ABSTRACT
The overall performance of dual-ion batteries (DIBs) is strongly linked to anions storage properties of cathodes. Whereas high energy/power densities and stabilities for DIBs are limited by cathodes. To overcome these barriers, we have designed a novel fluoridized-polyaniline-H+ /carbon nanotubes (FPHC) as cathode for high-efficiency PF6 - storage. F- in PF6 - is easy to form covalent bond with H on -NH- in FPHC, so that PF6 - can stably coordinate with FPHC, showing a symmetrical structure. FPHC cathode shows a highly reversible capacity of 73 mAh g-1 at 2 A g-1 after 2000 cycles, which provides a solid base for the advanced sodium dual-ion batteries (SDIBs) (310 Wh kg-1 /7720 W kg-1 ). Besides, the relative pouch-type SDIB can drive a vacuum cleaner model with an electric machine. This work may shed light on an up-and-coming strategy of robust cathodes for SDIBs.
