Silicon (Si)-based anode materials are considered the most promising next-generation anodes for lithium-ion batteries (LIBs). Nonetheless, in practical applications, Si anodes have encountered numerous challenges. A homogeneous silicon carbide (SiC) dispersoid was synthesized within the Si-based alloy using vacuum melting, sand milling, and Flash joule heating procedures. The integration of SiC facilitates the simultaneous resolution of key issues: low intrinsic conductivity, unstable solid electrolyte interphase (SEI), and significant volume expansion, which is accomplished by creating a swift and uniform charge-transport network, enhancing interfacial kinetics, and bolstering the mechanical integrity of the electrode, which is attributed to the synergistic effect of a highly conductive network formed by the in-situ generated defective SiC and the metallic phases (Sn/Bi), SiC's advantageous interfacial characteristics, exceptional mechanical strength, and dispersion strengthening effect. The half-cell exhibits an impressive capacity of 1881.69 mAh g−1 and maintains steady cycling for 400 cycles at a current density of 1.5 A g−1. The full cell utilizing Li1.2Ni0.13Co0.13Mn0.54O2, demonstrates a capacity of 251.71 mAh g−1 following 80 cycles at 0.33 A g−1. Meanwhile, excellent cycling stability is attained in all-solid-state batteries, delivering a capacity retention of 81.1% over 150 cycles. This work introduces an innovative triple synergistic mechanism that significantly enhances the electrochemical performance of Si-based anodes, facilitating their efficient manufacture and offering important insights for future investigations.

As one of the most promising solid-state polymer electrolytes (SPEs), Polyacrylonitrile (PAN)-based SPEs suffer from unstable interfaces due to their highly reactivity with lithium metal anode. Here, the molecular chain of the PAN polymer is tailored through surface-basicity-guided reactions of Li7La3Zr1.4Ta0.6O12 (LLZTO) and an electrostatic shielding effect of 1-Ethyl-3-methylimidazolium cation (EMIM⁺), effectively mitigating its reactivity with Li. The alkalinity of LLZTO catalyze PAN dehydrocyanation, transforming –CN groups to π-conjugated –C=N/–C=C– bonds, thus decreasing its inherent reactivity with the Li metal. Then, the positive EMIM⁺ with an electron-delocalized π-network electrostatically connect with polarized –C=N sites, shielding the direct contact of –CN groups with Li, further alleviating parasitic reactions. As a result, the Li//Li symmetric cells deliver high critical current density of 3.0 mA cm−2 and maintain stable Li plating/stripping over 2000 h. The Li//LFP cell delivers a high capacity retention of 87.53% after 1200 cycles at 2C, and the pouch battery presents excellent cycling and safety performance. This work provides a promising approach to enable the stable operation of solid-state lithium metal batteries via incorporating the electron-delocalized π-network.

Lithium (Li) metal is considered the ultimate anode for next-generation high-energy-density batteries, but its practical deployment is limited by uncontrolled dendrite growth and severe active Li loss under lean-lithium conditions. Although 3D hosts can mitigate these issues, conventional designs fail to precisely regulate ion transport and deposition kinetics. Herein, we design a synergistic thermodynamic-kinetic gradient membrane host that enables spatio-temporal modulation of Li deposition by hot-pressing three NIPS-derived membranes: ZnO-doped bottom layer, Fe2O3-doped intermediate layer, and pristine CNT@PVDF top layer. The intrinsic binding-energy difference (ΔEb) between layers establishes lithiophilic gradient to provide spatial control, thermodynamically drives top-down Li-ion migration. Meanwhile, the distinct lithiation potentials of ZnO and Fe2O3 establish a broadened, multi-step reaction window that provides multiple pathways for Li-ion diffusion and facilitates time-dependent interfacial evolution via conversion/alloying. In situ TEM reveals the formation of multi-functional LiZn/Li2O and Fe/Li2O interfaces, enhancing ion/electron transport and providing durable kinetic regulation for subsequent plating. Consequently, the Li||ZFCP half-cell delivers an average Coulombic efficiency of 97% over 700 cycles with minimal polarization, and the full cell paired with LiFePO4 sustains 750 cycles at a low N/P ratio of 1.6. This study establishes a theory-guided paradigm for designing highly stable and practical Li metal anodes.
