Measuring the process in unprecedented detail gave them clues to how to minimize the problem and protect battery performance. The results could suggest a fix. When lithium ions […]

A Purdue University scientists led a multi-institute team of researchers has developed the most comprehensive view yet of lithium-ion battery electrodes. The electrodes are where most damage typically occurs from charging them repeatedly. The researchers say manufacturers could use this information to design batteries for your smartphone or car that are both more reliable and […]

Brookhaven National Laboratory scientists have synthesized a new cathode material from iron fluoride that surpasses the capacity limits of traditional lithium-ion batteries. Scientists are searching for ways to improve lithium-ion batteries, the most common type of battery found in home electronics and a promising solution for grid-scale energy storage. Increasing the energy density of lithium-ion […]

Brookhaven National Laboratory scientists have observed an unexpected phenomenon in lithium-ion batteries – the most common type of battery used to power cell phones and electric cars. As a model battery generated electric current, the scientists witnessed the concentration of lithium inside individual nanoparticles reverse at a certain point, instead of constantly increasing. This discovery, […]

Researchers at the Department of Energy’s Pacific Northwest National Laboratory (PNNL) have developed a way to microscopically view battery electrodes while they are bathed in wet electrolytes, mimicking realistic conditions inside actual batteries. The research was published in the December 11’s issue of Nano Letters.  The techniques are good news for scientists studying battery materials […]
