When looking at the potential for cars, the battery could be used for EVs with super long ranges, but I don’t see that as the most practical use. Those modes of transportation need so much energy that battery packs have been impractical because of the substantial size and weight that would be needed. “It’s all about the chemistry and energy density,” he said about what makes this battery special.įor him, one of the most exciting aspects of this research is the potential to develop batteries for use in maritime transport and aviation. Mohammad Asadi, a chemical engineer at Illinois Tech, was another leader of the team that developed the battery and a co-author of the paper. That’s a lot, even when compared to other designs for solid state batteries, and it’s three to four times more than most current EVs. The real world implications of the technology are substantial, with the potential for batteries that could power an EV for 1,000 miles on a single charge. But the most likely answer is that the combination of materials results in an environment that cajoles the oxygen to have the four-electron reaction. So why are the oxygen molecules in this battery reacting with more electrons? It’s complicated, and the researchers are still in the process of answering that question. It’s a lot more efficient if you can carry four bags on each trip as opposed to one or two. Think of this like when you’re unloading a trunkful of grocery bags from the car. In this new battery, each oxygen molecule reacts with up to four electrons. To understand what makes this battery different, it helps to know that in previous lithium-air batteries each oxygen molecule would react with one or two electrons. The electrolyte is made from a combination of ceramic and polymer materials-a solid that still allows for the passage of ions. Oxygen from the air reacts with lithium ions that have passed through the solid electrolyte. The “air” part comes from outside air that flows in through tiny holes in the cathode. In this specific battery, the anode is made of a solid form of lithium. The design at Argonne and Illinois Tech is a version of a lithium-air battery, a category that has been around for about a decade but hasn’t yet had a commercial breakthrough.
