Brookhaven researchers describe benefits of electrolyte additive

A team led by researchers at DOE’s Brookhaven National Laboratory has investigated the benefits of a lithium difluorophosphate additive for electrolytes in lithium batteries with nickel-rich layered cathodes. According to Brookhaven, the possibility of high-energy-density cells composed of nickel-rich layered cathodes and lithium metal anodes is limited by processes that reduce their capacity. In an… Read more »

Researchers develop method for stabilizing interfaces in solid-state batteries

Researchers at MIT and the DOE’s Brookhaven National Laboratory have developed a method for stabilizing the interfaces between the electrolyte and cathodes in solid-state batteries during the sintering process. Based on research reported in Advanced Energy Materials, the team found that when temperatures are above a few hundred degrees Celsius, carbon dioxide and reactions unfold… Read more »

Brookhaven researchers discover new approach to stabilizing high-nickel cathodes

High-nickel-content cathodes have captured the imagination of scientists, as they could enable much higher energy density. However, the high nickel content causes these cathode materials to degrade more quickly, creating cracks and stability issues as the battery cycles. A team of researchers at the DOE’s Brookhaven National Laboratory investigated the valence gradient of cathode materials… Read more »

Toyota researchers work with Brookhaven National Lab to investigate magnesium batteries

Toyota researchers are collaborating with the Center for Functional Nanomaterials (CFN) at the DOE’s Brookhaven National Laboratory to probe molecular structures and track chemical reactions in magnesium batteries. “Issues related to cost, power, energy density, and durability of Li-ion batteries have slowed their implementation in large-scale applications, such as electric and hybrid vehicles,” said Toyota… Read more »
