A redesign for zinc-air batteries could make them rechargeable

Zinc-air batteries have a lot going for them. They’re lightweight, compact and made of more sustainable, less flammable materials than other batteries. But they’re usually not rechargeable. A new battery design could change that. By tweaking the building materials, researchers created a prototype of a zinc-air battery that could be recharged hundreds of times. Such […]

New class of cobalt-free cathodes could enhance energy density of next-gen lithium-ion batteries — ScienceDaily

Oak Ridge National Laboratory researchers have developed a new family of cathodes with the potential to replace the costly cobalt-based cathodes typically found in today’s lithium-ion batteries that power electric vehicles and consumer electronics. The new class called NFA, which stands for nickel-, iron- and aluminum-based cathode, is a derivative of lithium nickelate and can […]
