New Battery Design Extends the Life of Low-Cost, Lightweight Batteries
New battery design could greatly extend the shelf life of single-use metal-air batteries for electric vehicles, off-grid storage, and other applications. Metal-air batteries are one of the lightest and most compact types of batteries available, but they can have a major limitation: When not in use, they degrade quickly, as corrosion eats away at their metal electrodes. Now, MIT researchers have found a way to substantially reduce that corrosion, making it possible for such batteries to have much longer shelf lives. While typical rechargeable lithium-ion batteries only lose about 5 percent of…
