The sensitivity of Li-ion battery materials to moisture complicates their synthesis, storage, processing and recycling. Here, authors show that protonation causes structural instability in LiNixCoyMn1-x-yO2 (0 <x,y < 1) and that controlled H+ and Li+ concentration in aqueous processing is critical.
