Tracking pileups on battery charging route to drive performance

Because of their high storage capacity, metal oxides are a promising class of potential conversion-type electrode materials for next-generation lithium-ion batteries. Conversion-type electrode materials undergo conversion ...

'Nanochains' could increase battery capacity, cut charging time

How long the battery of your phone or computer lasts depends on how many lithium ions can be stored in the battery's negative electrode material. If the battery runs out of these ions, it can't generate an electrical current ...

Cause of cathode degradation identified for nickel-rich materials

A team of scientists including researchers at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and SLAC National Accelerator Laboratory have identified the causes of degradation in a cathode material for ...

Chemists seek state-of-the-art lithium-sulfur batteries

When can we expect to drive the length of Germany in an electric car without having to top up the battery? Chemists at the NIM Cluster at LMU and at the University of Waterloo in Ontario, Canada, have now synthesized a new ...

For better li-ion batteries, scientists watch one at work

(Phys.org) —Using x-rays at the National Synchrotron Light Source (NSLS), a group of researchers has studied, in great detail, the nanoscale workings of a lithium-ion battery, learning new information about the chemical ...

Designer glue improves lithium-ion battery life

(Phys.org) —When it comes to improving the performance of lithium-ion batteries, no part should be overlooked – not even the glue that binds materials together in the cathode, researchers at SLAC and Stanford have found.

An environmentally friendly battery made from wood (Update)

Taking inspiration from trees, scientists have developed a battery made from a sliver of wood coated with tin that shows promise for becoming a tiny, long-lasting, efficient and environmentally friendly energy source. Their ...
