Abstract

PURPOSE:To minimize the variation in the life of a cathode plate for a lead storage battery by immersing a plate packed with an active material in a diluted sulfuric acid solution containing a tin salt or a tin compound. CONSTITUTION:After a substrate for a cathode electrode is made from a tin-free lead-calcium alloy, an active material such as lead powder is packed into the substrate and then the thus obtained plate is immersed in a diluted sulfuric acid solution containing a tin salt or a tin compound. While the plate is not immersed in the diluted sulfuric acid solution, the amount of the tin salt or the tin compound contained in the solution is maintained constant. During immersion of the plate in the solution, immersion conditions such as the time of immersion, the temperature of immersion, the concentration of sulfuric acid in the solution and the amount of the tin salt or the tin compound in the solution are maintained constant.

Description

用いているものがある。Conventional technology Conventionally, so-called maintenance-free batteries use a base made of a lead-calcium alloy as electrode plates, but if a deep discharge cycle or deep discharge is performed, a passive state forms at the contact interface between the base and the active material. In order to eliminate such a drawback that a layer is formed and the capacity deteriorates early, some devices add tin to the base alloy and use a base made of a lead-calcium-tin alloy.

化する。Problems to be Solved by the Invention Prior to manufacturing a base made of lead-calcium-tin, it is necessary to melt each of lead, calcium, and tin to create an alloy hot water. In this case, since tin has a lower specific gravity than lead, it floats to the top of the alloy bath, and the amount of tin in the alloy bath tends to decrease over time due to oxidation and evaporation. For this reason, the tin content in substrates produced using the alloy molten metal varies greatly. On the other hand, in the case of lead-calcium alloy substrates, as a measure to prevent early deterioration of battery capacity due to deep discharge cycles or deep discharge leaving, it is common to add approximately 1% tin, and as the tin content decreases , battery capacity deteriorates early.

従って、従来法によって製造される基体中の錫含有量の
バラツキは電池寿命を大きくばらつかせ、品質低下をき
たす等の欠点を有している。Therefore, variations in tin content in substrates produced by conventional methods have disadvantages such as greatly varying battery life and deteriorating quality.

填した後肢極板を錫塩あるいは錫化合物の存在する希硫
酸に浸漬するようにしたものである。Means for Solving the Problems: An anode base made of a lead-calcium alloy is manufactured without adding tin to the alloy, and the base is filled with an active material such as lead powder and the hind limb electrode plate is treated with tin salt or tin. It is designed to be immersed in dilute sulfuric acid containing a compound.

作用 希硫酸中に存在する錫塩あるいは錫化合物の量は、極板
を浸漬しない間は減少することなく塩ちるいは錫化合物
の量等の浸漬条件を一定に保てば、極板中の錫塩あるい
は錫化合物の存在量はほぼ一定になる。Effect The amount of tin salt or tin compound present in dilute sulfuric acid does not decrease while the electrode plate is not immersed.If the immersion conditions such as the amount of salt salt or tin compound are kept constant, the amount of tin salt or tin compound in the electrode plate will decrease. The amount of tin salt or tin compound present becomes approximately constant.

て従来の方法で化成し陽極板を得た。Example First, a solution for dipping an anode plate was prepared by adding 101 parts of tin per ti of dilute sulfuric acid having a specific gravity of 1.05. Next, an anode plate, in which a base (3 m thick) made of a lead-calcium alloy was filled with an active material raw material such as lead powder, was immersed in the solution for 10 minutes. In this case, the anode plate was immersed while stirring the liquid. After dipping, it was dried and chemically formed using a conventional method to obtain an anode plate.
