  1. 1. Carbon materials from biomass for supercapacitors

    University essay from KTH/Tillämpad fysik

    Author : Jaskaran Singh Malhotra; [2020]
    Keywords : Supercapacitors; Activated Carbon; Energy Storage; Biomass conversion; Electrochemical Energy Storage; Pyrolysis; Superkapacitatorer; Aktivt kol; Energilagring; Biomassa omvandling; Elektrokemisk energilagring; Pyrolys;

    Abstract : The fast pyrolysis plant at RISE – ETC, Piteå produces carbon rich chars in bulk from various sources of biomass as feedstock. These in-house manufactured carbon rich chars were upgraded via pyrolysis as well as chemical activation using KOH to enhance their potential as an electrode material for supercapacitors. READ MORE

  3. 2. Determining the voltage range of a carbon-based supercapacitor

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Thomas Wells; [2014]
    Keywords : Carbon electrodes; aqueous electrolytes; sodium sulphate; lithium sulphate; super capacitor; EDLC; electrochemical double layer capacitor; EDL; graphite; nano porous;

    Abstract : The focus of this thesis has been to determine the usable voltage range of carbon-based supercapacitors (SC). Supercapacitors are a relatively new type of capacitors with a vast increase in capacitance compared to capacitors which utilize a dielectric as charge separator. A SC consists of two electrodes and an electrolyte separating the electrodes. READ MORE

  4. 3. Control strategy and lifetime optimization of Electrochemical Double-Layer Capacitors

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Samir Alagic; Viktor Nordgren; [2014]
    Keywords : Supercapacitor; Ultracapacitor; Electrochemical Double-Layer Capacitor; Energy Storage; Power Source; MATLAB; Simulink; Embedded Systems; Aging; Lifetime Estimation; Voltage Control; Control System.; Technology and Engineering;

    Abstract : Today, the most commonly used energy storage device in embedded systems is batteries. But unfortunately, batteries are associated with short lifetime. By introducing Electrochemical Double-Layer Capacitors (EDLCs) as an alternative power source, the lifetime of the backup energy source can be significantly increased. READ MORE
