Electron-pinned defect dipoles in (Li, Al) co-doped ZnO ceramics with colossal dielectric permittivity

, 2020
This journal is © The Royal Society of Chemistry. Through systematic optimization studies of Li and Al co-doped ZnO ceramics we demonstrate that colossal permittivity with low dielectric loss (ϵr = 9862 and tan δ = 0.159 at the frequency of 1 kHz) at ...

Showcasing the Structure and Properties of Lanthanide‐Doped BaTiO3

Advanced Physics Research, Volume 4, Issue 9, September 2025.
Understanding the defect chemistry of Ln‐doped BTO, as well as the distribution of Ln ions inside the BTO host, is a challenge in the study of functional perovskite oxides. It provides important insights into the future development of Ln‐doped BTO materials, particularly in the context of low‐carbon transition strategies and renewable technologies that

Functional Electrolyte Additives: A Pinch of Salt/Solvent to an Electrolyte for High Energy Density Lithium‐Ion and Lithium–Metal Batteries

Small, Volume 21, Issue 34, August 28, 2025.
Electrolytes, often termed as the “blood” of battery play a decisive role in determining their performance metrics. This review thoroughly analyzes the role of functional electrolyte additives improving the performance and safety of Li‐ion/Li–metal batteries involving film formation, overcharge control, wide temperature and voltage operation ...
