How the electrodes of lithium-air batteries become passivated

Lithium-air batteries produce power from air, and are often called lithium-oxygen batteries. They are much lighter than lithium-ion batteries due to higher energy density. Lithium-air batteries have applications including ...

Battery breakthrough using 2016 Nobel Prize molecule

Silicon anodes are receiving a great deal of attention from the battery community. They can deliver around three to five times higher capacity compared with those using current graphite anodes in lithium ion batteries. A ...

Study suggests route to improving rechargeable lithium batteries

Most of today's lithium-ion batteries, which power everything from cars to phones, use a liquid as the electrolyte between two electrodes. Using a solid electrolyte instead could offer major advantages for both safety and ...

How some battery materials expand without cracking

When you charge a battery, or when you use it, it's not just electricity but also matter that moves around inside. Ions, which are atoms or molecules that have an electric charge, travel from one of the battery's electrodes ...

Lighter, more efficient, safer lithium-ion batteries

Researchers from Universidad Carlos III de Madrid and the Council for Scientific Research (initialed CSIC in Spanish) have patented a method for making new ceramic electrodes for lithium-ion batteries that are more efficient, ...

Team develops sustainable, high energy density battery

Researchers at The City College of New York-based CUNY Energy Institute announce the development of a novel low cost, rechargeable, high energy density battery that makes the widespread use of solar and wind power possible ...
