Aqueous metal ion battery: next-generation energy storage solution

Aqueous metal ion battery: next-generation energy storage solution

Aqueous metal ion batteries, exemplified by zinc-ion batteries, leverage zinc ions as charge carriers in an aqueous electrolyte solution.

These batteries present advantages over traditional lithium-ion counterparts including:

  • cost-effectiveness due to the abundance and lower cost of zinc

  • enhanced safety with the use of aqueous electrolytes

  • high zinc solubility facilitating efficient ion transport

  • environmental friendliness due to recyclable zinc components 

  • scalability for large-scale energy storage applications

  • A potentially long cycle life.

While these batteries face challenges such as energy density limitations, this research aims to address these issues and further optimise the performance of aqueous metal ion batteries for diverse energy storage needs.
