<\/p>\n

eg\u00fan un informe de Reuters<\/strong>, Panasonic <\/strong>pretende aumentar la densidad energ\u00e9tica <\/strong>de las bater\u00edas de iones de litio suministradas para Tesla (cil\u00edndricas del tipo \u201c2170\u201d) en un 20% en 5 a\u00f1os.<\/p>\n

El informe no especifica si estamos hablando de densidad gravim\u00e9trica o volum\u00e9trica (o ambas).<\/p>\n

Panasonic <\/strong>produce c\u00e9lulas cil\u00edndricas tipo \u201c2170\u201d \u2013 n\u00edquel-cobalto-aluminio (NCA) \u2013 para Tesla <\/strong>en la f\u00e1brica Tesla Gigafactory en Nevada desde 2017. Las bater\u00edas de Tesla-Panasonic se consideran las m\u00e1s densas energ\u00e9ticamente hablando.<\/mark><\/p>\n

\"\"<\/figure>\n

Aunque la mejora del 20% en cinco a\u00f1os es significativa<\/mark>, probablemente se dividir\u00e1 en pasos m\u00e1s peque\u00f1os y parece que el primer aumento del 5% llegar\u00e1 m\u00e1s adelante este a\u00f1o.<\/p>\n

La compa\u00f1\u00eda japonesa est\u00e1 lista con la tecnolog\u00eda mejorada y a partir de septiembre de 2020 comenzar\u00e1 a convertir las l\u00edneas en Gigafactory en Nevada.<\/p>\n

<\/div>\n

Nueva era<\/h2>\n

\u201cA partir de septiembre, la empresa comenzar\u00e1 a convertir las l\u00edneas de su f\u00e1brica en Nevada que opera con Tesla mientras se prepara para aumentar a\u00fan m\u00e1s la densidad de energ\u00eda de las c\u00e9lulas\u201d, dijo Yasuaki\u00a0Takamoto<\/strong>, gerente de energ\u00eda de Tesla.<\/p>\n

Los \u00fanicos dos modelos de Tesla que actualmente usan las bater\u00edas \u201c2170\u201d son el model 3 y el model Y (a los que se unir\u00e1n m\u00e1s adelante el Semi). El Model S\/Model X todav\u00eda est\u00e1n equipados con \u201c18650\u201d.<\/mark><\/p>\n

Panasonic tambi\u00e9n anunci\u00f3 que, actualmente, el contenido de cobalto en las bater\u00edas para Tesla est\u00e1 por debajo del 5%, que podr\u00eda ser el m\u00e1s bajo de la industria<\/a>.<\/p>\n

\"\"<\/figure>\n

\u201cPanasonic ya ha reducido el contenido de cobalto por debajo del 5% en el c\u00e1todo NCA y planea mejorar sus bater\u00edas por etapas\u201d, asegur\u00f3 Takamoto.<\/p>\n

El pr\u00f3ximo paso ser\u00e1 la fabricaci\u00f3n de bater\u00edas sin cobalto en 2-3 a\u00f1os, aunque no estamos seguros de si estamos hablando de una tecnolog\u00eda mejorada de las c\u00e9lulas existentes, o de una nueva (o la propia versi\u00f3n de Panasonic de LFP), que simplemente no usa el cobalto. El problema con la LFP es su densidad de energ\u00eda significativamente menor (podr\u00eda ser menos de la mitad de la NCA), aunque el coste tambi\u00e9n es menor.<\/mark><\/p>\n

\u201cPara controlar los riesgos de seguridad asociados a una mayor densidad y menos cobalto, Panasonic est\u00e1 ajustando la composici\u00f3n y el dise\u00f1o para una mejor estabilidad t\u00e9rmica\u201d, agreg\u00f3 .<\/p>\n

Y por \u00faltimo asegur\u00f3: \u201cUna versi\u00f3n sin cobalto<\/a>, por otro lado, reducir\u00eda la dependencia de un costoso y controvertido componente, que hace que las bater\u00edas sean estables pero plantea problemas \u00e9ticos dadas las controvertidas condiciones laborales del principal productor, la Rep\u00fablica Democr\u00e1tica del Congo\u201d.<\/p>\n
