Abstract The germanium (Ge) anode attains wide attention in lithium‐ion batteries because of its high theoretical volumetric capacity (8646 mAh cm −3 ). However, the huge volume expansion (≈230%) results poor electrochemical performances. strategies reported literature to solve issue often cause a low packing density, lowering capacity. Here, pressure‐induced route is proposed fabricate Ge architecture, which nano‐sized (≈15 nm) encapsulated by robust TiO 2 and highly conductive carbon, offer advantages stress–strain characteristic, thickness change, electrical conductivity (463.2 S m −1 ), Li‐ion diffusion coefficient (9.55 × 10 −9 –8.51 −12 s tapping density (1.79 g As result, dense architecture obtains outstanding capacities 3559.8 at 0.1 A 2628.2 20 , along with excellent cycling life over 5000 cycles . Remarkably, full cell achieves energy 1760.1 Wh L impressive fast‐charging performances long life. This work provides new synthesis strategy deep insight into design high‐volumetric alloy‐based lithium‐ion‐battery anodes.

Abstract The electrochemical performance of Si anodes for lithium‐ion batteries (LIBs) is primarily influenced by the stress–strain and transport dynamics. However, traditional Si/carbon composites often fail to well balance these two factors. Herein, a hierarchically porous silicon/carbon composite (denoted as pSi@void@NMC) with high lithium storage capacity developed under guidance finite element analysis, where (pSi) nitrogen‐doped mesoporous carbon (NMC) used yolk shell, respectively. internal external cultivation design endows pSi@void@NMC fast transfer kinetics, effective stress‐buffering, low volume expansion, superior mechanical stability. Compared core–shell pSi@NMC bare pSi electrodes, resulting anode demonstrates reversible 1769.8 mAh g −1 after 300 cycles at 0.2 A exceptional cycling stability only 0.016% decay rate per cycle. In situ ex characterization results further confirm its reversibility Li + insertion/extraction during reactions benefiting from formation inorganic LiF‐rich SEI film. Moreover, also shows good potential full‐cell applications. These findings provide facile concept research strategy addressing stress fractures inadequate kinetics Si‐based materials high‐performance LIBs.

Abstract While the high‐entropy strategy is highly effective in enhancing performance of materials across various fields, an optimal methodology for selecting component elements optimization still lacking. Here findings on uncovering element selection rules rational design alloy anodes with exceptional lithium storage are reported. It investigated screening by modifying stable diamond‐structured Ge P to induce a tetrahedrally coordinated sphalerite structure enhanced metallic conductivity, further stabilized incorporating Zn and other elements. Moreover, both theoretical experimental results confirm that Li‐storage improves increasing atomic number: BZnGeP 3 < AlZnGeP GaZnGeP InZnGeP . ‐based electrodes demonstrate highest Li‐ion affinity, fastest electronic transport, largest capacity reversibility, best mechanical integrity. Further based above criteria leads high entropy conductivity like GaCuSnInZnGeP 6 , GaCu(or Sn)InZnGeP 5 CuSnInZnGeP InZnGePSeS(or Te), 2 S(or Se) which show superior performances. The excellent phase stability attributed their configurational entropy. This study offers profound insights into alloy‐based batteries, providing guidance reference combination functional materials.
