Long life exceeding 10 000 cycles for aluminum-ion batteries based on an FeTe2@GO composite as the cathode

Abstract

A nanocomposite consisting of iron telluride wrapped with graphene oxide (GO) was prepared via a hydrothermal method. As the cathode material for aluminum-ion batteries (AIBs), it exhibited a remarkable long-term cycle performance with a reversible capacity of 120.4 mA h g−1 at 1 A g−1 after 10 000 cycles, i.e., a cyclability better than those of all other transition metal chalcogenides in AIBs reported to date. Furthermore, an energy storage mechanism, involving the intercalation and deintercalation of multiple ions (AlCl4, Cl and Al3+), was elucidated. This study offers guidance for further development of transition metal tellurides for AIBs.
