Fig. 1: The design of the architected continuum alloy concept.
a The conventional negative electrode architectures—PSA and PMFA with their advantages and disadvantages. b By adopting the advantages of the PSA and PMFA, the architected continuum alloy is designed, composed by multiple metal elements, featuring bi-continuous MIEC percolation and soft-soft contact to buffer the mechanical stress and to stop the crack-based degradation. c Deformation mechanism maps for various materials at 25 °C (TH is homologous temperature, where TH = Tw/Tm=working temperature/melting temperature). The mechanical data and melting points of these materials are obtained from ref. 17 and the Material Project (materialsproject.org), accessed 2023-11-15. The In, Sn, and Bi were screened out with sufficient flexibility and creep behavior. d Schematic diagram of lithiation process and advantages of the designed InSnBi negative electrode.
