Research output: NRELFact Sheet


Advancements in high capacity and low density battery technologies have led to a growing need for battery materials with greater charge capacity and therefore stability. NREL's developments in ALD and molecular layer MLD allow for thin film coatings to battery composite electrodes, which can improve battery lifespan, high charge capacity, and stability. Silicon, one of the best high-energy anode materials for Li-ion batteries, can experience capacity fade from volumetric expansion. Using MLD to examine how surface modification could stabilize silicon anode material in Li-ion batteries, researchers discovered a new reaction precursor that leads to a flexible surface coating that accommodates volumetric expansion of silicon electrodes.
