In addition, the shortage (0.0017 wt% in the Earth&#8217;s crust) and uneven crustal distribution of lithium also limit its further development and application. Potassium (2.7 wt% in the earth&#8217;s crust) has properties similar to lithium and abundant reserves. Therefore, as an alternative to LIBs, potassium ion batteries (PIBs) have become the focus of research. Potassium (2.92 V vs. standard hydrogen electrode) has a standard electrode potential closer to Li (3.04 V vs. SHE) than the standard electrode potential of Na (2.71 V vs. SHE), Mg (2.37 V vs. SHE) and Al (1.66 V vs. SHE). This means that PIBs may provide a higher energy density and working voltage. Consequently, it is of great significance to explore potential electrode materials and study their potassium storage mechanism.&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\n Click here for original story, <a href=\"https:\/\/phys.org\/news\/2021-01-carbon-based-cell-like-spheres-robust-potassium-anode.html\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Construction of carbon-based cell-like-spheres for robust potassium anode<\/a>&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\nSource: Phys.org&#013;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>With the rapid development of smart portable electronics and electric vehicles, the consumption of lithium resources will increase dramatically and the cost of lithium-ion batteries (LIBs) may increase significantly in&hellip; <\/p>\n","protected":false},"author":1,"featured_media":615444,"comment_status":"false","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[41],"tags":[],"class_list":["post-677865","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-phys-org"],"_links":{"self":[{"href":"https:\/\/spaceweekly.com\/index.php?rest_route=\/wp\/v2\/posts\/677865","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/spaceweekly.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/spaceweekly.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/spaceweekly.com\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/spaceweekly.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=677865"}],"version-history":[{"count":0,"href":"https:\/\/spaceweekly.com\/index.php?rest_route=\/wp\/v2\/posts\/677865\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/spaceweekly.com\/index.php?rest_route=\/wp\/v2\/media\/615444"}],"wp:attachment":[{"href":"https:\/\/spaceweekly.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=677865"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/spaceweekly.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=677865"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/spaceweekly.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=677865"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
