Abstract
The ITE organic polymer activators for extending the life of lead-acid batteries were first developed by a Japanese group in 1997 led by Dr. Akiya Kozawa. The initial activator was a composite mixture of carbon and polyvinyl alcohol. A US Patent (5,958,623) was issued on September 28, 1999 for this new lead-acid battery activator. Later research found that the organic polymer alone was very effective which started a wide search for other such organic additives. The most effective one to date is an acrylic polymer with a high molecular weight. This paper summarizes the current results involving this acrylic polymer.
