Light Enables Fast Charging of Lithium-Ion Batteries

Posted by MSE Supplies Admin on

Scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory have uncovered a new way to increase the speed of charging electric vehicles.  When the battery cathode in the electric vehicle is exposed to concentrated light, the overall charging time is reduced by at least a factor of two.  This phenomenon occurs due to the interaction between light and the material of the tested cathode, lithium manganese oxide or LiMn2O4 (LMO).  The manganese in the cathode absorbs photons of light, increasing its charge state from trivalent (Mn3+) to tetravalent (Mn4+), which then results in the ejection of lithium ions...

Source of Detrimental Dendrite Growth in Lithium Batteries Discovered

Posted by MSE Supplies Admin on

Scientists at the Pacific Northwest National Laboratory (PNNL) led by Chongmin Wang have conducted studies in order to understand the catastrophic growth of dendrites within lithium batteries.  Dendrites are structures that grow in the battery’s internal architecture and cause harm by breaking the barrier between the electrolyte and the lithium, which leads to battery failure.  The perpetrator of this phenomenon has been identified as ethylene carbonate.  Ironically, it is a solvent that is currently added to the electrolyte to improve battery performance.  Now that the root cause of these destructive dendrites has been identified, steps can be taken to not...

New Argonne Battery Design Offers "Solid" Advantage - Dopant‐Dependent Stability of Garnet Solid Electrolyte Interfaces with Lithium Metal

Posted by MSE Supplies Admin on

Credit: Argonne National Laboratory/Sanja Tepavcevic This multi-module ultrahigh vacuum system (in blue) allowed Argonne researchers to create and probe the interface of a solid electrolyte with a lithium metal anode without air exposure. This experiment correlated interfacial chemistry with the electrochemical response of the system. Most lithium batteries today consist of a liquid sandwiched between two solid materials. That conventional paradigm may be about to get some competition, however, as scientists have begun to investigate batteries that consist of all solid materials. Solid-state lithium batteries offer several advantages over those that use a liquid electrolyte; most notably, they allow for...
