Graphene Nanoplatelet Composite Cathode for a Chloroaluminate Ionic Liquid-Based Aluminum Secondary Battery
Source abstract
Abstract
The development of an aluminum secondary battery based on an Al metal anode, a graphene nanoplatelet composite cathode, and a Lewis acidic AlCl3–1-ethyl-3-methylimidazolium chloride ionic liquid electrolyte is demonstrated. Low-cost composite cathodes comprising only commercially available components are prepared by a standard slurry-coating method, and the cathodes exhibit a reversible capacity reaching 70 mAh g–1 (per graphene nanoplatelet weight) at a current density of 2000 mA g–1 and a good rate capability (∼66% capacity retention at 6000 mA g–1). A notable cyclability of up to 3000 cycles with a Coulombic efficiency approaching 99% is also obtained at 2000 mA g–1.
