A new paper presents a stable lithium-metal battery design for the first time. Lithium-ion batteries have flaws that lithium-metal batteries could fix. This new battery adds a self-healing technology that will close cracks where dendrites form. Lithium-ion batteries are the backbone of most of today’s electronic devices, including electric vehicles. But for all of their game-changing benefits, the batteries still have an inherent flaw: dendrites. These thin, snaking, tree-like pieces of lithium form sharp points and end up piercing the battery, causing short circuits and other problems. This ultimately shortens the lifespan of lithium-ion batteries, and leaves major room for...

Credit: Ji et al. ______________________________________________________________________________ In recent years, lithium-based batteries have become widely used to power a wide range of electronic devices, including tablets, smart phones and portable computers. These batteries have different compartments, called cells, each of which contains a positive electrode and a negative electrode separated by a chemical known as an electrolyte. Positive electrodes are generally composed of lithium compounds, such as LiCoO2 or LiFePO4, while negative electrodes are usually made of carbon. The electrolyte separating them, on the other hand, can...

Researchers have been in a race to find ways to improve lithium-ion batteries. They are also looking to develop alternatives to the lithium-ion battery that would be lower cost and more sustainable to manufacture. And they may just have found one. Aluminum-based batteries would be cheaper to make, because aluminum is the third most abundant element in the Earth’s crust after oxygen and silicon. Aluminum is also light-weight and could be ideal for use in batteries.
