82We present a data-driven platform for exploring next-generation battery materials. At its core is the AtomWork Battery database, which compiles material data from over 1,000 selected papers on solid electrolytes and cathode materials. This data includes key properties such as chemical composition, crystal structure, ionic conductivity, and charge/discharge capacity. Additionally, we have developed a Python package, AtomWork Creator, designed for the exploration of superionic conductors. This package features tools for descriptor encoding/decoding, ionic conductivity prediction, and material design, leveraging the data from the AtomWork Battery database. This integrated approach accelerates the exploration of new superionic conductors and provides a continuously updated, comprehensive resource to advance battery material development through data-driven methods. This work was supported by JST COI-NEXT “Center for Advanced Battery Collaboration” Grant Number Phosphor materials that use Eu2+ ions as the luminescent center utilize luminescence that accompanies electron transitions from 5d orbitals to 4f orbitals. As 5d orbitals are strongly affected by the host lattice, luminescence properties change greatly depending on the host. For example, the emission color changes from near-infrared to near-ultraviolet depending on the host. To rapidly develop phosphor materials for specific applications, it is necessary to design and search for host compounds that meet various requirements for phosphors. In this paper, we introduce the exploration of novel Eu2+-activated phosphor materials using a data-driven approach.
