Fast‐Charging Solid‐State Li Batteries: Materials, Strategies, and Prospects

Advanced Materials, Год журнала: 2024, Номер unknown

Опубликована: Дек. 25, 2024

Abstract The ability to rapidly charge batteries is crucial for widespread electrification across a number of key sectors, including transportation, grid storage, and portable electronics. Nevertheless, conventional Li‐ion with organic liquid electrolytes face significant technical challenges in achieving rapid charging rates without sacrificing electrochemical efficiency safety. Solid‐state (SSBs) offer intrinsic stability safety over their counterparts, which can potentially bring exciting opportunities fast applications. Yet realizing fast‐charging SSBs remains challenging due several fundamental obstacles, slow Li + transport within solid electrolytes, sluggish kinetics the electrodes, poor electrode/electrolyte interfacial contact, as well growth dendrites. This article examines SSB through comprehensive review materials strategies (ceramics, polymers, composites), composites. In particular, methods enhance ion crystal structure engineering, compositional control, microstructure optimization are analyzed. also addresses interface/interphase chemistry mechanisms, providing insights guide material design interface next‐generation SSBs.

Abstract Progress in commercializing solid polymer electrolytes (SPEs) for lithium metal batteries (LMBs) has been impeded by challenges, like concentration polarization, non‐uniform Li + flux, and an unstable electrolyte interface (SEI), which contribute to dendrite formation. To address these issues, silica framework (SF)‐based single‐ion conductors are proposed, featuring a unique solvation channel composed of fluorinated segment, high‐dipole zwitterion, rotation‐motion‐driven ion‐hopping medium. This design promotes low resistance at the cathode/electrode interface, suppresses growth anode/electrolyte maintains uniform flux. results show that continuous ion channels within robust enhance Li‐ion dissociation transport, achieving high ionic conductivity (σ DC = 8.8 × 10 −4 S cm −1 ), modulus 0.9 GPa, transference number (≈0.83), extended electrochemical stability window (up 5.2 V) 25 °C. fosters formation hybrid organic/inorganic SEI layer 2 CO 3 , LiF, O, enabling ultra‐stable plating/stripping over 4000 h 0.1 mA −2 . Furthermore, full cells demonstrate excellent rate performance long‐term cycling capacity retention (81% Li||LFP 86% Li||NCM811 after 400 cycles 1 C) coulombic efficiency, offering promising strategy stable LMBs.
