This article in our series on producing lead-acid batteries explores the manufacture of lead oxide using the ball mill, or Shimadzu process. Technical editor Dr Mike McDonagh looks at the technology and the factors that will determine the quality of the end product and ultimately the optimal performance of the lead-acid battery.
The heart of a lead-acid battery is its active material. If this is not manufactured properly and accurately, the battery performance, or life, will be irretrievably compromised. As with all the other chemical processes in the manufacturing sequence, once completed, it is practically irreversible. The . . .
