Real-Time Detection of Lithium Plating During Fast Charge of Lithium Ion Batteries
Fast charging of lithium ion batteries is a critical enabler for mass EV adoption. Sandia National Laboratories (SNL) has been working with the University of Michigan to develop graphite anodes with novel 3D structures that facilitate faster charging while avoiding lithium plating, a main danger of unaided fast charging. SNL is using its unique high precision cycling capability, developed through ARPA-E funding, to characterize the ability of improved anodes to withstand fast charge and resist lithium plating, and the danger of lithium plating in present-day batteries.
