11. Pharmaceutical binders and their function in directly compressed tablets : Mechanistic studies on the effect of dry binders on mechanical strength, pore structure and disintegration of tablets
Sammanfattning : In this thesis, the strength-enhancing mechanisms of dry binders in direct compression were studied. The systems investigated were binary mixtures containing various compounds and binders. Among the binders used were a series of different molecular weights of polyethylene glycol. LÄS MER
12. ICME guided development of cemented carbides with alternative binder systems
Sammanfattning : The development of alternative binder systems for tungsten carbide (WC) based cemented carbides has again become of relevance due to possible changes in EU regulations regarding the use of Cobalt (Co). A framework for the ICME (Integrated Computational Materials Engineering) based Materials Design is presented to accelerate the development of alternative binder systems. LÄS MER
13. Polymers at the Electrode-Electrolyte Interface : Negative Electrode Binders for Lithium-Ion Batteries
Sammanfattning : We are today experiencing an increasing demand for high energy density storage devices like the lithium-ion battery for applications in portable electronic devices, electric vehicles (EV) and as interim storage for renewable energy. High capacity retention and long cycle life are prerequisites, particularly for the EV market. LÄS MER
14. Wood-based Materials for Lithium-ion Batteries
Sammanfattning : Lithium-ion batteries (LIB) have become very important recently as power sources for portable electronics and electric vehicles. Today non-renewable petroleum-based polymers are used as binders in state-of-the-art LIB. Therefore, it is essential to investigate alternative binders, which are environmentally friendly and inexpensive. LÄS MER
15. Functional Binders at the Interface of Negative and Positive Electrodes in Lithium Batteries
Sammanfattning : 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.
