Description
Guoli Zhang and seven colleagues add a surfactant to manganese dioxide cathodes to favor two-electron reactions in aqueous zinc batteries, in a study from twenty twenty-six. A two-electron transfer doubles the capacity a cathode can hold in theory, compared with one electron. In mildly acidic zinc batteries, proton supply limits that reaction. Loss of material over time further hurts long-term stability.
The surfactant is sodium dodecyl benzene sulfonate. It stops the grains from clumping as they form. It also strengthens the pull on cations in the system. Extra proton uptake then aids the two-electron dissolution step on discharge. Manganese ions are drawn back and redeposit on charge. The cathode gave high capacity and kept eighty-four percent of it over ten thousand cycles. High electrode loadings did well too, and a second surfactant backed the strategy.
