Abstract Both lattice oxygen release and the migration of transition metal (TM) ions challenge cyclability Li‐rich Mn‐based layered oxide (LMO) cathodes by inducing irreversible phase transitions. In this work, oxygen‐vacancy‐assisted dual functional surface coatings cathodes, including a spinel‐over‐phase Li 3 PO 4 layer are fabricated for lithium‐ion batteries (LIBs). The role optimized interface is mainly focused. Specifically, during process reorganized structure, vacancies function as...
Copper ferrites are emerging transition metal oxides that have potential applications in energy storage devices. However, it still lacks in-depth designing of copper based anode architectures with enhanced electroactivity for lithium-ion batteries. Here, we report a facile synthesis technology anchored on reduced graphene oxide (CuFeO2@rGO and Cu/CuFe2O4@rGO) as the high-performance electrodes. In resulting configuration, offers continuous conductive channels electron/ion transfer high...

Li-Rich Layered Oxide Cathodes In article number 2400670, Xifei Li and co-workers report the oxygen-vacancy-assisted dual functional coatings on surface of Li-rich layered oxide cathodes. Benefiting from optimized structure, irreversible phase transition cathodes is effectively suppressed upon cycling, thereby leading to competitive battery performance.
Constructing a stable cathode-electrolyte interphase (CEI) is crucial to enhance the battery performance of Li-rich Mn-based oxide (LMO) cathodes. To achieve an ideal CEI, gas-phase fluorination technique proposed pre-structure robust LiF layer (≈1 nm) on LMO surface. The designed effectively modulates electric field distribution electrode surface and mitigates undesirable side reactions between electrolyte, thereby promoting formation uniform LiF-rich CEI LMO-F-1. optimized facilitates...
