Lithium-sulfur (Li-S) batteries have attracted considerable attention due to their high energy density (2600 Wh kg⁻¹). However, its commercialization is hindered seriously by the low loading and utilization rate of sulfur cathodes. Herein, we designed the cellulose-based graphene carbon composite aerogel (CCA) self-standing electrode to enhance the performance of Li-S batteries. The CCA contributes to the mass loading and utilization efficiency of sulfur, because of its unique physical structure: low density (0.018 g cm⁻³), large specific surface area (657.85 m² g⁻¹), high porosity (96%), and remarkable electrolyte adsorption (42.25 times). Compared to Al (about 49%), the CCA displayed excellent sulfur use efficiency (86%) and could reach to high area capacity of 8.60 mAh cm⁻² with 9.11 mg S loading. Meanwhile, the CCA exhibits the excellent potential for pulse sensing applications due to its flexibility and superior sensitivity to electrical response signals.

锂硫 (Li-S) 电池因其高能量密度 (2600 Wh kg ^-1 ) 而备受关注。然而，硫正极的负载量和利用率低，严重阻碍了其商业化。在此，我们设计了基于纤维素的石墨烯碳复合气凝胶（CCA）自立电极，以提高锂硫电池的性能。CCA 有助于提高硫的质量负载和利用效率，因为它具有独特的物理结构：低密度 (0.018 g cm ⁻³ )、大比表面积 (657.85 m ² g ⁻¹)、高孔隙率(96%)和显着的电解质吸附(42.25倍)。与 Al（约 49%）相比，CCA 显示出出色的硫利用效率（86%），并且可以在 9.11 mg S 负载下达到 8.60 mAh cm ^{-2的高面积容量。}同时，由于其灵活性和对电响应信号的卓越灵敏度，CCA 在脉冲传感应用方面展现出卓越的潜力。
