2. 1. Microphase Separated Cation Conducting Polymers : Design, Synthesis, and Properties

   Author : Hannes Nederstedt; Centrum för analys och syntes; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Polymer; Litiumbatteri; Mikrofasseparering; Bränslceller; Elektrolyt; Polymerelektrolyt; Polymera bränslecellsmembran; Polymer electrolyte fuel cells; Polymer electrolyte; Polymer electrolyte membrane; Microphase separation; Lithium battery; Polymer; Fuel cell; Proton exchange membrane PEM ;

   Abstract : This thesis describes the synthesis and properties of five different cation conducting polymer systems. These systems were designed so that the polymers would be able to microphase separate into distinct phases with one phase for mechanical strength and one for ionic conductivity. READ MORE

4. 2. Structural Lithium Ion Battery Electrolytes

   Author : Niklas Ihrner; Mats Johansson; Daniel Brandell; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Structural batteries; Structural battery electrolyte; Lithium ion batteries; Polymerization induced phase separation; Carbon fibers; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Abstract : A major challenge in the electrification of vehicles in the transport industry is that batteries are heavy, which reduces their effectiveness in mobile applications. A solution to this is structural batteries, which are batteries that can carry mechanical load while simultaneously storing energy. READ MORE

5. 3. Functional Binders at the Interface of Negative and Positive Electrodes in Lithium Batteries

   Author : Fabian Jeschull; Daniel Brandell; Gerrit Boschloo; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; binder; lithium-sulfur batteries; graphite; lithium-ion batteries; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

   Abstract : In this thesis, electrode binders as vital components in the fabrication of composite electrodes for lithium-ion (LIB) and lithium-sulfur batteries (LiSB) have been investigated.Poly(vinylidene difluoride) (PVdF) was studied as binder for sulfur-carbon positive electrodes by a combination of galvanostatic cycling and nitrogen absorption.

6. 4. Lithium iron phosphates as cathode materials in lithium batteries

   Author : Anna S. Andersson; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; lithium batteries; cathode materials; lithium iron phosphates; magnetic properties; Kemi; Chemistry; Kemi; Inorganic Chemistry; oorganisk kemi;

   Abstract : Iron-based oxides are perhaps the only realistic cathode materials for electric and electric-hybrid vehicle applications. Two types of lithium iron phosphate, LiFePO4 andR-Li3Fe2(PO4)3, have been investigated for use within the lithium/lithium-ion polymer batteryconcept. READ MORE

7. 5. Solid Polymer Lithium-Ion Conducting Electrolytes for Structural Batteries

   Author : Markus Willgert; Mats Johansson; Alexander Bismarck; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : This work comprises the manufacture and characterization of solid polymer lithium ion conducting electrolytes for structural batteries. In the study, polymer films are produced in situ via a rapid versatile UV irradiation polymerization route, in which ethylene oxide methacrylates are polymerized into thermoset networks. READ MORE
