Zinc corrosion is an unavoidable phenomenon in alkaline systems. Additives like surfactants and metals at the ppm level are typically included in the zinc-alkaline cell production process to help suppress corrosion. Though these inclusions have helped remediate the issue, the inclusions themselves bring forward new issues such as increased toxicity and cost. Therefore, a method for achieving reduced Zn corrosion that can either complement or replace additives is highly desirable. In this work, a method for the scalable improvement of zinc microparticle crystallinity, without the use of additives, is presented and detailed. The recrystallization process involves oxide film formation, thermal annealing, and oxide film removal. The process converts polycrystalline particles into either a single crystal or one with larger, fewer total grains while conserving particle shape and size. This paper demonstrates reduced corrosion and enhanced achievable capacity for the recrystallized particles as well as improved cyclability. More specifically, the recrystallized particles demonstrate a 19% reduction in corrosion current and a 12% increase in achievable capacity when probed by linear sweep voltammetry and constant current discharge, respectively. When cycled in charge-discharge experiments, the recrystallized particles boast up to a 114% improvement in cyclability.
