Abstract null null Layered Li-rich oxides (LLROs) attract much attention due to their high capacities. However, the electrolyte decomposition and interfacial reactions especially driven by the catalysis effect of high-valance transition metal ions under high voltage cause severe performance recession, hindering their practical applications. Lithium fluoride (LiF) is an effective component in both cathode electrolyte interphase (CEI) and solid electrolyte interphase (SEI) films. In this work, lit...

Abstract The rising pursuit for green rechargeable energy storage devices desires novel electrode materials with cost-effective, environmental-friendly properties besides high electrochemical performance, boosting the rapid development of organic electrodes. However, the organic electrode materials in most reports can hardly be used in the real applications due to relatively poor electrochemical performance. Herein, by utilizing a smart supramolecular self-assembly between metal ions and ligands...

As a promising high energy density electrode material for rechargeable batteries, lithium (Li) metal is still suffering from air/water instability due to its highly reactive nature. In addition, the Li dendrite issue in Li metal batteries needs to be resolved to ensure the safety of batteries and for wide applications. Herein, we demonstrate that a simple compact GaOx layer formed using liquid metal (LM) can act as an artificial solid electrolyte interphase to block moisture and oxygen in the ai...

Solid Polymer Electrolytes (SPEs) exhibit great potential for application in high energy density solid-state lithium metal batteries owing to their excellent flexibility and high safety. However, the growth of lithium dendrites and poor interfacial contact between the electrolyte and electrode seriously hinder the wide commercial application. In this work, a composite solid electrolyte from halloysite nanotubes (HNTs), comb-like poly-e-caprolactone (PCL), and lithium bis(fluorosulfonyl)imide (Li...
