification of an electrolyte gives uniform charge-discharge to positive and negative active materials.

摘要： PURPOSE:To accurately determine residual capacity by measuring it from capacitance data of a battery. CONSTITUTION:Capacitance of a battery is measured by using a power source having a frequency of 1HZ or more, and the residual capacity of the sealed lead-acid battery is determined by this capacitance value. The relation between the residual capacity and the capacitance is linear as shown in the figure. C' = capacitance X number of cells/nominal capacity is found, then the relation between C' and residual capacity is found from the next equation. residual capacity (%) = 2000C'/3-100/3.

摘要： PURPOSE:To obtain a sealed clad type lead battery with excellent discharging capacity and cycle lifetime by installing a group of electrode plates composed of specified separators, positive and negative plates into an electrolytic cell with pressure more than a specified value under the state of being dry before putting electrolyte into the electrolytic cell. CONSTITUTION:Glass fiber formed into sheet with uniform fiber diameter of less than 10mum is used for a separator 3 and gelled dilute sulfuric acid for electrolyte. A group of electrode plates composed of separators, positive and negative plates 2 with pressure more than 20kg/dm per apparent surface are (longitudinal and transverse dimensions of a plate) of the positive plate is accommodated in an electrolytic cell under the state of being dry before putting electrolyte into the electrolytic cell. The glass separator 3 extremely increase its surface contacting with the positive plate 1 by strong pressing and has the construction in which the separator easily absorbs H2SO4 formed at charging. Thus, the gap of the clad type positive plate and the separator becomes about half compared with a conventional battery not being pressed. Therefore, discharging capacity and cycle lifetime are extremely improved.
