Lithium ion movement inside nanoparticles could be key to faster-charging, longer-lasting batteries

By Faye Oney / January 16, 2018

By observing lithium ion movement in nanoparticles, researchers have discovered that instead of increasing, they reverse at a certain point. Their discovery could be a breakthrough in faster-charging and longer-lasting batteries.

3D graphene to replace platinum in dye-sensitized solar apps? Dye-sensitized solar cells are thin, flexible, easy to make, and efficient. However, they use platinum, and, at $1,500 an ounce, the cost of the precious metal is significant even in the small quantities used in dye-sensitized cells. Now researchers at Michigan Technological University, Houghton, have developed…

Light that moves and molds gels Researchers at the University of Pittsburgh have demonstrated a biomimetic response in hydrogels—a material that constitutes most contact lenses and microfluidic or fluid-controlled technologies. Their study, published in Advanced Functional Materials, is the first to show that these gels can be both reconfigured and controlled by light, undergoing self-sustained…

OSU group studies aging of Li-ion batteries

By / November 4, 2010

Ohio State University’s Center for Automotive Research is studying why batteries lose their ability to hold a charge as they age. In collaboration with ORNL and NIST, the group is focusing on lithium-ion batteries, which are hot in the electric car industry. Preliminary results from the ongoing study suggest that external conditions such as temperature…
