Abstract

Abstract: Aluminum storage in rutile-based TiO2 nanoparticles was for the first time investigated. Electrochemical characteristics of rutile-based TiO2 nanoparticles as an electrode for aluminum-ion batteries were studied using cyclic voltammetry, chronopotentiometry and electrochemical impedance spectroscopy. The first discharge capacity of 29.4 mAh·g -1 was achieved, and the value remains 22.6 mAh·g -1 after 50 cycles. The highest coulombic efficiency achieved at 89.8%.
