Stabilizing Layered Structure in Aqueous Electrolyte via Dynamic Water Intercalation/Deintercalation

Liang Xue et al.

Summary: This work investigates the structural degradation of layered cathode materials, using LiCoO2 as an example, in aqueous electrolytes. The research finds that the accelerated irreversible layered-to-spinel phase transition caused by H+ insertion is the main reason for the structural degradation and fast capacity fading in LiCoO2. To mitigate the influence of H+ and the adverse phase transition, a Li-excess Li1+tCo1-tO2-t with intermediate spin Co3+ is developed. The reversible water intercalation/deintercalation in the layered structure during charge/discharge effectively suppresses the layered-to-spinel phase transition with cycling.

An analysis of the electrochemical mechanism of manganese oxides in aqueous zinc batteries

Balaji Sambandam et al.

Summary: Aqueous rechargeable zinc batteries (ARZBs) have attracted significant interest due to their high energy density, safety, eco-friendliness, and sustainability. However, the diverse mechanisms behind the electrochemistry of zinc metal anodes in mildly acidic media have hindered the further development of ARZBs. This perspective seeks to clarify and find possible convergence of the conflicting electrochemical mechanisms for mildly acidic Zn-MnO2 batteries, and suggests future research directions and commercialization opportunities.
