Article Synopsis
- * Recent advancements in GPE technology enhance battery performance, including better long-term stability and higher capacity, along with innovations like self-protection, thermotolerance, and self-healing features.
- * Despite these advancements, challenges remain, such as achieving better ionic conductivity at low temperatures and ensuring mechanical strength, with a focus on future research to tackle these issues, specifically for high-energy and thermally stable battery applications.
A solid-solution cathode of LiCoPO-LiNiPO was investigated as a potential candidate for use with the LiTiO (LTO) anode in Li-ion batteries. A pre-synthesized nickel-cobalt hydroxide precursor is mixed with lithium and phosphate sources by wet ball milling, which results in the final product, LiNiCoPO (LNCP) by subsequent heat treatment. Crystal structure and morphology of the product were analyzed by X-ray powder diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and scanning electron microscopy (SEM).

This phase transition is due to the fragile ionic bonding between the cationic and anionic parts of HPs during their formation. Herein, we report the synthesis of water-stable, red-light-emitting α-phase FAPbI nanocrystals (NCs) using five different amines to overcome these intrinsic phase instabilities.

Methods: Relevant randomised controlled trials evaluating mobile phone-based self-management interventions for medication adherence and/or change in blood pressure in coronary heart disease patients were identified by searching six electronic databases (PubMed, Cochrane, CINAHL, ProQuest, Scopus and EMBASE) from January 2008 to January 2019. The trials were screened, data were extracted and quality was assessed by two independent reviewers.
