However, the growing concern on scarcity and large-scale applications of lithium resources have steered effort to realize sustainable sodium-ion batteries, \u200bNa and \u200bFe being abundant and low-cost charge carrier and redox centre, respectively. However, their performance is limited owing to low operating voltage and sluggish kinetics. Here we report a hitherto-unknown material with entirely new composition and structure with the first alluaudite-type sulphate framework, Na2Fe2(SO4)3, registering the highest-ever Fe3+/Fe2+ redox potential at 3.8\u2009V (versus \u200bNa, and hence 4.1\u2009V versus \u200bLi) along with fast rate kinetics. Rare-metal-free Na-ion rechargeable battery system compatible with the present Li-ion battery is now in realistic scope without sacrificing high energy density and high power, and paves way for discovery of new earth-abundant sustainable cathodes for large-scale batteries.", "subitem_description_type": "Abstract"}]}, "item_2_description_6": {"attribute_name": "\u5185\u5bb9\u8a18\u8ff0", "attribute_value_mlt": [{"subitem_description": "UTokyo Research\u63b2\u8f09\u300c\u65b0\u7269\u8cea\u767a\u898b\u3067\u96fb\u6c60\u306e\u30ec\u30a2\u30e1\u30bf\u30eb\u4f7f\u7528\u30bc\u30ed\u306b\u300d URI: http://www.u-tokyo.ac.jp/ja/utokyo-research/research-news/materials-discovery-for-earth-abundant-battery/", "subitem_description_type": "Other"}, {"subitem_description": "UTokyo Research \"Materials discovery for earth-abundant battery\" URI: http://www.u-tokyo.ac.jp/en/utokyo-research/research-news/materials-discovery-for-earth-abundant-battery/", "subitem_description_type": "Other"}]}, "item_2_publisher_20": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "Nature Publishing Group"}]}, "item_2_relation_11": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "info:doi/10.1038/ncomms5358", "subitem_relation_type_select": "DOI"}}]}, "item_2_relation_25": {"attribute_name": "\u95a2\u4fc2URI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "http://www.u-tokyo.ac.jp/ja/utokyo-research/research-news/materials-discovery-for-earth-abundant-battery/", "subitem_relation_type_select": "URI"}}, {"subitem_relation_type_id": {"subitem_relation_type_id_text": "http://www.u-tokyo.ac.jp/en/utokyo-research/research-news/materials-discovery-for-earth-abundant-battery/", "subitem_relation_type_select": "URI"}}, {"subitem_relation_type_id": {"subitem_relation_type_id_text": "http://www.nature.com/ncomms/2014/140717/ncomms5358/abs/ncomms5358.html", "subitem_relation_type_select": "URI"}}]}, "item_2_rights_12": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "(c) 2014 Macmillan Publishers Limited.
