Researchers at MIT are focusing on squeezing more energy out of non-rechargeable batteries. Here's how.
When an object like a lightbulb is placed along that circuit, the electrons are forced to move through it before moving on to the anode. But none of this can work without the medium of the electrolyte. And primary batteries don’t work forever.
“Now we have more of the mass of the battery actually being used for energy conversion,” says Betar Gallant, associate professor of mechanical engineering at MIT. Extending the life of high-energy primary batteries could be beneficial in many contexts where rechargeable batteries aren’t an option, and not just in pacemakers. “We’re also considering applying this to unmanned vehicles, defense applications, tracking for cargo, and space exploration,” says Gao.
