Potassium ion energy storage

Recently, devices relying on potassium ions as charge carriers have attracted wide attention as alternative energy storage systems due to the high abundance of potassium resources (1.5 wt % in the earth's crust) and fast ion transport kinetics of K + in electrolyte. 1 Currently, owing to the lower standard hydrogen potential of potassium (−2.93 V vs. E0) compared to sodium (−2.71 V vs. E0), potassium ion batteries (PIBs) feature the advantage of high energy density have attracted great interest as an alternative to lithium-ion batteries (LIBs). 2 In addition to PIBs, extended potassium-ion storage systems such as dual-ion batteries and K−X (X=O 2, 3 I 2, 4 S, 5 Se 6) batteries have been reported and exhibited excellent K + -storage rate capability.

FAQS about Potassium ion energy storage

How do potassium ion batteries store energy?

The popularly reported energy storage mechanisms of potassium-ion batteries (PIBs) are based on alloy-, de-intercalation-, and conversion-type processes, which inevitably lead to structural damage of the electrodes caused by intercalation/de-intercalation of K + with a relatively large radius, which is accompanied by poor cycle stabilities.

Are potassium-ion batteries a viable technology for large scale energy storage?

Nature Communications 11, Article number: 1225 (2020) Cite this article Potassium-ion batteries are a compelling technology for large scale energy storage due to their low-cost and good rate performance. However, the development of potassium-ion batteries remains in its infancy, mainly hindered by the lack of suitable cathode materials.

Are potassium ions a charge carrier?

Tremendous progress has been made in the field of electrochemical energy storage devices that rely on potassium-ions as charge carriers due to their abundant resources and excellent ion transport properties.

Are advanced carbon materials suitable for potassium ion storage?

In the past few decades, advanced carbon materials have attracted great interest due to their low cost, high selectivity, and structural suitability and have been widely investigated as functional materials for potassium-ion storage.

Can high-temperature potassium-ion batteries have high cycle stability?

Distinctively different from the popularly reported works, an energy storage mechanism is proposed for exploring robust high-temperature potassium-ion batteries (PIBs) with high cycle stability. This is based on an example of p-phthalic acid with two carboxyl functional groups as the redox centers.

What is a potassium ion battery?

Science Potassium-ion batteries (PIBs) have attracted tremendous attention due to their low cost, fast ionic conductivity in electrolyte, and high operating voltage. Research on PIBs is still in its infanc...
