Graphene-sulfur composite as stable high energy capacity cathodes for Li-ion batteries

Green Car Congress

In a paper published in the ACS journal Nano Letters , they suggest that this material represents a promising cathode material for rechargeable Li-ion batteries with high energy density. However, it remains challenging to retain high and stable capacity of sulfur cathodes over more than 100 cycles.In Earlier post.) —Wang et al.
