ultracapacitor: a bateria do futuro?

Diz um artigo aí que no futuro próximo as baterias cederão gentilmente o seu lugar a ultracapacitores. Capacitores já existem entre nós tem tempo e eu particularmente não gosto deles. Nas aulas de eletrônica analógica eles sempre apareciam do nada para por ordem aos circuitos que na teoria estavam corretos, mas implementados precisavam a toda hora de um capacitorzinho. Pleonasmo, eu sei. Mas “back to the cold cow”: ultracapacitores são melhores do que os capacitores atuais por que utilizam a tecnologia de nanotubos para aumentar a superficie interna. Com a tecnologia de nanotubos, diz o artigo, essa superficie foi aumentada em uma ordem de gradeza, ou seja, se hoje existem capacitores com 2000 cm2, com nano tubos o valor vai 50000 cm2. Com isso até o tempo para carregar diminui. uau.

Uma resposta para “ultracapacitor: a bateria do futuro?”

  1. […] anos atrás eu comentei sobre como os ultracapacitores iriam ganhar o espaço das baterias em determinados segmentos. Pois bem, este ano finalmente uma aplicação de […]
