In recent years, metal compound-based heterojunctions have received increasing attention from researchers as a candidate anode for lithium/sodium-ion batteries, because heterojunction anodes possess unique interfaces, robust architectures, and synergistic effects, thus promoting Li/Na ions storage and accelerating ions/electrons transport.
The grains of indium at the interface to the SE were smaller (thickness ≈20 µm) and showed a finer microstructure, while the grains of both indium and InLi expanded from the current collector to the SE interface in a columnar shape.
SEM images are complemented by phase and IPF maps (given parallel to the y-direction) for indium and intermetallic InLi to reveal their microstructure using EBSD. The WE (stripped) and CE (plated) of unidirectional galvanostatic experiments at 0.5 mA cm −2, 25 °C, and 30 MPa with a cut-off potential of 1 V were studied (Figure 3).
In the pristine Li/In stacked (top), there is a distinct lateral phase separation between indium metal and InLi. The outer (left) side is composed of indium, while the inner side (right) consists of InLi. This separation is due to the different diameters of the indium and lithium metal foils used during electrode preparation.
Summarizing various reports in the literature, In–Li anodes suffer from being mechanically stiffer – compared to pure indium – due to the mechanical properties of the InLi phase (Young's modulus of 46.1 GPa and hardness of 1.82 GPa).
