  1. 1. 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
