In the endless search for superior and green power sources, lithium sulphur (Li-S) batteries held the promise of opening up a new era of long lasting and high energy storage systems for variety of applications. They might envisage remarkable benefits in utilising polymer electrolytes instead of liquids in terms of safety, low-cost and gravimetric/volumetric energy densities. In this work, for the first time, nanoscale microfibrillated cellulose-laden polymer systems are prepared using a thermally induced polymerisation process and tested as electrolyte separator in a Li-S rechargeable battery that contains sulphur-carbon composite based cathode. The polymer electrolyte demonstrates excellent ionic conductivity, thermal stability and most importantly stable interface towards lithium metal. While comparing our earlier report with non-aqueous liquid electrolyte, the present cell based on the abundant truly-natural cellulose-based polymer electrolyte as separator exhibits better cycling stability, higher specific capacity, superior Coulombic efficiency and rate capability at ambient conditions.
