。[Detailed description of the invention] The present invention is an improvement 1c of electrode plates for lead-acid batteries.
In particular, the purpose is to improve the cycle life of repeated charging and discharging due to the difference in discharge characteristics ζζ by improving the active material.

で参つ良。In general, paste-type electrode plates are made by adding dilute sulfuric acid to a lead compound and making a paste-like active material, which is then placed on a substrate such as a cast grid or expanded metal and then dried.The process is also simple. Although the discharge characteristics are good, there is a problem that the active material falls off the electrode plate when charging and discharging at a relatively deep level, and the charge/discharge cycle life is reduced by 8 times. When a compound is used as a haze material, polytetrafluoropenalene is used as a binder for active material particles, but the amount added is 0.01 to 1.
Therefore, the active material particles and specific surface area increase, and the above addition amount cannot bind the lead oxide particles. 1. They fall off by repeated charging and discharging. However, it is not possible to improve the cycle life.

ことを特徴とするものである。As a result of extensive research aimed at improving these drawbacks, the present invention has resulted in the discovery of an electrode plate for lead-acid batteries that can improve discharge characteristics and knife-through life due to repeated charging and discharging. That is, the present invention provides a lead-acid battery monthly electrode plate in which a paste-like active material is applied to a lead-acid battery substrate, in which polytetrafluoroethylene powder of 0.10 to 10.0% is used as the active material. It is characterized by being made of fine lead oxide having an average particle size of 0.1μ or less.

。In the present invention, the amount of polytetrafluoroethylene added in i is 0.1 to 10. HAth @ specified in Ovtll is 6.
If it is less than 1 vt-, it will not be possible to bind the lead oxide fine powder and prevent the lead oxide active material from falling off, and if it exceeds 10.0"-, the lead oxide fine powder will not be able to bind. This is because the amount decreases and the activation as a storage battery decreases.
