Lithium-air (Li-air) technology, an ambitious next-generation battery design, has been a story full of promises and difficult challenges. In theory, Li-air designs allow for the highest specific energy, enabling much improved battery capacities and leading to goals like IBM’s 500 mile electric vehicle battery project. However, Li-air also has issues like cycle life and volumetric inefficiency. In the face of these Li-air obstacles, developers are now pivoting in different ways as they search for the next big thing in energy storage.
