Structural characterization of an amorphous VS4 and its lithiation/delithiation behavior studied by solid-state NMR spectroscopy
Keyword(s):
Amorphous VS4 (a-VS4) is prepared from the crystalline one (c-VS4). Li insertion into a-VS4 involves the amorphous–amorphous phase transition from Peierls-distorted chain-like structure to [VS4]3− tetrahedra-based structure.
