Study of Room Temperature Solid Polymer Electrolyte for Lithium Sulfur Battery

Natural materials as the basis for solid electrolyte development can sustainably innovate for high-performing batteries. A sucrose based solid polymer electrolyte was developed, displaying high room temperature ionic transport properties, with ionic conductivity of 4.28 x 10(-4) S cm(-1) and lithium ion transference number of 0.76. Lithium sulfur batteries assembled achieve an initial discharge capacity of 1302.7 mAh g(-1) and 644.2 mAh g(-1) in the 94 th cycle at 25 degrees C and 0.1C, and 517.5 mAh g(-1) in the 200 th cycle at 45 degrees C and 0.2 C. These demonstrate the potential for nature derived materials in green energy innovation.
