Our innovative TzG@Si/S@PAN full cell system, first of its kind, demonstrated an areal capacity exceeding 2.0 mAh cm -2 and an energy density of 414.3 Wh kg -1 in a coin cell configuration. This study not only showcases a strategic overcoming of the well-documented limitations of high-energy-density batteries but also introduces a novel material synthesis approach promising for future battery technology. This work lays the groundwork for further development of stable, high-energy-density battery systems, crucial for advancing beyond traditional NMC-based energy storage systems.
