摘      要：Lithium-sulfur batteries are emerging as sustainable replacements for current lithium-ion *** commercial viability of this novel type of battery is still under debate due to the extensive use of highly reactive lithium-metal anodes and the complex electrochemistry of the sulfur *** this research,a novel sulfur-based battery has been proposed that eliminates the need for metallic lithium anodes and other critical raw materials like cobalt and graphite,replacing them with biomass-derived *** approach presents numerous benefits,encompassing ample availability,cost-effectiveness,safety,and environmental *** particular,two types of biochar-based anode electrodes(non-activated and activated biochar)derived from spent common ivy have been investigated as alternatives to metallic *** compared their structural and electrochemical properties,both of which exhibited good compatibility with the typical electrolytes used in sulfur ***,while steam activation results in an increased specific surface area,the non-activated ivy biochar demonstrates better performance than the activated biochar,achieving a stable capacity of 400 mA h g^(−1)at 0.1 A g^(−1)and a long lifespan(400 cycles at 0.5 A g^(−1)).Our results demonstrate that the presence of heteroatoms,such as oxygen and nitrogen positively affects the capacity and cycling performance of the *** led to increased d-spacing in the graphitic layer,a strong interaction with the solid electrolyte interphase layer,and improved ion ***,the non-activated biochar was successfully coupled with a sulfur cathode to fabricate lithium-metal-free sulfur batteries,delivering a specific energy density of~600 Wh kg^(−1).
