Abstract:
Lithium-rich layered oxide (LLO) with a large specific capacity (>250 mAhg?1) and the wider voltage window (2.0–4.8 V) delivers an energy density of about 1000 Wh/kg. However, oxygen release from the surface of LLO and decomposition of electrolyte solvents leads to increased electrode-electrolyte interface resistance. To achieve the maximum energy density of LLO, it becomes mandatory to protect the surface structure and simultaneously activate the cationic and anionic redox reaction.
