Researchers now able to predict battery lifetimes with machine learning

Technique could reduce costs of battery development

10-May-2022

Imagine a psychic telling your parents, on the day you were born, how long you would live. A similar experience is possible for battery chemists who are using new computational models to calculate battery lifetimes based on as little as a single cycle of experimental data. In a new study, ...

New electrolyte for solid-state lithium-ion batteries

New battery material offers promise for the development of all-solid batteries

18-Feb-2022

In the quest for the perfect battery, scientists have two primary goals: create a device that can store a great deal of energy and do it safely. Many batteries contain liquid electrolytes, which are potentially flammable. As a result, solid-state lithium-ion batteries, which consist of entirely ...

Why batteries can’t charge in minutes

Researchers find new issue complicating fast charging

06-Dec-2021

Researchers find new issue complicating fast charging. Haste makes waste, as the saying goes. Such a maxim may be especially true of batteries, thanks to a new study that seeks to identify the reasons that cause the performance of fast charged lithium-ion batteries to degrade in electric ...

Turning carbon dioxide into liquid fuel

New electrocatalyst efficiently converts carbon dioxide into ethanol

07-Aug-2020

Catalysts speed up chemical reactions and form the backbone of many industrial processes. For example, they are essential in transforming heavy oil into gasoline or jet fuel. Today, catalysts are involved in over 80 percent of all manufactured products. A research team, led by the U.S. Department ...
