Researchers at the Korea Advanced Institute of Science and Technology have developed a nanoscale electrode design that could enhance anode-free electric vehicle batteries by addressing uneven lithium deposition. The technique involves creating tube-shaped structures on copper foil using secondary sputtering lithography and adding a 10-nanometer MXene coating, which together prevent dendrite formation and stabilize lithium deposition.
