2. 16. Identifying Parameters for Aging-Adaptive Battery Management

   Author : Moritz Streb; Göran Lindbergh; Matilda Klett; Kandler Smith; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lithium-ion battery; Parameter estimation; Aging-adaptive usage; Electrochemical battery management; Litiumjonbatteri; Parameteruppskattning; Åldringsmedveten användning; Elektrokemisk batterikontroll; Chemical Engineering; Kemiteknik;

   Abstract : The modern transportation system is largely based on fossil fuels. To reduce this reliance on oil and gas and thereby drastically reduce emissions, a transition to renewable power sources is necessary. Lithium-ion batteries are the most established candidate for electromobility applications, with suitable energy and power densities. READ MORE

   Abstract : Surface film formation at the electrode/electrolyte interface in lithium-ion batteries has a crucial impact on battery performance and safety. This thesis describes the characterisation and treatment of electrode interfaces in lithium-ion batteries. READ MORE

5. 18. Preparation and Characterization of Electrochemical Devices for Energy Storage and Debonding

   Author : Simon Leijonmarck; Göran Lindbergh; Ann Cornell; Leif Nyholm; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; adhesives; carbon fiber; debonding; delamination; electropolymerization; flexible battery; lithium-ion battery; paper battery;

   Abstract : Within the framework of this thesis, three innovative electrochemical devices have been studied. A part of the work is devoted to an already existing device, laminates which are debonded by the application of a voltage. READ MORE

6. 19. State-of-Health Estimation of Li-ion Batteries: Cycle Life Test Methods

   Author : Jens Groot; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EV; DVA; ICA; cycle life test; HEV; battery testing; State-of-health; battery model; PHEV; lithium-ion battery; impedance spectroscopy;

   Abstract : Despite a rapid development, cost, performance and durability of the energy storage system are still a hindrance for a wide commercialisation of heavy-duty hybrid electric vehicles (HEV). The purpose of the work presented in this thesis is to investigate how different load cycle properties affect the cycle life and ageing processes of Li-ion cells developed for use in HEVs. READ MORE

7. 20. State-of-Health Estimation of Li-ion Batteries: Ageing Models
