  1. 1. Organic Electrochemical Transistors : Materials and Challenges

    Författare :Silan Zhang; Simone Fabiano; Magnus Berggren; Jenny Nelson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The use of organic mixed ionic-electronic conductors (OMIECs) has demonstrated the potential to transform the field of bioelectronics, spanning from medical diagnostics to neuromorphic computing hardware. To keep up with the fast-paced demands, it is crucial to develop customizable device fabrication, design new materials, improve operation stability, and explore the ion-electron interactions within OMIECs.

  7. 5. Transient electrochemical methods for investigation of porous battery electrodes

    Författare :Anton Lundqvist; KTH; []
    Nyckelord :electrochemical iimpedance spectroscopy; limn2o4; mathematical modelling; metal hydride; mcroelectrode; porous electrode; potential step; state of charge;

    Sammanfattning : This thesis treats electrochemical methods used to studybattery materials. Two different types of materials are used asmodel systems in this study, metal hydride alloys used in thenickel-metal hydride battery and LiMn2O4suggested for use in the lithium-ion battery. Thetwo model systems are used to critically analyse differentexperimental methods. LÄS MER
