Valid design and evaluation of cathode and anode materials of aqueous zinc ion batteries with high-rate capability and cycle stability

The rate capability of the AVNF//Al2O3@Zn was 108 mAh g-1 even at 20 A g-1, by employing the sonochemical method, which is the fast and efficient synthesis. The Zn anode were coated by Al2O3 of 9.9 nm, and therefore, the initial capacity is maintained to 94 % after 5,000 cycles even at 10 A g-1.
