1. 1. Building Sustainable Batteries : Organic electrodes based on Li- and Na-benzenediacrylate

   Författare :Alina Oltean; Daniel Brandell; Leif Nyholm; Steven Renault; Martin Sjödin; Robert Dominko; Uppsala universitet; []
   Nyckelord :Organic Electrode Materials; Li-ion Batteries; Na-ion Batteries; Calendaring; Recycling Process; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

   Sammanfattning : As possible alternatives to the conventional inorganic Li- or Na-ion battery electrode materials, organic compounds have recently drawn considerable attention. However, major challenges such as poor electronic conductivity, solubility in battery electrolyte or fast capacity decay of the resulting electrochemical cells are some of the reasons that hold these compounds back from becoming commercial solutions in the energy system.
