This article examines the ultraviolet (UV) spectra of supersaturated zincate solutions obtained as a result of the discharging of the nickel-zinc system during their aging. A disadvantage of the nickel-zinc storage battery is its relatively short service life due to the instability of the zinc electrode. This instability is caused by the tendency of the zincate solution to become supersaturated. The UV spectra of the supersaturated zincate solutions obtained in the silver-zinc and nickel-zinc systems show significant absorption at 240 nm and strong absorption at 280 nm. The strong absorption at 280 nm in the supersaturated zincate solutions corresponds to the weak absorption in the solution obtained by ordinary dissolution. It is suggested that the stability of supersaturated zincate solutions may be increased by the formation of additional bridging bonds, which link the individual molecules of their aggregates to form a three-dimensional structure.
