Abstract

A novel hybrid battery utilizing an aluminum anode, a LiFePO₄ cathode and an acidic ionic liquid electrolyte based on 1-ethyl-3-methylimidazolium chloride (EMImCl) and aluminum trichloride (AlCl₃) (EMImCl–AlCl₃, 1–1.1 in molar ratio) with or without LiAlCl₄ is proposed. The hybrid ion battery delivers an initial high capacity of 160 mA h g⁻¹ at a current rate of C/5. It also shows good rate capability and cycling performance.
