Overlithiation lithium-rich Mn-based oxide as cathode pre-lithiation agent towards high-energy-density batteries

Strategies for developing layered oxide cathodes, carbon-based anodes, and electrolytes for potassium ion batteries

“…Manganese-based layered oxide is the most compelling cathode among low-cost cathodes. 65–67 So far, researchers have carried out plenty of work on this cathode, including the investigation of structural modification, composite electrodes, and the electrode/electrolyte interface. The P-phase manganese-based layered oxide cathode shows stable coulombic efficiency at the initial stage of cycling.…”

Pre‐Lithiation Technology for Rechargeable Lithium‐Ion Batteries: Principles, Applications, and Perspectives

“…Generally higher potential cathode additive has better chemical stability than anode additives, and the most used are ternary materials, binary materials and composites. [108,109] The ternary material Li x M y O z (M=Ni, Co, Fe, etc.) is used as a cathode pre-lithiation additive by extracting Li ions for transfer to the anode to compensate for the consumption of active lithium.…”

Implanting Transition Metal into Li2O‐Based Cathode Prelithiation Agent for High‐Energy‐Density and Long‐Life Li‐Ion Batteries

“…[7] Briefly speaking, the cathode prelithiation agents ought to have enough lithium storage capacity, which should be able to release the stored lithium ions below the charge cut-off potential of cathode. [8] Several representative Li-rich compounds have been introduced as cathode prelithiation agents, including Li 2 O 2 , [9] Li 2 S, [10] antifluorites (Li 2 O, [11] Li 6 CoO 4 , [12] Li 5 FeO 4 , [13] ), and Li-rich layered oxides (Li 2 MnO 3 -LiMO 2 [14] (M = Ni, Co, Mn)). With its highest theoretical gravimetric energy density (1794 mAh/g, 2.91 V vs. Li/Li + ), Li 2 O is considered the optimal choice for the candidate of cathode prelithiation agent.…”
