Layered transition metal oxides (LTMOs) are attractive cathode candidates for rechargeable secondary batteries because of their high theoretical capacity. Unfortunately, LTMOs suffer from severe capacity attenuation, voltage decay, and sluggish kinetics, resulting irreversible lattice oxygen evolution unstable cathode-electrolyte interface. Besides, accumulate surface residual alkali species, like hydroxides carbonates, during synthesis, limiting practical application. Herein, a universal strategy is suggested to in situ convert into stable polymer coating layer LTMOs, thus turning wastes treasure. The formation process involves NH4F treatment consume alkali, then utilizing generated fluorides induce the ring-opening polymerization tetrahydrofuran. Implementing this Li-rich Mn-based materials (LRM) results notable reduction hysteresis, along with enhanced kinetics cycling stability lithium-ion batteries. With encapsulation, release layered-to-spinel phase LRM significantly alleviated minimal mechanical degradation parasitic reactions. Such can also be applied air-sensitive sodium-rich sodium-ion batteries, which showcases superior universality. This work might provide promising solution overcome interfacial instability issues

Abstract Lithium‐ion batteries (LIBs) have dominated the market for a long time. However, scarcity of lithium resources has sparked concerns about future energy storage devices, leading many researchers to turn their attention other such as sodium‐ion (SIBs), potassium‐ion (KIBs), zinc‐ion (ZIBs), and so on. Among them, SIBs attracted widespread from due abundant sodium resources, high safety, excellent low‐temperature performance. Because cathode battery determines density, cycle life, charge/discharge rate, cost, research on cathodes is particularly important. Layered oxide cathodes, with periodic layered structure, good electrical conductivity, two‐dimensional ion transport channels, are regarded most promising materials SIBs. Currently, main issues facing include irreversible phase transitions, air sensitivity, insufficient surface residual alkali, migration dissolution transition metals. The key solving these problems lies in development new generation high‐performance cathodes. Hence, we review current progress various optimizing strategies, finally summarize provide an outlook trends image
