Nickel-Rich and Lithium-Rich Layered Oxide Cathodes: Progress and Perspectives
TL;DR: Li-rich layered oxides have attracted much research interest as cathodes for Li-ion batteries due to their low cost and higher discharge capacities compared to those of LiCoO2 and LiMn2O4 as mentioned in this paper.
Journal ArticleDOI
Recent advances in the electrolytes for interfacial stability of high-voltage cathodes in lithium-ion batteries
TL;DR: In this article, the authors describe several challenges for the cathode (spinel lithium manganese oxide (LMO), lithium cobalt oxide (LCO), lithium nickel cobalt manganes oxide (NCM), spinel lithium ion ion oxide (SILO), and lithium-rich layered oxide (Li-rich cathode))-electrolyte interfaces and highlight the recent progress in the use of oxidative additives and highvoltage solvents in high-performance cells.
Journal ArticleDOI
Li- and Mn-rich layered oxide cathode materials for lithium-ion batteries: a review from fundamentals to research progress and applications
TL;DR: Li and Mn-rich layered oxides (LMRO) have drawn much attention for application as cathode materials for lithium-ion batteries due to their high energy density of over 1000 W h kg−1 as discussed by the authors.
Journal ArticleDOI
Tunable and robust phosphite-derived surface film to protect lithium-rich cathodes in lithium-ion batteries.
TL;DR: This investigation revealed that the TMSP-derived surface layer can overcome the significant capacity fading of the Li-rich cathode by structural instability ascribed to an irreversible phase transformation from layered to spinel-like structures.
Journal ArticleDOI
Non-flammable organic liquid electrolyte for high-safety and high-energy density Li-ion batteries
TL;DR: In this paper, a rational design of non-flammable carbonate-based organic liquid electrolyte to satisfy safety, energy density and performance simultaneously was proposed, which can achieve high voltage stability and high energy density.

Journal ArticleDOI
A review on electrolyte additives for lithium-ion batteries
TL;DR: In this article, a review of electrolyte additives used in Li-ion batteries is presented, which can be classified into five categories: solid electrolyte interface (SEI) forming improver, cathode protection agent, LiPF 6 salt stabilizer, safety protection agent and Li deposition improver.

Demonstrating Oxygen Loss and Associated Structural Reorganization in the Lithium Battery Cathode Li[Ni0.2Li0.2Mn0.6]O2
A. Robert Armstrong,Michael Holzapfel,Petr Novák,Christopher S. Johnson,Sun-Ho Kang,and Michael M. Thackeray,Peter G. Bruce +6 more
TL;DR: It is demonstrated directly, by in situ differential electrochemical mass spectrometry (DEMS), that O2 is evolved from such Mn4+ -containing compounds, Li-Mn-Ni-O compounds, which can, after O loss, store 200 mAhg(-1) of charge compared with 140mAhg (-1) for LiCoO(2).

Detailed Studies of a High-Capacity Electrode Material for Rechargeable Batteries, Li2MnO3−LiCo1/3Ni1/3Mn1/3O2
TL;DR: Electrochemical oxidation/reduction data show that simultaneous oxygen and lithium removal at the voltage plateau upon initial charge causes the structural rearrangement, including a cation migration process from metal to lithium layers, which is consistent with the mechanism proposed in the literature related to the Li-excess manganese layered oxides.
