SnS2 quantum dots-coated VO2@carbon nanorods for secondary battery displaying high capacity and rate-performance

A VO 2 @carbon@SnS 2 composing of SnS 2 quantum dots coating on lamellar VO 2 @carbon is developed as an Al-ion battery cathode. Upon cycling 1000 times at 1.0 A g −1 , the cathode remains stable, and a recoverable rate-performance is achieved.
