“…These indirect transitions and Urbach tail features can be caused by the presence of disordered and/or impurity states causing energy gap transitions, likely caused by surface related absorption. 83,84 As such, Li/Na depletion at both the exposed surface and LLO interface of NVP/LVP coatings is at least partially responsible for lowering the CBM of NVP/LVP-LLO in comparison to PR-LLO. Despite this, the alterations in the electronic band structure of Li-rich layered oxide by VP coating proved benecial in both theory and practice.…”
With a specific energy density >250mAhg-1, Li-rich layered transition metal oxides (LLOs) are one of the most promising cathode materials for commercial higher energy density Lithium-ion batteries (LIBs). However, oxygen...

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
