Nondestructive Analysis of Commercial Batteries.

Electrochemical batteries play a crucial role for powering portable electronics, electric vehicles, large-scale electric grids, and future electric aircraft. However, key performance metrics such as energy density, charging speed, lifespan, and safety raise significant consumer concerns. Enhancing battery performance hinges on a deep understanding of their operational and degradation mechanisms, from material composition and electrode structure to large-scale pack integration, necessitating advanced characterization methods.

Effects of catholyte aging on high-nickel NMC cathodes in sulfide all-solid-state batteries.

Sulfide solid-state electrolytes (SSEs) in all-solid-state batteries (SSBs) are recognized for their high ionic conductivity and inherent safety. The LiNiMnCoO (NMC811) cathode offers a high thermodynamic potential of approximately 3.8 V Li/Li and a theoretical specific capacity of 200 mA h g.

Solvent-mediated oxide hydrogenation in layered cathodes.

Self-discharge and chemically induced mechanical effects degrade calendar and cycle life in intercalation-based electrochromic and electrochemical energy storage devices. In rechargeable lithium-ion batteries, self-discharge in cathodes causes voltage and capacity loss over time. The prevailing self-discharge model centers on the diffusion of lithium ions from the electrolyte into the cathode.

Critical Contribution of Imbalanced Charge Loss to Performance Deterioration of Si-Based Lithium-Ion Cells during Calendar Aging.

Increasing the energy density of lithium-ion batteries, and thereby reducing costs, is a major target for industry and academic research. One of the best opportunities is to replace the traditional graphite anode with a high-capacity anode material, such as silicon. However, Si-based lithium-ion batteries have been widely reported to suffer from a limited calendar life for automobile applications.

Zinc Therapy Is a Reasonable Choice for Patients With Pressure Injuries: A Systematic Review and Meta-Analysis.

The aim of this systematic review was to summarize the evidence on the efficacy of zinc supplementation in patients with pressure injuries (PIs). Electronic data bases (Embase, MEDLINE, and Web of Science) were searched from inception to 2019 for randomized controlled trials (RCTs) and non-RCTs addressing the efficacy of zinc supplementation compared with a control nutrition invention on PI outcomes. The primary study outcome was the healing rate of PIs during treatment; the secondary outcomes were the improvement of PI area and pressure ulcer scale for healing (PUSH) score.

The relationship between pressure injury complication and mortality risk of older patients in follow-up: A systematic review and meta-analysis.

Pressure injuries (PIs) have now become a common complication of the elderly patients. Some studies have observed that pressure injuries may increase mortality, but this area of evidence has not been evaluated and summarised.
