El fabricante de ultracondensadores Skeleton Technologies ha anunciado una cooperaci\u00f3n con el Instituto de Tecnolog\u00eda de Karlsruhe (KIT). Los socios trabajan juntos en el desarrollo de una bater\u00eda de grafeno con un tiempo de carga de s\u00f3lo 15 segundos.<\/p>\n
El tiempo de carga extremadamente corto combinado con cientos de miles de ciclos de carga deber\u00edan hacer de la \"SuperBater\u00eda\" una soluci\u00f3n perfecta para la e-movilidad, afirma con confianza el fabricante en el anuncio. La bater\u00eda se basa en el material de carbono patentado por Skeleton, al que denominan grafeno curvado, que debe permitir el alto rendimiento y la larga vida \u00fatil de los ultracondensadores ahora tambi\u00e9n en una bater\u00eda de grafeno, en combinaci\u00f3n con materiales especialmente desarrollados en el KIT.<\/p>\n
\"La tecnolog\u00eda SuperBattery es un factor cr\u00edtico para la industria automovil\u00edstica\", afirma Taavi Madiberk, director general de Skeleton Technologies. Aparte del tiempo de carga de 15 segundos, la empresa estonia que opera una planta en el estado alem\u00e1n de Sajonia no ha facilitado m\u00e1s datos sobre la bater\u00eda de grafeno.<\/p>\n
A la pregunta de electrive<\/em>, un portavoz explica que el tiempo de carga mencionado puede lograrse no s\u00f3lo en el laboratorio, sino tambi\u00e9n en aplicaciones reales. Sin embargo, no especifican cu\u00e1nta energ\u00eda puede transferirse en este corto espacio de tiempo. S\u00f3lo esto: \"La carga garantiza que la 'SuperBater\u00eda' proporcione la autonom\u00eda adicional para los desplazamientos diarios o las distancias cortas en cuesti\u00f3n de segundos.<\/p>\n <\/p>","protected":false},"excerpt":{"rendered":" El fabricante de ultracondensadores Skeleton Technologies ha anunciado una cooperaci\u00f3n con el Instituto de Tecnolog\u00eda de Karlsruhe (KIT).

Hybrid cars should be able to reduce fuel consumption and CO2 emissions in the double-digit percentage range, and hybrid cars should be able to accelerate as fast as purely electric cars thanks to the rapid energy release of the battery.<\/p>\n More interesting, however, might be the use in battery-electric cars as a supplement, not instead of the lithium-ion battery. “The SuperBattery can avoid the typical oversizing of batteries and corresponding cooling systems, which leads to significantly lower costs and a longer service life of the systems,” says the company spokesperson. “Essentially, the SuperBattery serves as a buffer for peak power loads for charging and discharging, which are normally the most demanding tasks for today’s batteries.”<\/p>\n This is one of the reasons why the graphene battery is used as a buffer rather than as the sole traction battery: Its energy density cannot yet keep up with other battery types. When asked, Skeleton gives a value of 60 Wh\/kg here, which is roughly on a par with nickel-metal hydride batteries. Lithium-ion batteries reach 120 to 180 Wh\/kg. Tesla boss Elon Musk announced in a tweet in August that long-life cells with an energy density of 400 Wh\/kg would be available in three to four years.<\/p>\n It should also be possible to use them as buffer batteries in fuel cell vehicles, in this case instead of the buffer batteries made of lithium-ion cells currently used. According to Skeleton, the regenerative braking of the FCEV is to be improved and the fuel cell system itself is to be designed smaller. As with hybrid cars, the battery should enable good acceleration values due to its high current output. Something that FCEVs usually lack compared to BEVs.<\/p>\n Skeleton Technologies, according to its own statements, has recently signed a letter of intent for one billion euros with a “leading automotive OEM” to bring the technology to market. Although the automotive industry is the most visible sector, the SuperBattery is also expected to be suitable for industrial applications or as a buffer storage to stabilise the power grid, according to Skeleton’s spokesperson.<\/p>\n With reporting by Sebastian Schaal, Germany.<\/em><\/p>\n Source: Press release via email<\/em><\/p>\n"},"_links":{"self":[{"href":"https:\/\/www.electrive.com\/es\/wp-json\/wp\/v2\/posts\/139080","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\/22"}],"replies":[{"embeddable":true,"href":"https:\/\/www.electrive.com\/es\/wp-json\/wp\/v2\/comments?post=139080"}],"version-history":[{"count":0,"href":"https:\/\/www.electrive.com\/es\/wp-json\/wp\/v2\/posts\/139080\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.electrive.com\/es\/wp-json\/wp\/v2\/media\/139062"}],"wp:attachment":[{"href":"https:\/\/www.electrive.com\/es\/wp-json\/wp\/v2\/media?parent=139080"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.electrive.com\/es\/wp-json\/wp\/v2\/categories?post=139080"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.electrive.com\/es\/wp-json\/wp\/v2\/tags?post=139080"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}Graphene battery still has a low energy density<\/h2>\n
