Researchers at the DOE’s Pacific Northwest National Laboratory have discovered that the “special sauce” of batteries is all about the salt concentration. By getting the right amount of salt right where they want it, they’ve demonstrated that a lithium-metal battery can undergo about seven times more charge/discharge cycles than batteries with conventional electrolytes. Finding an electrolyte solution… Read more »

An international team of scientists, including researchers from the DOE’s Argonne National Laboratory, has discovered an anode material that enables super-fast charging and offers stable operation over many thousands of cycles. In a recent article in Nature Communications, Argonne Battery Scientist Jun Lu and colleagues describe a water-bearing compound, lithium titanate hydrate, that could replace… Read more »

Researchers at the Oak Ridge National Laboratory (ORNL) have developed a way to mitigate the risk of battery failure during automobile accidents by including slits along the electrodes. In “Limiting Internal Short-Circuit Damage by Electrode Partition for Impact-Tolerant Li-Ion Batteries,” published in the journal Joule, the research team explains how this technology could allow manufacturers… Read more »
