1. 1. Investigating self-discharge in a graphite dual-ion cell using in-situ Raman spectroscopy.

   University essay from Uppsala universitet/Strukturkemi

   Author : Ismail Yussuf Hassan; [2023]
   Keywords : graphite; dual-ion battery; parasitic reaction; cathode-electrolyte interface; anion intercalation; concentrated electrolyte; self-discharge; Raman spectroscopy;

   Abstract : Anion intercalation in the graphite positive electrode of a dual-ion battery requires high potential (> 4.3 V vs Li+/Li), which aggravates parasitic reactions involving electrolyte decomposition and Al corrosion, manifesting in poor coulombic efficiency, cycle life, and quick self-discharge.

3. 2. Graphene Based Aqueous Ammonium Dual-Ion Batteries

   University essay from Uppsala universitet/Strukturkemi

   Author : Arvid Sandberg; [2023]
   Keywords : Dual ion batteries; materials science; chemistry; organic polymer;

   Abstract : The global transition to renewable energy sources is placing high demands on the development of effective energy storage methods, the most prevalent being batteries. Dual-ion batteries are a new battery technology that takes advantage of the simultaneous intercalation of both cations and anions. READ MORE

4. 3. Method evaluation for probing DNA sorption to clay minerals : Evaluation of fluorescent and spectroscopic quantification of DNA as well as DNA interactions of Kaolinite and Montmorillonite

   University essay from Umeå universitet/Kemiska institutionen

   Author : Oskar Wangdell; [2022]
   Keywords : ;

   Abstract : The association of DNA/RNA to mineral surfaces is an emerging field with widespread applications from biotechnological solutions to paleogenetics. Evaluating available methods to quantify adsorption will be essential to further investigate how to control and predict loading of DNA onto minerals. READ MORE

5. 4. An investigation of the interactions between clay nanoplatelets in the presence of monovalent and divalent salts, as well as cationic peptides utilising atomistic molecular dynamics

   University essay from Lunds universitet/Kemiska institutionen

   Author : Mona Koder Hamid; [2020]
   Keywords : clay; molecular dynamics simulations; physical chemistry; fysikalisk kemi; theoretical chemistry; teoretisk kemi; Chemistry;

   Abstract : Clays are negatively charged nanoplatelets with a layered silicate structure. It has been observed from small angle X-ray scattering measurements, and coarse-grained molecular dynamics simulations (CG-MD) that clay nanoplatelets are able to form stacks, known as tactoids, in the presence of divalent or multivalent counterions [8, 5].

6. 5. Temperature Dependence of Resistance of a Ni-rich Li-ion Cathode

   University essay from Uppsala universitet/Strukturkemi

   Author : Ewa Cecilia Töyrä Mendez; [2020]
   Keywords : Battery; Electric Vehicles; Resistance; NMC811; Cathode; Ni;

   Abstract : Understanding the degradation mechanisms of Li-ion batteries is essential to gain insights into battery aging. The primary research area of this thesis is the positive electrode, NMC811. The purpose of the thesis is to understand how low and elevated temperatures affect the aging of NMC811, by considering the effects on resistance. READ MORE
