Li2MnSiO4 Nanostructured Cathodes for Rechargeable Lithium-Ion Batteries

Rechargeable lithium-ion battery technology dominates the portable electronics market following the rapid growth in demand since the introduction of the first, commercial lithium-ion battery by Sony in 1990 [1]. Motivated by concerns for global warming and environmental degradation, researchers have focused on extending the use of rechargeable lithium-ion batteries to large-scale applications. ...

Promising Candidates for Lithium Ion Batteries: High Nickel Lithium-Rich Layered Cathode Nanomaterial

Over the past decade, much attention has been paid to the development of lithium-ion batteries (LIBs) owing to the increasing demand for power sources with higher energy and power density. LiCoO2 has been one of the most widely used cathode materials for its easy synthesis and excellent reversibility since the commercialization of LIBs. However, LiCoO2 also suffers from many drawbacks such as h...

High‐Performance Heterostructured Cathodes for Lithium‐Ion Batteries with a Ni‐Rich Layered Oxide Core and a Li‐Rich Layered Oxide Shell

The Ni-rich layered oxides with a Ni content of >0.5 are drawing much attention recently to increase the energy density of lithium-ion batteries. However, the Ni-rich layered oxides suffer from aggressive reaction of the cathode surface with the organic electrolyte at the higher operating voltages, resulting in consequent impedance rise and capacity fade. To overcome this difficulty, we present...

Gas–solid interfacial modification of oxygen activity in layered oxide cathodes for lithium-ion batteries

Lattice oxygen can play an intriguing role in electrochemical processes, not only maintaining structural stability, but also influencing electron and ion transport properties in high-capacity oxide cathode materials for Li-ion batteries. Here, we report the design of a gas-solid interface reaction to achieve delicate control of oxygen activity through uniformly creating oxygen vacancies without...

Understanding structural defects in lithium-rich layered oxide cathodes

Planar defects in lithium-rich layered oxides were examined by aberration-corrected scanning transmission electron microscopy (STEM) to understand their formation. Planar defects were found to form during the transition of the transition metal layer from a disordered R 3m state to a lithiumordered C2/m state. This disorder-to-order transition resulted in three orientation variants, namely [100]...
