A multivalent aluminum metal anode (AMA) can deliver high specific/volumetric capacities of 2,980 mA h g-1/8,040 mA h cm-3 in an ionic liquid-AlCl3 electrolyte system. However, the large concentration overpotential of AMA induced by its distinctive anion-mediated aluminum metal redox mechanism causes poor rate capabilities and insufficient round-trip efficiencies, limiting its application in rechargeable aluminum batteries (RABs). In this paper, we report a novel strategy of using a carbonaceous catalytic host electrode for high-performance AMA. The targeted carbon electrode should have a high active surface area, strong interaction with ionic charge carriers, well-developed electronic pathways, and macroporous internal structures to accommodate incessantly deposited metals. In this regard, a 3D-structured carbon nanotube forest (CNT-F) was fabricated from waste polyolefins by a simple pyrolysis process as an optimal candidate for the catalytic host electrode. The waste-induced pyrolytic CNT-Fs (WP-CNT-F) had large open surface areas covered with multitudinous intrinsic carbon defects, on which uniform aluminum reduction reactions occurred concurrently, leading to significantly lower concentration overpotentials. In addition, the WP-CNT-Fs exhibited high coulombic efficiencies of 99.4-99.8% over a wide range of current densities (0.5-4.0 mA cm-2) and great cycling stabilities over 1,000 cycles. The superior electrochem. performances of the WP-CNT-F-based AMA were demonstrated in the RAB full cells with a com. graphite cathode, affording a high specific energy and a high power d. of ∼132.2 W h kg-1electrode and 10,230 W kg-1electrode, resp., along with outstanding cycling stabilities over 2,500 cycles.1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) were involved in the experimental procedure.
1-Ethyl-3-methyl-1H-imidazol-3-ium chloride(cas: 65039-09-0) is an imidazolium chloride ionic liquid that can be used as:a starting material for the preparation of 1-ethyl-3-methylimidazolium chloride/tetrafluoroborate (EMI.Cl.BF4) molten salt for electrochemical studies; a solvent as well as catalyst for the depolymerization of oak wood lignin.Related Products of 65039-09-0
