Mitigating Electrochemical Isolation in Ni-Rich Layered Cathodes for Durable Solid-State Batteries. [PDF]

Adv Sci (Weinh)
Electrochemical isolation of Ni‐rich layered cathodes in sulfide solid‐state batteries is uncovered as a previously unrecognized but critical performance‐limiting pathway. This study elucidates its origin and impact and introduces a scalable mitigation strategy using oxygen‐functionalized conductive carbon.

NEXAFS multiple scattering calculations of KO₂ [PDF]

Journal of Synchrotron Radiation, 2001
Since many years the oxidation of alkali metals has being attracted much interest due to the catalytic properties of metal promoters and the simple electronic structure of alkali atoms. The alkali-oxides phase diagram indicates that the interaction of oxygen with alkali metals can lead to the formation of different atomic O2- ions and molecular O2

NEXAFS study of carbonate substituted bioapatite

Journal of Physics: Conference Series, 2021
Abstract The investigation of unique carbonate substituted bioapatite of Champsocephalus gunnari icefish jaw and skull bones was carried out using NEXAFS spectroscopy. It has been established that these bones contain the B-type carbonate substituted hydroxyapatit with a content [CO3]2- anion of about 0.79-3.07 wt.%.
