- The dynamic growth of mobile technologies is a driving need for portable power sources. The most popular division of electrochemical cells relies on the type of chemical reaction within the cell. Current data coming from the Polish market show that despite the growth in the sale of secondary power sources, zinc-carbon and alkaline batteries are still the most popular. The results of non-reductive acidic leaching of zinc and manganese from the waste batteries stream have been presented. Manganese was leached with almost 100% yield in an experiment with a solid to liquid ratio equal to 4/1, pH of 1.04, and H2SO4 concentration of 72.5 wt. %. High yields were also obtained for zinc recovery from the waste stream (100% for two series with solid to liquid ratio 4/5, pH of 0.80; H2SO4concentration of 37.2 wt. %, and solid to liquid ratio 1/2; pH of 1.01; H2SO4 concentration of 27.3 wt. %). Besides, the quantitative and qualitative analysis of Zn-C and Zn-Mn batteries introduced to the Polish market and waste generated in the years 2010-2018 has been presented.
