Fig. 5: Fast-charging mechanism of the InSnBi negative electrode.

a In situ XRD analysis of the InSnBi electrode cycled at a rate of 0.1 C at room temperature. b Li+ diffusion energy barrier of bulk Li3Bi, Li7Sn2 and Li13In3. c–e cryo-TEM images with different magnifications and the corresponding FFT pattern (after 5 cycles). f Schematics of interphases between crystals and amorphous materials. Li+ transport pathways and corresponding diffusion energies across crystalline-amorphous interfaces and between crystalline phases: g Li3Bi (110)/Li7Sn2 (010) and Li3Bi (110)/amorphous Li7Sn2, h Li3Bi (110)/Li13In3 (110) and Li3Bi (110)/amorphous Li13In3.
