| Description |
NASICON frame work Na3V2(PO4)3 (NVP), wrapped by nitrogen and sulfur doped bio-carbon matrix
derived from human hair (HHC) has been investigated for its anode behavior in SIBs. Basically, NVP is
bestowed with a crystal structure of 3D open framework and a moderate theoretical capacity of 118 mAh
g�1, which are the twin advantages and motivation behind the selection of this material. Prepared
through a simple, scalable and facile method, the key problems associated with pristine NVP electrode
material, such as inferior conductivity and severe volume change have been mitigated to a great extent
through the formation of a composite containing HHC. Herein, HHC is a cheap and eco-friendly composite
additive, obtained from a universal bio-waste, viz., human hair and hence NVP/HHC qualifies itself
as a green composite. Interestingly, NVP/HHC-10 (in-situ) and NVP/HHC-20 (ex-situ) anodes show
excellent electrochemical performance in terms of cycling stability up to 500 cycles and rate capability @
2 A g�1, which are superior than similar category NVP anodes reported in the literature. Further, post
cycling structure and morphology of NVP/HHC composite anodes evidence the appreciable stability
bestowed with the select composition, which is found to get maintained upon extended cycles and even
after rate capability test.
