4. 8. An Initial Exploration of Transition Metal Nitroprussides as Electrode Materials for Sodium-ion Batteries

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Strukturkemi

   Författare :Veronica Enblom; [2022]
   Nyckelord :Sodium-ion batteries; Transition metal nitroprussides; Electrode materials; Prussian blue analogues; Cathode materials; Nitrosyl redox; Anisotropic charge transfer; Hysteresis; Sustainable batteries;

   Sammanfattning : Na-ion batteries (NIBs) are expected to revolutionise the battery sector by promising an affordable technology while capitalising on sustainable development. To compete with Li-ion batteries, however, electrode materials with higher capacities need to be developed. LÄS MER

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

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

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

   Sammanfattning : 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.

7. 10. Recycling of Prussian White

   Kandidat-uppsats, Uppsala universitet/Institutionen för kemi - Ångström

   Författare :Agnes-Matilda Mattsson; Towa Eriksson; Caroline Löwnertz; Marielle Holmbom; [2021]
   Nyckelord :Prussian white; Prussian Blue Analogue; Sodium Ferrocyanide; Sodium Ion-battery; Recycling of batteries; Recycling of cathode materials;

   Sammanfattning : The aim of this project was to find a recycling route for Prussian white. During the experimental part, one recycling method was tested using sodium hydroxide and from this a method for re-synthesis of Prussian white was conducted as well as a method for re-crystallisation of sodium ferrocyanide.
