Abstract Scope |
The increasing demand for lithium-ion batteries has posed a significant challenge in terms of lithium and cobalt availability and their costs. Aluminum-ion batteries are among post lithium-ion batteries that have gained significant interests because of outstanding properties of aluminum including low cost, high abundance, and high theoretical capacity. Most aluminum batteries utilize expensive and corrosive alkylimidazolium/pyridinium chloride-based chloroaluminate ionic liquids with limited widespread applicability. Here, we report a high-performance aluminum battery made of aluminum anode, graphene nanoplatelets cathode, and low-cost aluminum chloride-trimethylamine hydrochloride ionic liquid electrolyte. The battery operates in the temperature range of –10 to 60 ℃ and delivers a capacity of 134 mAh g−1 at 2000 mA g–1 while maintaining a Coulombic efficiency above 98% over 3000 cycles at room temperature. We predict that our battery will help realize the technological potential of aluminum ion batteries by addressing some critical aspects of performance and cost. |
