Researchers develop 'world's first' potassium-packed battery with breakthrough design: 'Superior cycle life and excellent discharge capability'

"We are excited to introduce the world's first 18650 potassium-ion battery," Alexander Girau, CEO of Austin-based Group1, said in the report. The writeup went on to explain that "the 18650 form factor is the most widely used and designed cell formats."

The innovation promises some big wins, including being free of cobalt, nickel, copper, and lithium. These costly materials, common in batteries that power our electric vehicles and other devices, are often subject to complicated foreign supply chains.

Better yet, Group1 touts its tech as a superior option to emerging lithium-iron phosphate and sodium-ion batteries. The former type is being developed by Volvo's parent company, Geely, among others. The advantages of the potassium version include improved safety and higher energy storage, all per Group1's website.

The battery maker's leaders unveiled the invention during the Beyond Lithium-Ion Conference at Oak Ridge National Laboratory in July. Visitors learned how Group1 developed the battery from a coin-cell pack to a cylinder battery type that is common in most electronics, according to the release.
