1. 6. 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
