The use of activated bio-carbon derived from "Posidonia oceanica" sea-waste for Lithium-Sulfur batteries development

Popis výsledku v původním jazyce

Lithium-Sulfur Batteries is promising energy storage systems due to their superior capacity and energy density. A promising solution for drawbacks such as low sulfur utilization and cycling stability is the use of porous carbon as sulfur carrier. On the other hand, cyclic economy and green ideas is of great importance nowadays. Carbon-sulfur cathodes from waste valorization, abundant, and low-cost precursors is an attractive approach. Herein, an activated carbon (AC-Poc) derived from &quot;Posidonia oceanica&quot; sea-waste, was studied as a matrix for the development of a novel carbon-sulfur composite cathode (AC-Poc/S) for the first time. AC-Poc can be used as an effective sulfur host, due to its high specific BET surface area (1264 m2BULLET OPERATORgMINUS SIGN 1) hierarchical porous structure, and total pore volume 0.81 cm3BULLET OPERATORgMINUS SIGN 1. AC-Poc/S reveals an outstanding initial capacity of 1539 mAhBULLET OPERATORgMINUS SIGN 1 as cathode material, combined with high reversible capacity at 0.2 C. Furthermore, the discharge capacity of 390 mAh/g at 2 C reveals good rate capability, even at increased C-rate. AC-Poc/S composite exhibits excellent sulfur utilization (92 %) alongside with sufficiently well electrochemical performance. These results combined with the easy synthesis method of the activated carbon from an abundant and low-cost precursor make AC-Poc/S a very promising material for LSBs applications.
