Softwood Lignin as a Sustainable Feedstock for Porous Carbons as Active Material for Supercapacitors Using an Ionic Liquid Electrolyte
(American Chemical Society, 2017-05)
We report on the facile synthesis of porous carbons based on a biopolymer lignin employing a two-step process which includes the activation by KOH in various amounts under an inert gas atmosphere. The resulting carbons are ...
Cross-linking effect on thermal, conducting and electrochemical properties of an elastomeric polymer electrolyte
(Elsevier Science BvAmsterdamHolanda, 2003)
Estrutura e propriedades de materiais eletrólitos e compósitos poliméricos e sua aplicação em capacitores eletroquímicos de dupla camada
(Universidade Federal de Minas GeraisUFMG, 2008-03-31)
In this work, a fundamental study of different materials (blends, composites and polymeric electrolytes), all in the solid state, was accomplished. These materials were prepared with poly(ethylene oxide) and thermoplastic ...
Estudo da influência do tempo de sinterização na produção de capacitores eletrolíticos de nióbio
(Universidade Federal do Rio Grande do NorteBrasilUFRNEngenharia ElétricaCentro de Tecnologia, 2023)
Nanoscale origins of super-capacitance phenomena
(2019-02-28)
We review the origins of capacitive phenomena at the nanoscale to demonstrate that electrochemistry cannot be understood without a critical re-reading of nanoscale electronics, and vice-versa. The fundamentals are stated ...
Photovoltaic System for Microinverter Applications Based on a Non-Electrolytic-Capacitor Boost Converter and a Sliding-Mode Controller
(Cartagena de Indias, 2022-09-15)
This paper presents a photovoltaic (PV) system designed to reduce the DC-link capacitance present in double-stage PV microinverters without increasing the capacitor interfacing the PV source. This solution is based on a ...
Diamond films as support for electrochemical systems for energy conversion and storage
(2019-01-01)
Many efforts have been dedicated to develop and study different catalysts supported materials for energy storage and conversion. Polymer electrolyte membranes (PEM) and capacitors have been topics of special interest for ...
