A novel stacking sheet-like carbon (SSC) has been
synthesized by carbonizing the corn stalks and composited
with sulfur to prepare a cathode for lithium/sulfur batteries.
Scanning electronic microscopy observations showed the formation
of irregularly interlaced nanosheet-like structure
consisting SSC with uniform sulfur coating on its surface.
The SSC nanoflakes in the composite act as nanocurrent collectors,
favoring the charge carrier ion transport and electrolyte
diffusion. The interlaced SSC nanoflakes irregularly stack
together and form a three-dimensional network, which is beneficial
for both trapping soluble polysulfide intermediates and
rendering the electrical conductivity of the composite electrode...
