General Motors ha liderado una ronda de inversi\u00f3n de 139 millones de d\u00f3lares estadounidenses del especialista en bater\u00edas de estado s\u00f3lido SolidEnergy Systems (SES). Esto sigue a un acuerdo de desarrollo que la empresa automovil\u00edstica estadounidense hab\u00eda firmado en marzo con SES. <\/p>\n
SES es una empresa derivada del Instituto Tecnol\u00f3gico de Massachusetts (MIT) con sede en Singapur. Adem\u00e1s de General Motors, los inversores existentes SK, Temasek, Applied Ventures LLC, Shanghai Auto y Vertex se encuentran entre los patrocinadores de la ronda de financiaci\u00f3n que acaba de cerrarse. El promotor afirma que utilizar\u00e1 la nueva financiaci\u00f3n para acelerar el desarrollo tecnol\u00f3gico y la comercializaci\u00f3n de sus bater\u00edas de estado s\u00f3lido a base de metal de litio.<\/p>\n
SES hab\u00eda anunciado un tecnolog\u00eda de las pilas de litio metal en 2016<\/a> en el que el \u00e1nodo se sustituye por una l\u00e1mina de litio extremadamente fina. Esto podr\u00eda aumentar significativamente la densidad energ\u00e9tica hasta 500 Wh\/kg. General Motors est\u00e1 muy interesada en esta tecnolog\u00eda, ya que la empresa est\u00e1 planeando la pr\u00f3xima generaci\u00f3n de sus bater\u00edas Ultium con un \u00e1nodo de metal de litio, es decir, como una bater\u00eda de estado s\u00f3lido. GM coquetea as\u00ed con el mismo camino que el Grupo Volkswagen, que tambi\u00e9n ha llevado una especialista en bater\u00edas de estado s\u00f3lido a bordo con QuantumScape<\/a>. El mismo patr\u00f3n puede observarse con Ford y la empresa tecnol\u00f3gica SolidPower<\/a> (junto con Hyundai y BMW<\/a>).<\/p>\n SES describe la inversi\u00f3n de GM como la \"culminaci\u00f3n de casi seis a\u00f1os de trabajo con el gran fabricante de autom\u00f3viles\". La colaboraci\u00f3n se remonta a 2015. Como parte de un acuerdo de desarrollo recientemente acordado<\/a>, GM y SES planean construir un prototipo de l\u00ednea de producci\u00f3n de las c\u00e9lulas en Woburn, Massachusetts, para 2023. Para mediados de la d\u00e9cada, los socios quieren reducir los costes hasta un 60% en comparaci\u00f3n con las c\u00e9lulas utilizadas en los actuales Chevrolet Bolt y Bolt EUV.<\/p>","protected":false},"excerpt":{"rendered":" General Motors ha liderado una ronda de inversi\u00f3n de 139 millones de d\u00f3lares estadounidenses del especialista en bater\u00edas de estado s\u00f3lido SolidEnergy Systems (SES).

SES’s technology is said to be key to this. For the current generation of Ultium cells, GM is known to be working with LG Energy Systems. As part of their joint venture Ultium Cells, GM and LG are already building a battery cell plant in Ohio, which is expected to be completed in 2022. In early March, GM also confirmed reports that it was planning a second battery cell plant in the US. Meanwhile, LG has also given some key points on this.<\/p>\n “GM has been rapidly driving down battery cell costs and improving energy density, and our work with SES technology has incredible potential to deliver even better EV performance for customers who want more range at a lower cost,” expressed Matt Tsien, GM executive vice president and CTO. “This investment by GM and others will allow SES to accelerate their work and scale up their business.”<\/p>\n For its part, GM says it already has development expertise and numerous data series in the area of solid-state batteries: The first prototype cells are said to have already reeled off 150,000 simulated test miles in the research and development lab at GM’s Global Technical Center in Warren, Michigan.<\/p>\n techcrunch.com<\/a>,\u00a0prnewswire.com<\/a>,\u00a0ses.ai<\/a><\/p>\n"},"_links":{"self":[{"href":"https:\/\/www.electrive.com\/es\/wp-json\/wp\/v2\/posts\/153655","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=153655"}],"version-history":[{"count":0,"href":"https:\/\/www.electrive.com\/es\/wp-json\/wp\/v2\/posts\/153655\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.electrive.com\/es\/wp-json\/wp\/v2\/media\/153636"}],"wp:attachment":[{"href":"https:\/\/www.electrive.com\/es\/wp-json\/wp\/v2\/media?parent=153655"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.electrive.com\/es\/wp-json\/wp\/v2\/categories?post=153655"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.electrive.com\/es\/wp-json\/wp\/v2\/tags?post=153655"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
