題である。Conventional technology Traditionally, so-called lead powder containing lead oxide as the main component has been used as a raw material in the production of paste-type lead battery electrode plates, which was kneaded with dilute sulfuric acid to form a paste, which was then filled into a lattice. It is manufactured through post-ripening and chemical conversion processes. The major problems with this method are that the ripening and chemical conversion steps take a long time, and that the acid mist generated during the chemical conversion step degrades the environment.

放電容量の増大に寄与していると言われている。This is because there is almost no OH chemically bonded to the surface of the crystal. It is said that the function of this OH- is to improve the wettability of the pbo crystal to the solution and to facilitate the penetration of the solution into the western part of the micropores present on the crystal surface. In addition, OH- generated by dissociation of water
H, which is paired with pbo, is directly involved in the discharge reaction of pbo,
It is said that this contributes to an increase in discharge capacity.

From 500 to 500, the main materials are Pb and Q. The amount of thermal decomposition also depends on the treatment time. By forming the surface layer of the PbO crystal to be PBO, a lower oxide, lead sulfate is produced when it comes into contact with dilute sulfuric acid, which is an electrolytic solution. In the process of converting the lead sulfate generated on the surface of this pbo crystal into PbO through electrolytic oxidation,
The surface of the chemically synthesized i'bo crystal becomes electrochemically active.
