Summary: Inkjet-printed conductive polymer PEDOT:PSS films have been developed as stretchable transparent electrodes in optoelectronic devices. By printing a formulated ink containing PEDOT:PSS, formamide, d-sorbitol, sodium dodecyl benzene sulfonate, and ethylene glycol, a uniform film with high conductivity and mechanical performance is achieved. The film shows a high conductivity of 1050 S/cm, sheet resistance of less than 145 omega/sq, and can maintain stability even after 200 cycles of stretching at 55% strain. The enhanced conductivity is due to the conformational transition of the backbone through secondary doping and post-treatment with formamide, as well as the removal of excess PSS components after phase separation.

Summary: The ongoing research on printed and flexible electronics is mainly focused on conductive 3D print patterning. However, the nonhomogeneous distribution of conductive elements in a polymer matrix and their tendency to shrink lead to low printing accuracies and poor mechanical and electrical properties. This study introduces a conductive ink for 3D printing by reinforcing poly(vinyl butyral-co-vinyl alcohol-co-vinyl acetate) with microwave-exfoliated graphene, which significantly enhances the electrical conductivity, tensile strength, and printing accuracy of the patterns. The printed conductive patterns show high flexibility suitable for wearable electronics and enable multifunctional electronic operations such as photoinduced heating, temperature sensing, and motion sensing, potentially paving the way for smart wearable electronics in healthcare and soft robotics.

Summary: This paper explored the thermoelectric properties of Cu2S films and found that the conductivity of the films can be enhanced by forming a superconducting layer on the surface of Cu2S, but the Seebeck coefficient decreases due to the large bandgap difference between the two materials. The film prepared with a content ratio of Cu2S and PEDOT:PSS of 1:1.2 exhibited the best thermoelectric performance. Furthermore, a flexible thermoelectric generator was constructed, which can provide continuous self-powered monitoring.

Summary: This article presents the results of a systematic study on the electrochemical performance and mechanical changes in two types of commercial batteries with different anode chemistry. The study reveals that the swelling of anode layers in batteries with silicon-based components causes deformations in the jelly roll structure, but the presence of a small percentage of silicon does not significantly impact the cycling performance of the cells within the relevant state-of-health range for electric vehicles (EVs). The research suggests that there is room for improving the cell capacities by increasing the silicon loading in composite anodes to meet the increasing demands on EVs.

Summary: An efficient phase inversion-impregnation approach is developed to fabricate BaO-decorated Ni8 mol% YSZ anode-supported tubular solid oxide fuel cells (SOFCs) with anti-coking properties. BaO nanoislands are successfully introduced inside the Ni-YSZ anode, leading to higher peak power densities and improved stability in methane fuel. Density functional theory calculations suggest that the loading of BaO nanoislands facilitates carbon elimination by capturing and dissociating H2O molecules to generate OH.

Summary: By coupling electrochemical testing to operando synchrotron based X-ray absorption and powder diffraction experiments, blended positive electrodes consisting of LiMn2O4 spinel (LMO) and layered LiNi0.5Mn0.3Co0.2O2 (NMC) were studied to understand their redox mechanism. It was found that blending NMC with LMO can enhance energy density at high rates, with the blend containing 25% LMO showing the best performance. Testing with a special electrochemical setup revealed that the effective current load on each blend component can vary significantly from the nominal rate and also changes with SoC. Operando studies allowed monitoring of the oxidation state evolution and changes in crystal structure, in line with the expected behavior of individual components considering their electrochemical current loads.
