In our TzG@Si/S@PAN full cell system, manipulating the cycling voltage window, specifically the cut-off voltages of 1.0 V and 0.8 V, resulted in distinct differences in stability and capacity as shown in Figure . This adjustment led to more pronounced changes in the real potential of the S@PAN cathode compared to the Si anode side (Figure ), underscoring the importance of studying the structural transformations and lithiation mechanisms of the S@PAN cathode. Such investigations could provide crucial insights into optimizing the S@PAN material for higher energy densities while ensuring its stability.
