sodium ion
The sodium ion is a chemical species celebrated as the poster child of resource efficiency and sustainability, yet often exploited as the latest corporate buzzword. Dragged from mines to cut costs, it endures a relentless cycle of insertion and extraction within batteries. Marketed as an eco-hero to save our future, it frequently ends up as the tragic protagonist, screaming in a short-lived supporting role. The very vehicle meant to protect the planet is ultimately abandoned alongside your dead phone battery.
