The discharge capacity of zinc-carbon cells (Leclanche cell) is limited by the performance of the cathode material (MnO 2 ) and physical properties of carbon powder added to MnO 2 . Acetylene black, Vulcan XC 72, Black Pearls 2000, and a carbon composite (consisting of 50% acetylene black and 50% Black Pearls 2000®) were evaluated as cathode additives in test cells and were compared. The study indicated that cathode mixture with Black Pearls 2000®showed improvement in performance than acetylene black, the most commonly used carbon in commercial zinc-carbon cells. The performance of the test cells was found to have a correlation with the physical properties of the carbons used.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
