Abstract
A zinc alkaline secondary battery includes a positive electrode, a negative electrode including a multi-valent oxide species, a separator system disposed between the electrodes, and an alkaline electrolyte in contact with the negative electrode. The alkaline electrolyte includes hexametaphosphate salt and zinc acetate. Ligands from the hexametaphosphate salt and zinc acetate are anchored to the negative electrode via chelation sites created by the multi-valent oxide species.
