  1. 1. The effect of material properties on PEM fuel cell catalysts on durable oxidation reduction activity

    University essay from KTH/Kemiteknik

    Author : Xiaoling Jiang; [2023]
    Keywords : PEM fuel cell; catalyst; ORR activity; particle size; degradation; PEM-bränslecell; katalysator; syrgasreduktionsaktivitet; partikelstorlek; åldring;

    Abstract : I detta examensarbete utforskas påverkan av partikelstorleken hos Pt-katalysatorer på kolbärare på syrereduktionen i polymerelektrolytmembran (PEM)-bränsleceller. Den elektrokemiskt aktiva ytarean, aktiviteten för syrereduktion och tillhörande degraderingshastigheter för de undersökta katalysatorerna beräknas och jämförs. READ MORE

  3. 2. 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

  4. 3. Electrochemical strategies to retrieve lost capacity in Li-ion batteries by reversed Li-trapping

    University essay from Uppsala universitet/Oorganisk kemi; Uppsala universitet/Strukturkemi

    Author : Christopher Thulin; [2023]
    Keywords : Electrochemistry; lithium trapping; lithium-ion battery; diffusion;

    Abstract : Since the transportation sector wants to move away from fossil fuels and become more dependen ton clean and green energy, the use of rechargeable batteries is a good solution. Lithium-based batteries work very well as rechargeable batteries in electric vehicles. READ MORE
