This relates to a structure that prevents this.

るなどの欠点があった。Conventional technology and its problems Clad type lead-acid batteries have a positive electrode active material housed in a tube and are kept in a compressed state, so they have excellent charge/discharge cycle life performance and are suitable for electric vehicles such as forklift trucks and stationary applications. It is widely used. The core metal alloy used in this clad type positive electrode plate has conventionally been made of a lead-antimony alloy. This alloy has high mechanical strength and good corrosion resistance, so it hardly stretches or deforms during use. However, when the core metal corrodes and antimony is eluted, it precipitates on the electrode plate and lowers the hydrogen overvoltage, thereby increasing self-discharge. For this reason, lead-calcium alloys have been developed to reduce self-discharge by substantially eliminating antimony from the mandrel. However, the mechanical strength of this alloy is relatively low, and the core can be deformed or stretched due to corrosion, and the lower end of the core is fixed with a lower joint, similar to the conventional clad positive electrode plate with a lead-antimony alloy grid. If this happens, the mandrel may bend due to elongation and break, or the broken mandrel may pierce the tube and protrude, causing an internal short circuit.

早期に心金１の変形や切損をきたす欠点を有していた。Therefore, as shown in FIG. 3, the lower end 1' of the mandrel 1 is inserted into the opening of the lower connecting seat 4, and a gap 5 is formed below the mandrel 1 to absorb the elongation. is proposed. However, in the case of such a conventional structure, if the hole diameter of the opening of the lower connecting seat 4 is too large than the core metal diameter,
In other words, if the gap is large, the active material 3 falls through the gap into the gap 5 of the lower carrier seat 4 and fills the gap, making it impossible to absorb the elongation of the mandrel 1'. On the other hand, if the gap between the opening of the lower carrying seat 4 and the core metal 1' is small, rot may form on the face of the core metal 1'. Since the diameter of the mandrel 1' is substantially increased by the first layer, the mandrel 1' cannot freely slide through the opening of the lower link 84, which also has the disadvantage of causing early deformation or breakage of the mandrel 1. had.

触面は大きなギャップを設ける必要がない。EXAMPLE The structure of a clad positive electrode plate according to the present invention will be explained based on one embodiment shown in FIG. 1 and another embodiment shown in FIG. 1 is a core made of a lead alloy that does not substantially contain antimony, such as lead-calcium or lead-calcium-tin, 1' is the lower end of the core, 2 is a tube made of glass woven cloth, etc.
3 is an active material mainly composed of lead dioxide, and 4 is a lower part made of acid-resistant and oxidation-resistant synthetic resin that serves as a stopper to fix the mandrel 1' and prevent the active material 3 from falling out of the tube. 5 is a two-digit gap below the opening of the connecting seat to absorb the elongation of the mandrel 1, and 6 is a sheath of acid- and oxidation-resistant synthetic resin integrally formed on the surface of the mandrel 1'. The sheath 6 is inserted through an opening in the lower carrying seat 4. Saya 6
The fitting condition between the sheath 6 and the lower connecting seat 4 is such that they slide due to the downward extension of the mandrel 1. When the sheath 6 and the lower connecting seat 4 are made of thermoplastic plastic such as polyethylene or polypropylene, the surface Since the sliding properties of the two are good, there is no need to provide a large gap between the two contact surfaces.

Since it is covered with thermoplastic plastic 6, it has good sliding properties with the opening of the lower carrier seat 4, and almost no gap is required between the mandrel 1' and the opening. Therefore, the active material in the duplex 2 does not fall to the bottom. In addition, since the surface of the core metal 1' is covered with plastic such as polyethylene, there is no fear of corrosion even if it comes into contact with dilute electrolyte, and unlike the conventional type, the diameter of the core metal 1' is thicker. 11 slides! ] There is no risk of harm.
