Summary: This study combines first-principles calculations and scanning transmission electron microscopy to investigate nano-features in an aged Al-Cu-Li-Zr alloy. Excess Li is found to segregate to the early-precipitated beta'(L1(2)-Al3Zr) nano-phase and form a tentative delta'(L1(2)-Al3Li) shell. These findings provide insights into experimental observations and have implications for the design of Al-Li alloys.

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: Silicon-based anode materials for lithium batteries face significant challenges with regard to structural instability and insufficient electron/ion conductivity. In this study, a three-dimensional silicon/carbon framework (CHSP) is proposed to address these issues. By effectively fixing nano-Si particles in an interconnected porous conducting network, the CHSP material enhances ion/electron transport and buffers the volume change of silicon. The resulting CHSP demonstrates satisfactory rate performance and high reversible capacity, making it a promising approach to improve the performance of silicon anodes.

Summary: The improvement of high-temperature mechanical properties of W-Cu based composites was achieved through the combined effects of solid solution, dispersed nano-precipitation, and highly stabilized nanostructure in the W-Cu-Cr-ZrC composite. The high thermal stability of the nanostructure endowed the composite with a compressive strength of 1150 MPa at 900 degrees C, approximately four times higher than that of the binary coarse-grained W-Cu composite. The crucial role of microstructural stability of the W phase skeleton in the overall strength of the W-Cu based composites was revealed.

Summary: An in-situ reaction strategy was proposed to synthesize a multicomponent nanocrystalline W-Cu based composite co-doped with Cr and WC. The material obtained has a homogeneous distribution of various phases and shows significant improvements in hardness and wear resistance compared to conventional coarse-grained W-Cu composite. This enhancement is attributed to the restricted formation and delamination of the mechanically mixed layer, as well as the increased strain gradient induced by the hard phases on the worn surface.
