Three new kinds of battery that just might change the world (feat. Battery Lab Manager Greg Less)
So, it’s time to ask again: Why aren’t we all driving around in oxygen-powered cars? Well, the chemical reaction that produces energy in these batteries also happens to come with a considerable drawback. As it interacts with the oxygen, the aluminum degrades over time. It’s a type of battery called a “primary” cell, which means current only flows one way, from the anode to the cathode. That means they can’t be recharged. Instead, the batteries have to be swapped out and recycled after running down.
Electricity for rainforest villages in Gabon. Tent fabric that harvests solar energy for nomadic people in Kazakhstan. A modular greenhouse and fish farm in an unused industrial building in Highland Park, Michigan.
These are some of the goals and possibilities a team of 17 researchers will pursue with a new $3 million Third Century Initiative Global Challenges grant from the University of Michigan.
