Abstract: Abstract This invention presents an ultra-high capacity lithium-selenium (Li-Se) battery employing a selenium-carbon aerogel nanostructured cathode for advanced energy storage applications. The carbon aerogel exhibits a high specific surface area of 600-850 m2 g pore volume o f-1.2-1.8 cm3 g_l, and electrical conductivity in the range of 10-25 S cm-1, enabling efficient charge transport. Selenium is incorporated at 65—80 wt% with uniform nanoscale dispersion, reducing agglomeration and accommodating volume variation below 10% during cycling. The cell delivers an initial discharge capacity of 680-750 mAh g_i at 0.1-0.2 C, with a stable reversible capacity o f-600 mAh g_l after 250 cycles and capacity fading below 0.05% per cycle. The system achieves an energy density of 400—520 Wh k g 1 and a power density exceeding 900 W kg-1. Electrochemical impedance spectroscopy indicates low charge-transfer resistance (-30-50 and improved ion diffusion kinetics. The cathode demonstrates high coulombic efficiency (— 99.2%) and strong suppression of polyselenide shuttle due to chemical confinement within the aerogel matrix. Rate performance remains stable up to 3 C, retaining over 70% of its initial capacity. The Li+ diffusion coefficient is estimated in the order of 10-9- 10"11 cm2 s_1, confirming fast electrochemical kinetics. This innovation significantly enhances cycling stability, conductivity, and overall electrochemical performance, making it a strong candidate for next-generation high-energy rechargeable battery systems.
