Topological Insulator Layered Bi2Te3 Based 3D-Printed Nanocarbon Electrode for Rechargeable Aqueous Ammonium-Ion Battery

Popis výsledku v původním jazyce

Rechargeable aqueous ammonium-ion batteries (AIBs) hold great potential forsustainable energy storage due to their low cost, high safety, and outstandingelectrochemical characteristics. However, their development is hindered bythe limited availability of suitable anode materials. Herein, we propose for thefirst time the use of a topological insulator, bismuth telluride (Bi2Te3), as anovel anode material integrated onto a 3D printed nanocarbon electrode(3DpCE) for NH4+ ion storage. Taking advantage of the 3D porous frameworkand the non-metallic nature of NH4+ ions, Bi2Te3@3DpCE exhibits a higherdischarge capacity of 128 mAh g−1 at 0.5 A g−1 with lower polarization, andbetter cycling stability compared to metallic ions such as Li+ and Na+.Through various ex-situ characterizations, we also reveal the plausible NH4+storage mechanism. A full cell based on a “rocking-chair” configuration isconstructed using copper hexacyanoferrate (CuHCF) as the cathode. TheCuHCF@3DpCE//Bi2Te3@3DpCE full cell in 1 M (NH4)2SO4 electrolytedelivers a high energy density of 134.8 Wh kg−1 and a power density of 1800 Wkg−1, outperforming previously reported AIBs. Furthermore, the recyclabilityof the used 3D printed nanocarbon electrode is demonstrated, highlighting itseco-friendly potential. These findings offer a promising pathway towardhigh-performance, sustainable, next-generation AIB technologies.
