Because high tortuosities in porous electrodes are linked to lower delivered energy and power densities, in this paper, we experimentally and computationally study tortuosity and consider possible approaches to decrease it. We investigate the effect of electrode processing on the tortuosity of in-house fabricated porous electrodes, using three-dimensionally reconstructed microstructures obtained by synchrotron x-ray tomography. Computer-generated electrodes are used to understand the experimental findings and assess the impact of particle size distribution and particle packing on tortuosity and reactive area density. We highlight the limitations and tradeoffs of reducing tortuosity and develop a practical set of guidelines for active material manufacture and electrode preparation.<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p class=\"post-excerpt\" class=\"post-excerpt\">D-W Chung, M Ebner, DR Ely, V Wood, RE Garc\u00eda &#8220;Validity of&hellip;<\/p>\n<div class=\"link-more\"><a href=\"https:\/\/engineering.purdue.edu\/ComputationalMaterials\/index.php\/2017\/11\/04\/d-w-chung-m-ebner-dr-ely-v-wood-re-garcia-validity-of-the-bruggeman-relation-for-porous-electrodes-modelling-and-simulation-in-materials-science-and-engineering-217074009-2013\/\">Continue reading<span class=\"screen-reader-text\"> &#8220;D-W Chung, M Ebner, DR Ely, V Wood, RE Garc\u00eda &#8220;Validity of the Bruggeman relation for porous electrodes.&#8221;\u00a0Modelling and Simulation in Materials Science and Engineering. 21(7):074009, 2013.&#8221;<\/span>&hellip;<\/a><\/div>\n<div class=\"link-more\"><a href=\"https:\/\/engineering.purdue.edu\/ComputationalMaterials\/index.php\/2017\/11\/04\/d-w-chung-m-ebner-dr-ely-v-wood-re-garcia-validity-of-the-bruggeman-relation-for-porous-electrodes-modelling-and-simulation-in-materials-science-and-engineering-217074009-2013\/\">Continue reading<span class=\"screen-reader-text\"> \"D-W Chung, M Ebner, DR Ely, V Wood, RE Garc\u00eda &#8220;Validity of the Bruggeman relation for porous electrodes.&#8221;\u00a0Modelling and Simulation in Materials Science and Engineering. 21(7):074009, 2013.\"<\/span>&hellip;<\/a><\/div>","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"advanced_seo_description":"","jetpack_publicize_message":"","jetpack_is_tweetstorm":false,"jetpack_publicize_feature_enabled":true},"categories":[45],"tags":[9,14,15,62],"jetpack_publicize_connections":[],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"jetpack_shortlink":"https:\/\/wp.me\/peeeSR-7J","jetpack_likes_enabled":true,"jetpack-related-posts":[{"id":494,"url":"https:\/\/engineering.purdue.edu\/ComputationalMaterials\/index.php\/2017\/11\/04\/m-ebner-d%e2%80%90w-chung-re-garcia-v-wood-tortuosity-anisotropy-in-lithium%e2%80%90ion-battery-electrodes-advanced-energy-materials-451301278-2014\/","url_meta":{"origin":479,"position":0},"title":"M Ebner, D\u2010W Chung, RE Garc\u00eda, V Wood &#8220;Tortuosity Anisotropy in Lithium\u2010Ion Battery Electrodes.&#8221;\u00a0Advanced Energy Materials, 4(5):1301278, 2014.","date":"11\/04\/2017","format":false,"excerpt":"M Ebner, D\u2010W Chung, RE Garc\u00eda, V Wood \"Tortuosity Anisotropy in Lithium\u2010Ion Battery Electrodes.\"\u00a0Advanced Energy Materials, 4(5):1301278, 2014.
