Resumen de Advances in carbon nanofiber-based supercapacitor
Nowadays, our modern society huge challenges related to energy, savings as well as energy management, to improve and extend the standar of living to a growin population over 7000 million people, and do it with sustainable technologies becomes our main survival role play. Energy storage is a critical question to obtain a complete energy management system. Storage devices, suitably controlled by modern fast power electronic converters, may play a fundamental role in facing the challenge of global energy savings. In the present work, a new storage system based in electrochemical double layer capacitor has been developed and tested. The present doctoral thesis gives background related to energy storage based on supercapacitors. It attempts to place the supercapacitor device in context of available and future technologies for alternative energy systems management. Limitations of cells and electrodes are introduced. Ionic transport in active carbon and carbon nanofiber electrodes and possible restrictions in carbon nanostructured porous systems are studied and a novelty method to solve them are described. There are some open issues in the supercapacitor development, in this thesis the major challenges are introduced and how we can go beyond them, become the major objective. The results from the studies are presented in this thesis together with the scientific papers this thesis is based on.
