N2  - An efficient lithium?ion battery was assembled by using an enhanced sulfur?based cathode and a silicon oxide?based anode and proposed as an innovative energy?storage system. The sulfur?carbon composite, which exploits graphene carbon with a 3?D array (3DG?S), was synthesized by a reduction step through a microwave?assisted solvothermal technique and was fully characterized in terms of structure and morphology, thereby revealing suitable features for lithium?cell application. Electrochemical tests of the 3DG?S electrode in a lithium half?cell indicated a capacity ranging from 1200 to 1000?mAh?g?¹ at currents of C/10 and 1?C, respectively. Remarkably, the Li?alloyed anode, namely, Li?SiO?-C prepared by the sol?gel method and lithiated by surface treatment, showed suitable performance in a lithium half?cell by using an electrolyte designed for lithium?sulfur batteries. The Li?SiO?-C/3DG-S battery was found to exhibit very promising properties with a capacity of approximately 460?mAh?gs?¹ delivered at an average voltage of approximately 1.5?V over 200?cycles, suggesting that the characterized materials would be suitable candidates for low?cost and high?energy?storage applications.
