1 Νοε 2022 · The Ni-rich layered oxides cathodes with low Li/Ni intermixing obtained by ion exchange at a low reaction temperature, where sodium-based layered oxides were used as precursors for ion exchange with Li + ion in lithium molten salts.
31 Οκτ 2022 · The results reveal that there is more oxygen release and lower initial temperature of phase transition with increasing of Ni contents. The effect between Li + vacancies and Ni 2+ raised Ni 3+ during Li +-deintercalation process can intensify oxygen loss, and form more NiO compounds in local coordination structure unit .
10 Ιουν 2019 · In this Account, we start by introducing the Ni/Li disordering in LiNiO 2, the experimental characterization of Ni/Li disordering, and analyzing the impact of Ni/Li disordering on electrochemical characteristics of layered TM oxides. The antisite Ni in the Li layer can limit the rate performance by impeding the Li ion transport.
1 Δεκ 2021 · When Li/Ni intermixing occurs, the activation energy of both diffusion paths is affected by steric effects and electrostatic interaction. With regard to steric effect, the concentration of Li vacancies decreases when Ni 2+ is present in the Li layer compared with without Li/Ni intermixing.
31 Οκτ 2017 · Using extensive ab initio calculations combined with experiments, here we report that a superexchange interaction between transition metals plays a dominating role in tuning the Ni/Li disordering in NMC materials.
19 Σεπ 2016 · Under this model, how the lithium content, valence states of Ni, contents of Ni, Mn, and Co, and Ni/Li disorder to tune the thermal stability of NMC materials by affecting the sites, content, and the release temperature of the most unstable oxygen is proposed.
15 Σεπ 2020 · Highlights. NiFe LDH/NiTe interface nanorod was built by forming NiFe LDH at the surface of NiTe nanorod. The binding strength of intermediates are optimized by electronic interaction of NiFe LDH and NiTe. The NiFe LDH/NiTe interface nanorods exhibit remarkable OER activity in 1.0 M KOH.
