{"url":"/dataset/ieis","name":"IEIs","full_name":"Ion and Electron Insulators","description_markdown":"We would like to introduce three types of _ion and electron insulators_, i.e. _Li-ion & electron insulators_ (LEIs), _Na-ion & electron insulators_ (NEIs), and _K-ion & electron insulators_ (KEIs), and provide a set of codes here to screen candidate materials from computational material database, [Materials Project](https://materialsproject.org/). The IEI materials are able to block the transport of multiple charge carriers (ions and electrons) and stay thermodynamically stable against specific alkali-metals. The screening workflows and usage of IEI materials in rechargeable solid-state Li/Na/K metal batteries are presented in the paper below.","description_withheld":null,"homepage":"https://doi.org/10.5281/zenodo.4548804","introduced_date":"2021-08-17","introduced_date_note":null,"introduced_by":null,"license":{"name":"MIT License","url":"https://opensource.org/licenses/MIT"},"modalities":[{"name":"Tabular","url":"/datasets/modality/tabular"}],"tasks":[],"languages":[{"name":"English","url":"/datasets/language/english"}],"variants":["IEIs"],"data_loaders":[],"num_papers_in_archive":1,"source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28"},"benchmarks":[],"papers_with_a_benchmark_row":[],"syntology_totals":{"read_at":"2026-09-24T18:15:14+00:00","papers_with_samples":0,"samples_harvested":0,"samples_ran":0,"samples_unverified":0,"pointer_only_for_licence":0,"papers_with_no_sample_that_ran":0,"note":"the per-paper counts above, summed; not a rate"},"papers_note":"The archive never published its papers-using-dataset list; these are papers with a leaderboard row on this dataset's benchmarks."}
