General Description of the Research Project Secondary batteries, such as lithium-ion batteries, are expected to significantly change the energy environment for the next generation. Zinc-air batteries are capable of storing five times more energy than lithium-ion batteries. Thailand is a zinc-producing country, and zinc-based batteries are attracting a lot of attention. As a stationary secondary battery e.g. zinc-air batteries show a very low cost per Wh. In this study, we aim to construct a catalyst system to improve the current density and to create a zinc-based battery for practical use. The current density for the target implementation in this study is about 60 mA cm-2. This work will provide a practical catalyst and demonstrate its practicality by using it to assemble a zinc-air based battery and zinc flow battery module in practice. In particular, the practical application of installed zinc-based secondary batteries could contribute to power leveling, make energy cleaner, and lead to technological innovation using domestic minerals.
