    Abstract : Maritime transportation emits about 3% of global greenhouse gas, International Maritime Organization (IMO) aims to reduce shipping’s emissions by 50% with respect to 2008 levels. Proton exchange membrane fuel cells (PEMFCs) are considered among the most promising clean technologies for decarbonizing the maritime sector. READ MORE

  6. 5. Investigating Particle Cracking in Single- and Polycrystalline Nickel-Rich Cathodes using In Situ Impedance Spectroscopy

    University essay from Uppsala universitet/Strukturkemi

    Author : Mattias Sjödin; [2021]
    Keywords : Electrochemical surface area; particle cracking; NMC811; transmission-line model; equivalent-circuit fitting; commercial Li-ion batteries;

    Abstract : State-of-the-art Li-ion cathode materials are based on LiMO2 (M=Ni, Mn, Co) layered transition metal oxides (denoted NMC) with Ni-rich composition because of their high specific capacity. Yet, these materials suffer from poor capacity retention due to crack formation during de-/lithiation cycling. READ MORE
