Abstract
The topotactic insertion of Li+ in λ-MnO2 involved an evolution of oxygen and a reduction of Mn(lV) to Mn(III) in a (LiCl + LiOH) solution. The major reaction could be represented as λ-MnO2 + xLiOH → LixMnO2 + (x/2)H2O + (x/4)O2, where x denotes moles of inserted Li+ per mole of λ-MnO2. The extraction of the inserted Li+ was studied by using a solution containing either an acid(HCl) or an oxidizing agent(Br2, K2S2O8).Keywords
