Specifically, the tortuosity and porosity of currently used electrodes is described through the well-known Bruggeman relation for perfectly spherical particles. Experimentally, however, it has been found that material properties can greatly deviate from the perfect-sphere ideal. The current project has made contributions that extend the well-established porous electrode theory to\u00a0overcome these deficiencies. \u00a0We are developing theories that capture the average response of electrochemical systems, but will include the statistically rich spatial distribution of materials and associated microstructural properties.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p class=\"post-excerpt\" class=\"post-excerpt\">Currently existing theories and models to describe rechargeable lithium-ion batteries are based&hellip;<\/p>\n","protected":false},"author":1,"featured_media":206,"template":"","meta":{"advanced_seo_description":""},"project_category":[34,28],"project_tag":[35,36,31,32,37],"jetpack_sharing_enabled":true,"jetpack_likes_enabled":true,"_links":{"self":[{"href":"https:\/\/engineering.purdue.edu\/ComputationalMaterials\/index.php\/wp-json\/wp\/v2\/wm_projects\/243"}],"collection":[{"href":"https:\/\/engineering.purdue.edu\/ComputationalMaterials\/index.php\/wp-json\/wp\/v2\/wm_projects"}],"about":[{"href":"https:\/\/engineering.purdue.edu\/ComputationalMaterials\/index.php\/wp-json\/wp\/v2\/types\/wm_projects"}],"author":[{"embeddable":true,"href":"https:\/\/engineering.purdue.edu\/ComputationalMaterials\/index.php\/wp-json\/wp\/v2\/users\/1"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/engineering.purdue.edu\/ComputationalMaterials\/index.php\/wp-json\/wp\/v2\/media\/206"}],"wp:attachment":[{"href":"https:\/\/engineering.purdue.edu\/ComputationalMaterials\/index.php\/wp-json\/wp\/v2\/media?parent=243"}],"wp:term":[{"taxonomy":"project_category","embeddable":true,"href":"https:\/\/engineering.purdue.edu\/ComputationalMaterials\/index.php\/wp-json\/wp\/v2\/project_category?post=243"},{"taxonomy":"project_tag","embeddable":true,"href":"https:\/\/engineering.purdue.edu\/ComputationalMaterials\/index.php\/wp-json\/wp\/v2\/project_tag?post=243"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
