Summary: Alloying elemental foil, such as Sn, Al, In, etc., as anodes in high-energy-density Li-ion batteries shows great promise due to their attractive capacities, low cost, and easy processability. However, poor electrochemical performance is caused by abundant Li loss, uneven electrochemical reactions, and continuous side reactions. In this study, a conformal heterogeneous Li-alloy interface alloying elemental foil (Sn/Li-LA) was constructed, which could suppress side reactions and homogenize electrochemical reactions. The cycle life and efficiency of batteries were significantly improved.

Summary: Researchers synthesized a lithiophilic 3D copper foam host with uniformly distributed nano-flower-like ZnO particles (CuF/ZnO) and obtained a composite lithium metal anode (CuF/Li2O-LiZn@Li) containing Li2O, LiZn alloy, and pure Li by infusion of molten Li. The composite lithium metal anode, benefiting from the 3D structure of copper foam and the lithiophilicity of ZnO sites, can restrain volume alteration and regulate uniform lithium deposition. The symmetrical cells of the composite lithium metal anode exhibit a 1600-hour long cycle life with a low polarization voltage of 15 mV, and the Coulombic efficiency can maintain about 97.8% at 1.0 mA·cm(-2), 1.0 mAh·cm(-2).

Summary: SiOx anode has a more durable cycle life than Si and can replace conventional graphite. However, the influence of carbon microstructure on Li-ion storage behavior in SiOx/C anode has been insufficiently considered. This study shows that the disorder of carbon can determine the ratio of inter- and intragranular Li-ion diffusions. Rational disorder-induced intergranular diffusion can benefit the phase transition of SiOx/C and improve its electrochemical performance.

Summary: A multilayer reconstruction strategy is employed to suppress the evolution of lattice oxygen and structure transformation in layered lithium-rich manganese-based oxide (LRMO) through facile pyrolysis. The multilayer interface is visually observed using advanced electron microscopy techniques. The suppressed evolution of lattice oxygen during initial charging eliminates the variation in unit cell parameters and prevents lattice distortion during long cycling, leading to improved Coulombic efficiency, rate capacity, and long-term stability of the modified LRMO. This study provides a surface reconstruction strategy to suppress anionic redox and offers insights for material design in high-performance lithium-ion batteries.
