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

2. Structural Lithium Ion Battery Electrolytes
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

3. Amphiphilic Graft Copolymer Electrolytes for Lithium-Ion Polymer Batteries. - Preparation and Characterisation
Abstract : In the present work amphiphilic graft copolymers were prepared by free radical copolymerization of macromonomers in solution. The graft copolymers consisted of methacrylate backbones bearing ethylene oxide (EO)n side chains of varying length as ionophilic groups, and fluorocarbon (CF2)6 side chains or hydrocarbon groups as ionophobic groups.

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