Organic Battery Breakthrough
A new discovery by a team of chemists has just shined a light on the possibility of highly efficient organic batteries taking the place of the current toxic and inefficient batteries currently in use.
Research by a team of University of Texas at Austin chemists led by Christopher Bielawski and Jonathan Sessler was published in Science. The scientists figured out how to get molecules to transfer their electrons back and forth in a way that had never been done before. “These molecules were effectively spring-loaded to push apart after interacting with each other,” explained Bielawski. “After electron transfer occurs, two positively charged molecules are formed which are repelled by each other, much like magnets held in a certain way will repel each other. We also installed a chemical switch that allowed the electron transfer process to proceed in the opposite direction.” “I would love it if my iPhone was thinner and lighter, and the battery lasted a month or even a week instead of a day,” said Bielawski. “With an organic battery, it may be possible. We are now starting to get a handle on the fundamental chemistry needed to make this dream a commercial reality.” “This is the first time that the forward and backward switching of electron flow has been accomplished via a switching process at the molecular scale,” added Sessler.
