This research provides valuable insights into the use of electrolyte additives and promotes the long-term stability of AZIBs even at ultra-high current densities. The TFA electrolyte also enables Zn//5,7,12,14-pentacenetetrone full cells and Zn//active carbon capacitors to perform steadily for 10 000 cycles at 25 ☌ and 70 ☌, respectively.

As a result, Zn//Zn symmetric cells with the TFA electrolyte remain stable for over 1360 h and 800 h at high current densities of 5 mA cm −2 and 40 mA cm −2, respectively. H 2O and ZnF 2, forming a robust SEI that results in uniform Zn 2+ deposition and improved Zn 2+ transport kinetics.Moreover, TFA, with a low LUMO value, breaks down into Zn 4CO 3(OH) 6 The interaction between TFA and H 2O disrupts the H bond network structure of H 2O, resulting in a reduction of active H 2O and stabilization of the electrolyte's pH value. The CO group of TFA interacts strongly with Zn 2+, leading to a change in the inherent structure of Zn(H 2O) 6 2+ and an enhancement in the transport of Zn 2+. Herein, we propose a solution to the issue of AZIBs by creating a versatile electrolyte through the addition of trifluoroacetamide (TFA).

The practical application of aqueous zinc-ion batteries (AZIBs) is limited due to the inherent side reactions and dendrite growth of Zn anodes.
