Journal ArticleDOI
Heuristic solution for achieving long-term cycle stability for Ni-rich layered cathodes at full depth of discharge
Un Hyuck Kim,Geon Tae Park,Byoung Ki Son,Gyeong Won Nam,Jun Liu,Jun Liu,Liang-Yin Kuo,Payam Kaghazchi,Chong Seung Yoon,Yang-Kook Sun +9 more
TL;DR: Li[Ni0.90Co0.09Ta0.01]O2 as discussed by the authors is a Ni-rich layered oxide cathode that exhibits outstanding long-term cyclability and high energy at full depth of discharge in full cells.
Journal ArticleDOI
Extracting maximum capacity from Ni-rich Li[Ni0.95Co0.025Mn0.025]O2 cathodes for high-energy-density lithium-ion batteries
TL;DR: The electrochemical properties of Li[Ni0.95Co0.025Mn 0.025]O2 were evaluated to test whether the beneficial effect of Co and Mn addition persists at this extremely Ni-rich layered Li[NixCoyMn1−x−y] O2 (NCM) cathode as mentioned in this paper.
Journal ArticleDOI
Self-Passivation of a LiNiO2 Cathode for a Lithium-Ion Battery through Zr Doping
Chong Seung Yoon,Un Hyuck Kim,Geon Tae Park,Suk Jun Kim,Kwang Ho Kim,Jaekook Kim,Yang-Kook Sun +6 more
TL;DR: Li et al. as mentioned in this paper proposed a self-passivating Li2ZrO3 layer with a thickness of 5-10 nm, which uniformly encapsulates the surfaces of LiNiO2 cathode particles, is spontaneously formed by introducing excess Zr (1.4 atom %).
Journal ArticleDOI
Suppressing detrimental phase transitions via tungsten doping of LiNiO2 cathode for next-generation lithium-ion batteries
TL;DR: In this paper, a series of W-doped LiNiO2 cathodes were synthesized to systematically investigate the stabilization effect of W doping and showed that W doping prolonged the deleterious phase transition to the extent that the two-phase reaction (H2 → H3) merged into a single phase; thus, the phase transition proceeded through a solid-solution-like reaction.
Journal ArticleDOI
