  1. 1. Towards Affordable Sodium-Ion Batteries : Mechanochemical Synthesis and Electrochemical Assessment of Iron-Based Fluorophosphate Cathode Material

    University essay from KTH/Materialvetenskap

    Author : Ratna Juwita; [2023]
    Keywords : Sodium-ion batteries; electrical energy storage EES ; iron oxide; positive electrode; material characterization; electrochemical; discharge capacity.; Natriumjonbatterier; elektrisk energilagring EES ; järnoxid; positiv elektrod; materialkarakterisering; elektrokemisk; urladdningskapacitet;

    Abstract : An urgent transformation from fossil fuels to cleaner energy sources to combat climate change has led to the utilization of renewable energies like solar, wind, and tidal power. However, the intermittency of these sources hinders their wider implementation. To address this, large-scale electrical energy storage (EES) systems are needed. READ MORE

  3. 2. Polymeric single Li+-ion conductors: preparation and characterisation

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Hannes Nederstedt; [2016]
    Keywords : single ion conductors; electrolytes; polymers; lithium ion batteries; polymer technology; polymerteknologi; Chemistry; Technology and Engineering;

    Abstract : Lithium-ion batteries are a common type of light-weight, rechargeable batteries. There are safety concerns because these batteries typically use an organic solvent electrolyte which presents fire hazards. By using dry polymer electrolytes, the fire hazards can be eliminated.

  4. 3. Fabrication and evaluation of nickel containing nanofibres for solid oxide fuel cell anodes using electrospinning technique

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Ida Fransson; Tara Larsson; [2016]
    Keywords : Solid oxide fuel cell; 8YSZ; Ni; electrospinning; renewable energy; Technology and Engineering;

    Abstract : The energy demand of the world continues to increase, while world's resources are exploited over its capacity. One way of facing these demands is to extend the use of fuel cells. A fuel cell converts chemical energy into electrical energy through a series of chemical and electrochemical reactions. READ MORE

  5. 4. Patterning of Highly Conductive Conjugated Polymers for Actuator Fabrication

    University essay from Linköpings universitet/Biosensorer och bioelektronik

    Author : Daniel Falk; [2015]
    Keywords : Biosensors; Bioelectronics; Microactuators; Conjugated polymers; Polypyrrole; PEDOT; Soft Lithography; Microcontact printing; Vapor phase polymerization; Drop-on-Demand printing; Photolithography; Lift-off;

    Abstract : Trilayer polypyrrole microactuators that can operate in air have previously been developed. They consist of two outer layers ofthe electroactive polymer polypyrrole (PPy) and one inner layer of a porous poly(vinylidene flouride) (PVDF) membranecontaining a liquid electrolyte. READ MORE

  6. 5. A microtechnology-based sensor system for deepwater analysis from a miniaturized submersible

    University essay from Ångström Space Technology Centre (ÅSTC)

    Author : Katarina Smedfors; [2010]
    Keywords : CTD; MEMS; microtechnology; sensors; thin film metallization; microelectrodes;

    Abstract : The aim of this master thesis has been to design, and partly manufacture and evaluate, a highly miniaturized, on-chip conductivity-temperature-depth (CTD) sensor system for deepwater analysis also including electrodes for pH and chloride ion concentration measurements. The microtechnology-based sensor system will be a vital instrument onboard the Deeper Access, Deeper Understanding submersible, which will be small enough for deployment through bore holes into the subglacial lakes of Antarctica.
