Remember the banana art ?

Hearing a lot about lithium still, but what about the potassium ion battery?
— research by Tsinghua University, among others like Korea University

“…life on the planet is somehow based on biological potassium-ion batteries. K+ is the key charge carrier in plants. Circulation of K+ ions facilitates the energy storage in plants by forming decentralized potassium batteries.”—Wiki

In Humans: “Potassium plays an important role in cell membrane physiology, especially in maintaining resting membrane potential and in generating action potentials in the nervous system and heart.” —Science Direct
