Article Abstract
The aqueous iron ion batteries (AIIBs) are an attractive option for large-scale energy storage applications. However, the inadequate plating and stripping of Fe ions underscore the need to explore more suitable cathode materials. Herein, we optimize the structure of tunnel-like VO nanosheets by introducing Mn ion intercalation as a cathode material to enhance their performance in AIIBs. Mn serves as a stabilizing pillar for VO, which brings some oxygen vacancies to provide extra electrochemically active sites, and accelerates the reversible (de)insertion of Fe ions. In addition, the density functional theory (DFT) calculations show that the introduction of Mn reduces the band gap of VO and also decreases the electrostatic interaction between Fe and VO. Consequently, the VO with interlayer Mn pillars (5% MVO) electrodes exhibit a remarkable capacity of 284.32 mAh g at a current density of 0.1 A g and demonstrate excellent cycle life, maintaining 81.7% of their capacity at 1.0 A g after 600 cycles. Therefore, these results offer a promising choice for the cathode material to achieve outstanding electrochemical performance in AIIBs.

Vagus nerve stimulation (VNS) is a promising therapy for neurological and inflammatory disorders across multiple organ systems. However, conventional rigid interfaces fail to accommodate dynamic mechanical environments, leading to mechanical mismatches, tissue irritation, and unstable long-term interfaces. Although soft neural interfaces address these limitations, maintaining mechanical durability and stable electrical performance remains challenging.

The study addresses the critical issue of sepsis diagnosis, a life-threatening condition triggered by the body's immune response to infection that leads to mortality. Current diagnostic methods rely on the time-consuming assessment of multiple biomarkers by a series of tests, leading to delayed treatment. Here, we report a platform for developing a point-of-care (POC) device utilizing electrochemical immunosensors for the dual and rapid detection of sepsis biomarkers: Procalcitonin (PCT), Interleukin-6 (IL-6), and C-reactive protein (CRP) as host markers and lipopolysaccharide (LPS) as a pathogen marker.

LiNiMnO (LNMO) is a promising material for the cathode of lithium-ion batteries (LiBs); however, its high operating voltage causes stability issues when used with carbonate battery electrolytes. Ionic liquids are a viable alternative to conventional carbonate solvents due to their thermal stability and electrochemical window. This work reports the performance of LNMO/Li half cells with an ionic liquid electrolyte (ILE) composed of 0.

Organic battery electrode materials represent a sustainable alternative compared to most inorganic electrodes, yet challenges persist regarding their energy density and cycling stability. In this work, a new organic electrode material is described, which is obtained via ionothermal polymerization of low-cost starting materials, melem (2,5,8-triamino-tri-s-triazine) and perylenetetracarboxylic dianhydride (PTCDA). The resulting networked polymer Melem-PDI exhibits favorable thermal and electrochemical properties, prompting investigation into its performance as a positive electrode material in rechargeable lithium and magnesium batteries.

The rapid advancement of implantable medical electronic devices has spurred substantial research into implantable energy storage systems. However, the presence of multiple film resistors in traditional sandwich structures impedes further enhancements in the electrochemical performance of supercapacitors and may result in contact failures between electrodes and separators or catastrophic short-circuit failures during tissue deformation. This study introduces a novel approach for fabricating all-in-one Zn-ion hybrid supercapacitors, which effectively mitigates performance degradation and safety concerns arising from interfacial issues.
