New negative electrode materials for zinc ion batteries

Do zinc-ion battery electrolytes affect the cathode interface?

Current state of research on zinc-ion battery electrolytes and their effect on the cathode interface Electrolyte is an essential component of a battery, serving as the medium for connecting the positive and negative electrodes and facilitating ion transfer.

What is the electrode/electrolyte interface of aqueous zinc-ion battery systems?

However, studies on the electrode/electrolyte interface of aqueous zinc-ion battery systems have primarily focused on the surface of the zinc anode. This has been achieved through the construction of SEIs or the design of interfacial membranes with a uniform electric field and induced deposition to stabilize the zinc anode.

Can zinc negative electrodes be used as ZIB anodes?

These properties make them ideal for use as ZIB anodes with high speed performance and ruggedness . In summary, it is evident that the design of the zinc negative electrode can be improved through structural modifications, coatings, and electrolytes to mitigate issues such as zinc dendrites, passivation, and self-precipitation of hydrogen.

How to improve battery performance by modifying the zinc electrode?

Research on improving battery performance by modifying the zinc electrode can be based on three major directions: Improving the structure of the zinc electrode by using functional materials or materials with porous or layered structures; adding additives to the electrolyte to optimize the structure or morphology of the electrode; and zinc alloying.

Should aqueous zinc-ion batteries be used for electrical storage?

Aqueous zinc-ion batteries (AZIBs) have emerged as a practically attractive option for electrical storage because of environmentally benign aqueous-based electrolytes, high theoretical capacity of Zn anode, and significant global reserves of Zn. However, application of AZIBs at the grid-scale is restricted by drawbacks in cathode material (s).

Why do zinc ion batteries have a low voltage?

Due to the narrow thermodynamic stability window of water, the voltage of zinc-ion batteries is limited, and their charging and discharging processes are always coupled with the occurrence of side reactions such as hydrogen and oxygen precipitation.
