Finding novel solid-state ionic materials leads to innovative battery systems. \u00a0We explore and design novel solid-state ionic materials with sodium and magnesium as carrier ions to develop beyond lithium-ion batteries.\u00a0<\/p>\n<h2 id=\"2\">Low-temperature synthesis of complex metal oxides<\/h2>\n<p>Complex metal oxides are typically synthesized at a high temperature of &gt;1000 \u00b0C via the conventional solid-state reaction because metal ion diffusion in the solid phase requires high energy. We recently developed a new synthesis process named &#8220;hydroflux process, &#8221; enabling us to obtain the layered lithium cobalt oxide at 300 \u00b0C within 30 minutes. Understanding the phase stability and reaction pathway of complex metal oxides becomes essential knowledge for the development of effective synthetic processes.\u00a0<\/p>\n<h2 id=\"3\">Crystal growth mechanisms in less noble metal electrodeposition<\/h2>\n<p>Rechargeable batteries using the electrodeposition\/dissolution process of metals have never been successful in commercialization because of uneven electrodeposition of metals, leading to the short-circuit of the cell. We have been studying the crystal growth process of magnesium metal, which shows uniform surface morphology. We aim to understand the key factors determining the crystal growth process of less noble metals to control the surface morphologies. \u00a0<\/p>\n<p><\/p>\n<div class=\"row\">\n<div class=\"col-md-6\"><img decoding=\"async\" src=\"https:\/\/wwwchem.sci.hokudai.ac.jp\/~inorganic\/wp-content\/uploads\/2023\/06\/zu1.jpg\" class=\"full\" \/>\n<p><\/p>\n<p>Improved phase stability of P3 type layered cathode active materials for Na-ion battery via Ca substitution.<\/p>\n<\/div>\n<div class=\"col-md-6\"><img decoding=\"async\" src=\"https:\/\/wwwchem.sci.hokudai.ac.jp\/~inorganic\/wp-content\/uploads\/2023\/06\/zu2.jpg\" class=\"full\" \/>\n<p><\/p>\n<p>Electrochemically reversible Mg<sub>3<\/sub>Bi<sub>2<\/sub> intermetallic anode and visualized Mg<sup>2+ <\/sup>diffusion pathways by BVS mapping.<\/p>\n<\/div>\n<div class=\"col-md-6 mt-md-3\"><img decoding=\"async\" src=\"https:\/\/wwwchem.sci.hokudai.ac.jp\/~inorganic\/wp-content\/uploads\/2023\/06\/zu3.jpg\" class=\"full\" \/>\n<p><\/p>\n<p>Reversible phase transition of garnet-type lithium ion conductor: Li<sub>7<\/sub>La<sub>3<\/sub>Zr<sub>2<\/sub>O<sub>12<\/sub> and its ionic conductivity.\u00a0<\/p>\n<\/div>\n<div class=\"col-md-6 mt-md-3\"><img decoding=\"async\" src=\"https:\/\/wwwchem.sci.hokudai.ac.jp\/~inorganic\/wp-content\/uploads\/2023\/06\/zu4.jpg\" class=\"full\" \/>\n<p><\/p>\n<p>Comparison of the surface morphology of lithium metal (top left) and magnesium metal (top right) deposited at same current density of 2 mA cm<sup>-2<\/sup>.<\/p>\n<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"<h2>Research<\/h2>\n<ul>\n<li><a href=\"#1\">Solid-state ionic materials for next-generation battery applications<\/a><\/li>\n<li><a href=\"#2\">Low-temperature synthesis of complex metal oxides<\/a><\/li>\n<li><a href=\"#3\">Crystal growth mechanisms in less noble metal electrodeposition<\/a><\/li>\n<\/ul>\n","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"page-en.php","meta":[],"_links":{"self":[{"href":"https:\/\/wwwchem.sci.hokudai.ac.jp\/~inorganic\/wp-json\/wp\/v2\/pages\/171"}],"collection":[{"href":"https:\/\/wwwchem.sci.hokudai.ac.jp\/~inorganic\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/wwwchem.sci.hokudai.ac.jp\/~inorganic\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/wwwchem.sci.hokudai.ac.jp\/~inorganic\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/wwwchem.sci.hokudai.ac.jp\/~inorganic\/wp-json\/wp\/v2\/comments?post=171"}],"version-history":[{"count":22,"href":"https:\/\/wwwchem.sci.hokudai.ac.jp\/~inorganic\/wp-json\/wp\/v2\/pages\/171\/revisions"}],"predecessor-version":[{"id":826,"href":"https:\/\/wwwchem.sci.hokudai.ac.jp\/~inorganic\/wp-json\/wp\/v2\/pages\/171\/revisions\/826"}],"wp:attachment":[{"href":"https:\/\/wwwchem.sci.hokudai.ac.jp\/~inorganic\/wp-json\/wp\/v2\/media?parent=171"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
