Synthesis Of Materials

AbstractThe electrochemical discharge mechanism is reported for all-solid lithium sulfur batteries. Upon milling with carbon fibers, the solid electrolyte used within the cathode composite becomes electrochemically active. Analysis with Raman spectroscopy and XPS revealed the importance of bridging S-S bond formation and breaking in lithium polysulfidophosphates during electrochemical lithiation of the active solid electrolyte. Remarkably, when sulfur is introduced as an active material in the cathode composite, lithium polysulfides are formed as an intermediate product before full lithiation into lithium sulfide. The synthesis of materials based on bridging S-S bonds is an important avenue to the design of new cathodes for all-solid batteries.

Using Orange Peels as Raw Material, a Stacking Structured Carbon Material has been Synthesized through Carbonizing and Activating Process. an Orange Peel Carbon/sulfur (OPC/S) Composite as a Cathode for Rechargeable Lithium/sulfur (Li/S) Batteries is Designed by Loading Sulfur into the Orange Peel Carbon (OPC) via Simple Impregnation and Heat Treatments. the OPC/S Composite Exhibits a High Discharge Capacity of 1100 mAh g−1 at 0.1 C, which is 23% Higher than that of Pristine Sulfur. Moreover, OPC/S Shows much Better Rate Capability and Excellent Cyclability. this Enhanced Electrochemical Performance could Be Attributed to the Thin Sheets and Irregular Wrinkled Surface of the OPC, which Act as a Conductor to Provide a Highly Conductivity and Short Li+ Diffusion Distance, as well as Absorbs Polysulfides.
