1. 1. Operando detection of Li-plating by online gas analysis and acoustic emission monitoring

   University essay from Uppsala universitet/Strukturkemi

   Author : Inti Espinoza Ramos; [2023]
   Keywords : Li-ion batteries; graphite; solid electrolyte interphase; lithium plating; online gas analysis; operando acoustic emission monitoring;

   Abstract : Lithium ion batteries (LIBs) are widely used for storing and converting chemical energy into electrical energy. During battery operation, lithium ions move between electrode materials, enabling energy storage. However, aging mechanisms like lithium plating can negatively impact battery performance and lifetime. READ MORE

3. 2. Investigation of stability in high salt polymer electrolytes for sodium batteries

   University essay from Uppsala universitet/Strukturkemi

   Author : Fengnan Yuan; [2022]
   Keywords : ;

   Abstract : Poly(trimethylene carbonate)–sodium bis(fluorosulfonyl)imide system shows a promising performance as polymer-in-salt electrolytes. The polymer electrolytes with salts concentration from 62% to 71% were tested through DSC, FTIR, EIS and constant current cycling. The solubility of the salts varies in different salts in PTMC.

4. 3. Evaluation of welding joint methods for a prismatic battery cell module

   University essay from Lunds universitet/Innovation

   Author : William Hellingwerf; [2021]
   Keywords : Aluminium welding methods; Battery module; Prismatic cell; Weld strength; Weld analysis; Weld temperature simulation; Technology and Engineering;

   Abstract : Prismatic battery cells swell due to a number of different factors, such as state of charge, temperature and irreversibly with charge cycling. Cell health can be improved by restricting the swelling of the cell, and therefore, the container which holds the cells, the module, should be able to restrict the swelling, and thus withstand the force exerted by the cells.

5. 4. Prussian White In Sodium- Ion Batteries : An evaluation of organic and inorganic coatings on active material particles

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Philip Jansson; [2021]
   Keywords : Sodium-ion batteries; Prussian White; Coating; Surface engineering; Zinc oxide; Polyaniline; Natriumjonbatterier; Berlinervitt; Beläggning; Ytmodifiering; Zinkoxid; Polyanilin;

   Abstract : Emerging markets in electrochemical energy storage, such as stationary grid storage, coupled with future concerns over the availability of lithium, places sodium-ion battery (SIB) technologies at a unique position to enter the market as a commercially viable alternative. Current shortcomings in the performance of cathode materials in SIBs would necessarily need to be addressed if this technology is to compete with existing commercial lithium-ion battery counterparts.

6. 5. Study of Environmental Effects on Photo-MultiplierTubes for the X-ray Polarimetry Mission XL-Calibur

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Jonathan Karlsson; Sebastian Alveteg; [2021]
   Keywords : ;

   Abstract : XL-Calibur is a balloon-borne hard X-ray polarimetry mission with goals to analyze celestial objects too small and distant to be imaged. A crucial part of XL-Calibur is the anti-coincidence shield which through active collimation reduces unwanted hits when gathering data. READ MORE
