1. 1. On the stability of current collectors in high-voltage lithium-ion batteries containing LiFSI electrolytes

   University essay from Uppsala universitet/Oorganisk kemi

   Author : Kevin Carlö; [2023]
   Keywords : LiFSI; high-voltage; anodic dissolution; corrosion; aluminum; current collector; electrolyte; battery;

   Abstract : The increasing energy demand requires a transition from fossil fuels to renewable resources. Lithium-ion batteries (LIBs) offer a promising solution as efficient energy storage devices. However, the aluminum current collector (CC) in LIBs is susceptible to anodic dissolution above 3 V vs. READ MORE

3. 2. Corrosion initiation induced by sodium sulfate and sodium chloride particles on Cu and the golden alloy Cu5Al5Zn at simulated atmospheric conditions

   University essay from KTH/Materialvetenskap

   Author : Weijie Zhao; [2017]
   Keywords : atmospheric corrosion; sodium sulfate; sodium chloride; Cu5Al5Zn; Cu metal; mixed salt pre-deposition; laboratory exposure; LOM; SEM EDS; ATR-FTIR; cathodic reduction;

   Abstract : Effects of sodium sulfate (Na2SO4) particle deposition on the atmospheric corrosion of copper (Cu) metal and a Cu-based alloy (Cu5Al5Zn) used in architectural applications were investigated at laboratory conditions compared with effects induced by sodium chloride (NaCl) and to some extent ammonium sulfate (NH4)2SO4 induced corrosion. Pre-deposited surfaces were exposed to repeated wet/dry conditions in a climatic chamber and the formation of corrosion products were assessed using light optical microscopy (LOM), scanning electron microscopy with elemental analysis (SEM/EDS), Fourier transform infrared techniques (FTIR microscopy) and cathodic reduction (CR).
