Fig. 6: Electrochemical characterization.

Nyquist plots of the Li–S battery at same depth of discharge (2.3 V) but different cycles (100–500) for electrodes: a N/S doped laser synthesized doped graphene (LIG) with micro-MoS₂ loading, b N/S doped laser synthesized doped graphene (LIG) with nano-MoS₂ loading and c proposed equivalent circuit for cell.
