1. 1. Low-Cost, Environmentally Friendly Electric Double-Layer Capacitors : Concept, Materials and Production

   Författare :Britta Andres; Håkan Olin; Christina Dahlström; Jonas Örtegren; Renyun Zhang; Mittuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electric Double-Layer Capacitor; Graphite; Cellulose Nanofibers; Large-Scale; Mass Balancing; Metal-Free;

   Sammanfattning : Today’s society is currently performing an exit from fossilfuel energy sources. The change to sustainable alternativesrequires inexpensive and environmentally friendly energy storagedevices. However, most current devices contain expensive,rare or toxic materials. These materials must be replaced bylow-cost, abundant, nontoxic components. LÄS MER

3. 2. Coarse-Grained Models of Ionic Solutions

   Författare :Ryan Szparaga; Beräkningskemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Monte Carlo; Classical Density Functional Theory; Coarse-Grained Models; Ionic Liquids; Prewetting; Capillary Condensation; Electric Double Layer; Differential Capacitance.;

   Sammanfattning : Room-temperature ionic liquids (RTILs) are compounds composed entirely of ions, which are liquid at temperatures below 100 degrees Celsius. Their high ionic strength and strong coupling make them useful for a number of applications, e.g. as electrolytes in supercapacitors. LÄS MER

4. 3. Paper-based Supercapacitors

   Författare :Britta Andres; Håkan Olin; Mats Sandberg; Mittuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; graphene; graphite; paper; nano fibrillated cellulose; supercapacitor; electric double-layer capacitor; energy storage; roll-to-roll; coating; kinetic energy recovery;

   Sammanfattning : The growing market of mobile electronic devices, renewable off-grid energy sources and electric vehicles requires high-performance energy storage devices. Rechargeable batteries are usually the first choice due to their high energy density. However, supercapacitors have a higher power density and longer life-time compared to batteries. LÄS MER

5. 4. Electrolyte-Based Organic Electronic Devices

   Författare :Elias Said; Magnus Berggren; Robert Forchheimer; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Conjugated polymers; Electrolytes; Organic Field Effect Transistors; Physics; Fysik;

   Sammanfattning : The discovery of semi-conducting and conducting organic materials has opened new possibilities for electronic devices and systems. Applications, previously unattainable for conventional electronics, have become possible thanks to the development of conjugated polymers. LÄS MER

7. 5. Upscaling Organic Electronic Devices

   Författare :Abdellah Malti; Xavier Crispin; Ananth Dodabalapur; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Conventional electronics based on silicon, germanium, or compounds of gallium require prohibitively expensive investments. A state-of-the-art microprocessor fabrication facility can cost up to $15 billion while using environmentally hazardous processes. LÄS MER
