  1. 1. Electrochemical Capacitors for Miniaturized Self-powered Systems

    Author : Qi Li; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; AC line filters; Electrode materials; Electrochemical capacitors; Miniaturized self-powered systems; Electrolyte materials; Energy storage;

    Abstract : Miniaturized self-powered systems with harvest-store-use architectures have been recognized as a key enabler to the internet-of-things (IoT), and further the internet-of-everything (IoE), 5G communication and tactile internet. Electrochemical capacitors (ECs), also known as supercapacitors, are promoted to be the energy storage component in such systems, because of their advantages such as an almost limitless cycle life that is ideal for the vision of “fit-and-forget” maintenance-free networks.

  2. 2. Electrochemical capacitors for miniaturized self-powered systems: challenges and solutions

    Author : Qi Li; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; redox electrolytes; a.c. line filters; miniaturized self-powered systems; carbon; bipolar; electrochemical capacitors; supercapacitors; energy storage; encapsulation;

    Abstract : Electrochemical capacitors (ECs), also known as supercapacitors, are recognized as a key technology that will enable miniaturized self-powered systems, which will constitute the hardware base nodes of the internet of things (IoT), the internet of everything (IoE) and the tactile internet. Systems employing ECs can be designed to be maintenance-free thanks to the ultra-long cycling stability of ECs. READ MORE

  3. 3. Polyelectrolyte-Based Capacitors and Transistors

    University dissertation from Norrköping : Linköping University Electronic Press

    Author : Oscar Larsson; Xavier Crispin; Janelle Leger; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic electronics; Polarization; Polyelectrolyte; Transistor; Polymer; Sensor; Capacitor; NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : Polymers are very attractive materials that can be tailored for specific needs and functionalities. Based on their chemical structure, they can for instance be made electrically insulating or semiconducting with specific mechanical properties. READ MORE

  4. 4. Polarization characteristics in polyelectrolyte thin film capacitors Targeting field-effect transistors and sensors

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Oscar Larsson; Xavier Crispin; Magnus Berggren; Nathaniel Robinson; Ludvig Edman; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Polymers are very attractive materials that can be tailored for specific needs and functionality. They can for instance be made electrically insulating or (semi)conducting, with specific mechanical properties. Polymers are often processable from a solution, which enables the use of low-cost manufacturing techniques to fabricate polymer devices. READ MORE

  5. 5. Electrochemical and ion transport characterisation of a nanoporous carbon derived from SiC

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Marcelo Zuleta; Pehr Björnbom; Derek Pletcher; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical engineering; Cottrell equation; radial diffusion; chronoamperometry; potential step measurements; microelectrode technique; nanoporous carbon; Kemiteknik; TECHNOLOGY Chemical engineering; TEKNIKVETENSKAP Kemiteknik;

    Abstract : In this doctoral project, a relatively new form of carbon material, with unique narrow pore size distribution around 7 Å and with uniform structure, has been electrochemically characterised using the single particle microelectrode technique. The carbon has been used as electrode material for supercapacitors. READ MORE
