Disordered materials (DMs) have become promising in the advancement of lithium-ion batteries (LIBs). Their disordered, open structure is conductive to facilitate efficiency storage. DMs with tunable compositions also possess abundant defects that can interact Li+, further enhancing their electrochemical performances LIBs. Yet, revealing structural origin superior properties DM-based LIBs remains a challenge. In this article, we review recent advances development components for LIBs, such as anodes, cathodes, coating layers, and solid-state electrolytes. We describe primary preparation characterization methods utilized DMs, while describing mechanisms involved DM synthesis. This article addresses correlation between performances. Moreover, elucidate challenges future perspectives summarize key advantages LIB performance over crystalline counterparts, providing insights developing through tailored development.

Abstract Lithium fluoride (LiF) facilitates robust and fast‐ion‐transport solid electrolyte interphase (SEI) in lithium metal batteries. Fluorinated solvents/salts are ubiquitously employed to introduce LiF into SEI through electrochemical decomposition, but this approach is usually at the expense of their continuous consumption. A direct fluorinate that employs crystal limited by its poor solubility current battery formulation. Dissolving high‐dielectric‐constant solvents, like ethylene carbonate (EC) nearly neglected. Herein, feasibility directly fluorinating addition aprotic with assistance EC verified, mechanisms fluorination anti‐acidification explored. The dissolved encapsulated solvent‐/salt‐derived organic skins promote fluorinated SEI. Meanwhile, presence alters hazardous thermodynamic equilibrium, suppressing production acid species mitigate acidification degradation. Such collective benefits yield a capacity retention ratio ≈88% after 150 cycles high areal (4.5 mAh cm −2 ) Li||NCM622 cells. This facile effective contributes an in‐depth understanding formation rational design well‐performing

Abstract In solid‐state lithium metal batteries (SSLMBs), the inhomogeneous electrolyte‐electrode interphase layer aggravates interfacial stability, leading to discontinuous ion/charge transport and continuous degradation of electrolyte. Herein, we constructed an anion‐modulated ionic conductor (AMIC) that enables in situ construction electrolyte/electrode interphases for high‐voltage SSLMBs by exploiting conformational transitions under multiple interactions between polymer salt anions. Anions modulate decomposition behavior supramolecular poly (vinylene carbonate) (PVC) at electrode interface changing spatial conformation chains, which further enhances ion stabilizes morphology. addition, AMIC weakens “Li + ‐solvation” increases Li vehicle sites, thereby enhancing lithium‐ion number ( t =~0.67). Consequently, || LiNi 0.8 Co 0.1 Mn O 2 cell maintains about 85 % capacity retention Coulombic efficiency >99.8 200 cycles a charge cut‐off voltage 4.5 V.
