资源简介：

Mn-based layered oxides, commonly used as cathodes in sodium-ion batteries, have limited lifespans due to unstable electrode-electrolyte interfaces, particularly at voltages above 4.3 V, which cause oxygen loss. This study presents an ultra-low concentration electrolyte (ULCE, ≤0.5M) to address these challenges and enhance the high-voltage performance of P2-type Mn-rich oxide cathodes. The research will also examine how cation and anion dopants, combined with ULCE, influence the structural evolution and electrode interphase during sodium (de)intercalation.
