Axions are a hypothetical particle which can help solve the strong CP problem in quantum chromodynamics and could be a possible dark matter candidate. Axions could be produced by 7Li nuclei in the sun and due to doppler broadening these axions could then be detected on earth using a source containing 7Li. In this poster, we report the results of a search for 7Li solar axions with the CUPID-Mo experiment. CUPID-Mo is a neutrinoless double beta decay experiment using Lithium Molbydate (LMO) crystals operated as cryogenic calorimeters. Additionally, a large mass of 7Li available in detectors with very good energy resolution enables a sensitive search for axions. These results help close a gap in the excluded axion mass range from experiments using 57Fe/83Kr detectors, which is sensitive to smaller axion mass, and 7Li, sensitive to higher mass.
