Re: Lithium used for batteries

World’s first 18650 Potassium-ion battery debuts, can replace lithium cells

An 18650 potassium-ion battery represents a category of rechargeable batteries that employs potassium ions as the charge carrier, in contrast to the more prevalent lithium ions.

This type of battery possesses the same form factor as the commonly utilized 18650 lithium-ion battery, with a diameter of 18 mm and a length of 65 mm.

The battery operates at a nominal voltage of 3.7V, thus guaranteeing compatibility with contemporary electronic devices and systems.

Moreover, it has exhibited a clear trajectory toward achieving a gravimetric energy density of 160-180Wh/kg, which is on par with lithium iron phosphate lithium-ion batteries (LFP-LIB).

It can be a compelling substitute for both lithium-ion batteries based on LiFePO4 (LFP) and sodium-ion batteries (NIBs), which have encountered difficulties related to cost and effectiveness.
