MIT Researchers Create Cheap 'Air-Breathing' Battery For Green Energy

By

In order to make renewable energy reliable on a large scale, there needs to be a way to store the power that's being generated. Batteries are the best solution, but lithium-ion can be a costly product and they lose capacity after every recharge. Researchers at the Massachusetts Institute of Technology have developed a more natural battery that’s not only reliable, but much less expensive.

This new battery is labeled as “air-breathing,” meaning that oxygen does push in and out of it to make it work. Sulfur dissolved in water is the anode (negative side) of the battery while a liquid salt solution represents the cathode (plus side). When oxygen moves into the battery, electrons are released from the anode.
