Investigadores del Instituto Avanzado de Tecnolog\u00eda de Samsung han presentado el prototipo de una c\u00e9lula de bater\u00eda de estado s\u00f3lido, que ayudar\u00e1 a los coches el\u00e9ctricos a alcanzar una autonom\u00eda de 800 kil\u00f3metros y sobrevivir a 1.000 ciclos de carga. <\/p>\n
Los investigadores del instituto tambi\u00e9n han encontrado una soluci\u00f3n al problema de la formaci\u00f3n de dendritas en los \u00e1nodos de metal de litio que suelen utilizarse en las bater\u00edas de estado s\u00f3lido. Para ello, los investigadores de Samsung est\u00e1n utilizando una capa compuesta de plata y carbono para el \u00e1nodo. Esto no s\u00f3lo contrarresta el problema de las dendritas, sino que tambi\u00e9n garantiza una mayor capacidad y una vida \u00fatil m\u00e1s larga, seg\u00fan la empresa. Samsung afirma que este prototipo representa un \"avance revolucionario\".<\/p>\n
La capa compuesta de plata-carbono se desarroll\u00f3 principalmente como medida contra la formaci\u00f3n de dendritas, es decir, la cristalizaci\u00f3n en los \u00e1nodos de litio. Esta capa de nanocompuesto de Ag-C s\u00f3lo tiene 5 micr\u00f3metros de grosor, lo que permite a los desarrolladores reducir el grosor de los \u00e1nodos y aumentar la densidad energ\u00e9tica hasta 900 Wh\/L. Seg\u00fan Samsung, una bater\u00eda de estado s\u00f3lido construida con estas celdas puede ser alrededor de un 50% m\u00e1s peque\u00f1a que las bater\u00edas de iones de litio convencionales con una capacidad comparable.<\/p>\n
Las dendritas son dep\u00f3sitos de material sobre el \u00e1nodo de metal de litio. Dado que \"bloquean\" la superficie del \u00e1nodo, \u00e9ste ya no puede utilizarse plenamente. Si las dendritas crecen tanto que da\u00f1an la l\u00e1mina separadora entre el \u00e1nodo y el c\u00e1todo, pueden incluso afectar a la seguridad de la pila.<\/p>","protected":false},"excerpt":{"rendered":"

“The product of this study could be a seed technology for safer, high-performance batteries of the future,” says project leader Dongmin Im of the Samsung Advanced Institute of Technology (SAIT). “Going forward, we will continue to develop and refine all-solid-state battery materials and manufacturing technologies to help take EV battery innovation to the next level.”<\/p>\n
In the prototype that Samsung has developed for the presentation of the battery, there are enough pouch cells for a range of up to 800 kilometres in an electric car \u2013 but as always, such specifications should be treated with caution. Samsung also promises that the battery should survive up to 1,000 charging cycles, which extrapolates to a mileage of 800,000 kilometres.<\/p>\n
Despite the “groundbreaking” development, the prototype is not yet ready for the market. Initially, the materials are to be better matched in detail, and then the researchers want to start work on corresponding production processes for mass production.<\/p>\n
The timing of the Samsung announcement could also be motivated by corporate policy: In Japan, the Toyota group has been promising<\/a> to introduce a solid-state battery at the Olympic Games in Tokyo in the summer of 2020, but it remains to be seen how close they are to series production. Among other companies also working on solid-state technology are the Taiwanese company ProLogium<\/a> that presented a solid-state battery at CES, and Mercedes entered into a cooperation with Hydro-Qu\u00e9bec<\/a> for this purpose.<\/p>\n samsung.com<\/a>, theinvestor.co.kr<\/a><\/p>\n"},"_links":{"self":[{"href":"https:\/\/www.electrive.com\/es\/wp-json\/wp\/v2\/posts\/129676","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.electrive.com\/es\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.electrive.com\/es\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.electrive.com\/es\/wp-json\/wp\/v2\/users\/24"}],"replies":[{"embeddable":true,"href":"https:\/\/www.electrive.com\/es\/wp-json\/wp\/v2\/comments?post=129676"}],"version-history":[{"count":0,"href":"https:\/\/www.electrive.com\/es\/wp-json\/wp\/v2\/posts\/129676\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.electrive.com\/es\/wp-json\/wp\/v2\/media\/119187"}],"wp:attachment":[{"href":"https:\/\/www.electrive.com\/es\/wp-json\/wp\/v2\/media?parent=129676"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.electrive.com\/es\/wp-json\/wp\/v2\/categories?post=129676"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.electrive.com\/es\/wp-json\/wp\/v2\/tags?post=129676"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
