However, issues of dendrites and side reactions between zinc metal anode and the electrolyte need to be solved for extended storage and cycle life. Here, we proposed that an electrolyte additive with an intermediate chelation strength of zinc ion鈥攕trong enough to exclude water molecules from the...
An aqueous zinc-ion battery using the above-studied Mn(BTC) cathode and ZIF-8@Zn anode was constructed, as illustrated in Fig.7a. 2 M ZnSO4aqueous solution was chosen as the electrolyte. CV curves at a scan rate of 0.5 mV s−1are displayed in Fig.7b. It can be seen that there e...
Aqueous zinc-ion batteries (AZIBs) are considered a potential contender for energy storage systems and wearable devices due to their inherent safety, low cost, high theoretical capacity, and environmental friendliness. With the multi-scenario applications of AZIBs, the operation of AZIBs at extreme...
On the other hand, the reversibility of the zinc anode has a great influence on the cycling stability of the battery. Figure S15A compares the cycling stability of Zn||Zn symmetric cells in different electrolytes at 0.1 mA cm−2 current density with 1 mAh cm−2 capacity limit. The Zn...
Polyaniline (PANI), with merits of high electronic conductivity and capacity, is a promising material for zinc (Zn)-ion batteries. However, its redox window in Zn batteries is often limited, mainly due to the oxidative degradation at high potentials—in which imine groups can be attacked by ...

Fatal casualties resulting from explosions of electric vehicles and energy storage systems equipped with lithium-ion batteries have become increasingly common worldwide. As a result, interest in developing safer and more advanced battery systems has grow
Here we report a highly reversible zinc/sodium vanadate system, where sodium vanadate hydrate nanobelts serve as positive electrode and zinc sulfate aqueous solution with sodium sulfate additive is used as electrolyte. Different from conventional energy release/storage in zinc-ion batteries with only ...
The highly reversible zinc-bromine redox couple has been successfully applied in the zinc-bromine flow batteries; however, non-electroactive pump/pipe/reservoir parts and ion-selective membranes are essential to suppress the bromine diffusion. This work demonstrates a zinc-bromine static (non-flow) b...
Here, a natural and non-toxic inositol additive with six hydroxyl groups is added into the 2 M ZnSO4 aqueous baseline electrolyte to enhance the electrochemical performances of the zinc ion batteries. 2H chemical shift in the Nuclear magnetic resonance demonstrates that the inositol molecule exhibits...
