  • advanced rechargeable Aluminium Ion battery with a high quality natural graphite cathode
    Nature Communications, 2017
    Co-Authors: Di Yan Wang, M Gong, Chuan Yu Wei, Mengchang Lin, Chunjern Pan, Hung Lung Chou, Hsin An Chen, Chunze Yuan
    Abstract:

    Recently, interest in Aluminium Ion batteries with Aluminium anodes, graphite cathodes and Ionic liquid electrolytes has increased; however, much remains to be done to increase the cathode capacity and to understand details of the anIon–graphite intercalatIon mechanism. Here, an Aluminium Ion battery cell made using pristine natural graphite flakes achieves a specific capacity of ∼110 mAh g−1 with Coulombic efficiency ∼98%, at a current density of 99 mA g−1 (0.9 C) with clear discharge voltage plateaus (2.25–2.0 V and 1.9–1.5 V). The cell has a capacity of 60 mAh g−1 at 6 C, over 6,000 cycles with Coulombic efficiency ∼ 99%. Raman spectroscopy shows two different intercalatIon processes involving chloroaluminate anIons at the two discharging plateaus, while C–Cl bonding on the surface, or edges of natural graphite, is found using X-ray absorptIon spectroscopy. Finally, theoretical calculatIons are employed to investigate the intercalatIon behaviour of choloraluminate anIons in the graphite electrode. Rechargeable Aluminium Ion batteries are an emerging class of energy storage device. Here the authors reveal high-quality natural graphite as a promising cathode for Al-Ion batteries, also identifying chloroaluminate anIon intercalatIon in graphite by Raman spectroscopy.

    Abstract:

    An Aluminium-Ion battery is reported that can charge within one minute, and offers improved cycle life compared to previous devices; it operates through the electrochemical depositIon and dissolutIon of Aluminium at the anode, and the intercalatIon/de-intercalatIon of chloroaluminate anIons into a novel graphitic-foam cathode. The low cost and useful electrical properties of Aluminium suggest that rechargeable Al-Ion batteries could offer viable and safe battery technology, but problems with cathode materials, poor cycling performance and other complicatIons have persisted. Here Hongjie Dai and colleagues describe an Al-Ion battery that can charge within one minute and offers substantially improved cycle life with little decay in capacity compared to previous devices reported in the literature. The battery operates through the electrochemical depositIon and dissolutIon of Al and intercalatIon/de-intercalatIon of chloroaluminate anIons into a novel 3D graphitic foam cathode using a non-flammable Ionic liquid electrolyte. The development of new rechargeable battery systems could fuel various energy applicatIons, from personal electronics to grid storage1,2. Rechargeable Aluminium-based batteries offer the possibilities of low cost and low flammability, together with three-electron-redox properties leading to high capacity3. However, research efforts over the past 30 years have encountered numerous problems, such as cathode material disintegratIon4, low cell discharge voltage (about 0.55 volts; ref. 5), capacitive behaviour without discharge voltage plateaus (1.1–0.2 volts6 or 1.8–0.8 volts7) and insufficient cycle life (less than 100 cycles) with rapid capacity decay (by 26–85 per cent over 100 cycles)4,5,6,7. Here we present a rechargeable Aluminium battery with high-rate capability that uses an Aluminium metal anode and a three-dimensIonal graphitic-foam cathode. The battery operates through the electrochemical depositIon and dissolutIon of Aluminium at the anode, and intercalatIon/de-intercalatIon of chloroaluminate anIons in the graphite, using a non-flammable Ionic liquid electrolyte. The cell exhibits well-defined discharge voltage plateaus near 2 volts, a specific capacity of about 70 mA h g–1 and a Coulombic efficiency of approximately 98 per cent. The cathode was found to enable fast anIon diffusIon and intercalatIon, affording charging times of around one minute with a current density of ~4,000 mA g–1 (equivalent to ~3,000 W kg–1), and to withstand more than 7,500 cycles without capacity decay.

  • First Principle Study on Atomic Scale Structures of Cathode in Aluminium-Ion Battery Using Various van der Waals CorrectIons
    'EDP Sciences', 2020
    Co-Authors: Kaihao Geng, Haining Cao, Mengchang Lin
    Abstract:

    There is still controversy on the atomistic configuratIon of Aluminium-Ion batteries (AIB) cathode when using first principle calculatIon based on density functIonal theory (DFT). We examined the relevant cathodic structures of Al/graphite battery by employing several van der Waals (vdW) correctIons. Among them, DFT-TS method was determined to be a better dispersIon correctIon in correctly rendering structural features already found through experiment investigatIons. The systematic comparison paved the way to the choice of vdW parameters in first principle calculatIon of graphitic electrode

  • A new cathode material for super-valent battery based on Aluminium Ion intercalatIon and deintercalatIon
    Scientific Reports, 2013
    Co-Authors: Wei Wang, Weiyi Xiong, Jungang Hou, Zheshuai Lin, Hongmin Zhu, Liwen Hu, Jiguo Tu, He Sun, Bo Jiang, Shuqiang Jiao
    Abstract:

    Due to their small footprint and flexible siting, rechargeable batteries are attractive for energy storage systems. A super-valent battery based on Aluminium Ion intercalatIon and deintercalatIon is proposed in this work with VO2 as cathode and high-purity Al foil as anode. First-principles calculatIons are also employed to theoretically investigate the crystal structure change and the insertIon-extractIon mechanism of Al Ions in the super-valent battery. Long cycle life, low cost and good capacity are achieved in this battery system. At the current density of 50 mAg(-1), the discharge capacity remains 116 mAhg(-1) after 100 cycles. Comparing to monovalent Li-Ion battery, the super-valent battery has the potential to deliver more charges and gain higher specific capacity.
