Mix of quick and conventional charging protects the battery

Interference-free charging is a major prerequisite for the economically efficient use of electric vehicles. After about 120,000 km driven electrically, the RheinMobil project has proved that a combination of quick and conventional ...

Researchers develop methods to study battery chemistry in action

Researchers at a host of national laboratories and universities have developed a way to microscopically view battery electrodes while they are bathed in wet electrolytes, mimicking realistic conditions inside actual batteries. ...

Batteries as they are meant to be seen

Researchers have developed a way to microscopically view battery electrodes while they are bathed in wet electrolytes, mimicking realistic conditions inside actual batteries. While life sciences researchers regularly use ...

Why lithium-ion-batteries fail

Materials in lithium ion battery electrodes expand and contract during charge and discharge. These volume changes drive particle fracture, which shortens battery lifetime. A group of ETH scientists together with colleagues ...

For better batteries, just add water

Lithium-ion batteries are now found everywhere in devices such as cellular phones and laptop computers, where they perform well. In automotive applications, however, engineers face the challenge of squeezing enough lithium-ion ...

Nanoparticles improve lithium battery electrodes

(Phys.org)—Materials scientists have developed a simple, robust way to fabricate carbon-free and polymer-free, lightweight colloidal films for lithium-ion battery electrodes, which could greatly improve battery performance.

US firm bars lead at China plant after poison claims

US battery giant Johnson Controls will stop lead processing at a plant in China's commercial hub Shanghai, the firm said, after the city found high levels of the metal in children living nearby.

Charging up the auto industry

This year's iconic North American International Auto Show featured a wave of new hybrid and electric cars that suggest the vehicles have truly come into their own. But what's the future for the technology needed to power ...
