Abstract

PURPOSE:To lengthen the cycle of charging and discharge, by providing a positive electrode plate made of a lead alloy core containing no antimory a negative electrode plate made of a lead alloy containing no antimony, and an electrolyte in gel. CONSTITUTION:A clad positive electrode plate comprises a metal core 1 made of such a lead alloy containing substantially no antimony as a lead-calcium-tin- aluminum alloy and a lead-antimony-arsenic-tin-sulfur alloy whose antimony content is 1% or less, a tube 2, a negative electrode active material 3, etc. A positive electrode plate 6 is a grate made of such a lead alloy containing substantially no antimony as a lead-calcium-aluminum alloy. An electrolyte 9 in gel comprises silica and diluted sulfuric acid. The hydrogen overvoltage of the negative electrode plate 6 does not fall due to a contamination with antimony. The metal core 1 is surrounded by the active material 3 and tightly held by the tube 2. This results in lengthening the cycle of charging and discharge.

【発明の詳細な説明】 産業上の利用分野 本発明は無保守！Ｏ蓄電池の改良、特にクラッド式無保
守鉛蓄電池に関するものである。[Detailed description of the invention] Industrial application field The present invention is maintenance-free! This invention relates to improvements in O-acid batteries, particularly clad type non-maintenance lead-acid batteries.

充放電サイクル寿命が短いという問題点があった。Conventional technology and its problems The most common method for maintenance-free lead-acid batteries is to use a lead alloy that does not substantially contain antimony, such as a lead-calcium alloy, in the lattice, and a paste-type electrode plate is used as the positive electrode plate. It was applied. However, the common drawbacks of lead alloys that do not contain antimony are that they tend to selectively corrode between grains, and that they elongate significantly, causing the active material to soften and fall off.
There was a problem that the charge/discharge cycle life was short.

である。Sixth Means for Solving the Problems The present invention provides a clad positive electrode plate using a lead alloy core metal substantially free of antimony, and a negative electrode plate using a lead alloy lattice substantially free of antimony. It is characterized in that it is laminated to form a group of electrode plates through a highly porous separator made of acid-resistant aim, and that the electrolyte is in a gel state.

液を保持しているので、活物質の脱落防止。Function: In the lead-acid battery according to the present invention, there is no drop in the hydrogen overvoltage of the negative electrode plate due to antimony contamination, and self-discharge is small. In addition, since a clad type electrode plate is used as the positive electrode plate, the core metal is surrounded by the active material and tightly held by the tube, so there is no performance deterioration during charging and discharging, and the battery life is long. In addition, the electrolyte is gel-like, so not only is there no risk of leakage, but there is also less liquid loss due to the sealed reaction of the oxygen cycle. Furthermore, a highly porous lever is interposed between the positive and negative electrode plates to hold the gel electrolyte, preventing the active material from falling off.

なことがあっても活物質脱落のおそれが少ない。In addition to the functions, a thin tube with low resistance can be used for the positive electrode plate, improving discharge performance. Furthermore, even if both ends of the tube become detached from the joint due to elongation of the core metal, there is little risk of the active material falling off.
