Are potassium ion batteries a good alternative?

Potassium-ion batteries (PIBs) are at the top of the list of alternatives because of the abundant raw materials and relatively high energy density, fast ion transport kinetics in the electrolyte, and low cost.

What are the advantages of potassium ion battery?

The advantage of potassium ion battery is that high-priced raw materials such as lithium, cobalt, and copper used in lithium-ion batteries can be replaced with inexpensive and abundant raw materials such as potassium, iron, and aluminum. Moreover, potassium has less risk of fire than lithium and can also improve safety.

What is a potassium ion battery?

Potassium-ion batteries (PIBs) are at the top of the list of alternatives because of the abundant raw materials and relatively high energy density, Battery science and technology – powered by chemistry

Why is potassium ion battery different from other alkali metal ionic batteries?

In addition, because of the larger radius of potassium ion, the reactivity of metal potassium is higher, which leads to the great difference between the electrode material design and the manufacture of full battery of potassium ion battery and other alkali metal ion batteries.

Why do potassium ion batteries pulverize?

First, the larger K+ makes the volume expansion of the potassium ion battery more severe than other alkali metal ion batteries during the charge/discharge process, which leads to the collapse of the crystal structure of the electrode material and the pulverization of the electrode.

Why are rechargeable potassium batteries important?

This is because both the precursors and the inactive components in potassium are inexpensive. Importantly, rechargeable potassium batteries can gain insight from already-proven lithium-ion battery technologies in the course of future scientific study, development, and commercialization.
