Technical FAQs 3

What is a rechargeable potassium oxygen (k-o2) battery?

In particular, the rechargeable potassium oxygen (K-O2) battery has been recognized as a promising energy storage technology because of its low overpotential and high round-trip efficiency based on the single-electron redox chemistry of potassium superoxide.

Are potassium-based rechargeable batteries a solution to a global Li depletion crisis?

Online ahead of print. To mitigate a global crisis of Li depletion, potassium-based rechargeable batteries have received significant attention because of their low cost and high specific energy density.

Does oxygen contribute to battery storage capacity?

The role of oxygen has traditionally been assumed to be simply that of a spectator. But scientists have recently realized that oxygen can actively contribute to the battery’s storage capacity.
