Hydrogen-Bond-Assisted Solution Discharge in Aprotic Li-O2 Batteries

Qi Xiong et al.

Summary: This study proposes a new method to address cathode passivation in aprotic Li-O-2 batteries by utilizing hydrogen-bond-assisted solvation. An exemplary soluble catalyst called 2,5-di-tert-butylhydroquinone (DBHQ) is introduced to promote solution discharge and improve the discharge capacity and yield of Li2O2. The generalizability of this hydrogen-bond-assisted solvation approach is also verified with other soluble catalysts containing -OH or -NH groups.

Origin of structural degradation in Li-rich layered oxide cathode

Tongchao Liu et al.

Summary: Utilizing Li- and Mn-rich (LMR) cathode materials can increase battery energy density. However, voltage decay issues impede commercialization. In this study, it is revealed that nanostrain and lattice displacement accumulate continuously during operation, leading to structure degradation and oxygen loss, which cause rapid voltage decay. The heterogeneous nature of LMR cathodes results in pernicious phase displacement/strain. Mesostructural design is proposed as a strategy to mitigate lattice displacement and achieve stable voltage and capacity profiles.
