Summary: Counter electrodes (CEs) for dye-sensitized solar cells (DSSC) were fabricated using poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate (PEDOT:PSS) and platinum (Pt) solution, with high transparency and adhesion on an FTO glass substrate, through the Marker pen lithography coating method. The morphology and roughness of the PEDOT:PSS-MPL and Pt-MPL CEs were analyzed using scanning electron microscopy (SEM) and atomic force microscopy (AFM), while the electrochemical properties were evaluated using electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV). The device performance was assessed through current density-voltage (J-V) measurements, with the Pt-MPL and PEDOT:PSS-MPL CEs achieving power conversion efficiencies (PCE) of 4.25% and 3.00%, respectively, compared to dip coated PEDOT:PSS-DC and Pt-DC CEs.

Summary: LiNixCoyMn1-x-yO2 (NCM) is a critical cathode material for lithium-ion batteries in electric vehicles. The aging of cathode/electrolyte interfaces leads to capacity degradation and long-term cycle instability. A novel neural network model called ACGNet is developed to predict electrochemical stability windows of crystals, allowing for high-throughput screening of coating materials. LiPO3 is identified as a promising coating material with high oxidation voltage and low cost, which significantly improves the cycle stability of NCM batteries. This study demonstrates the accuracy and potential of machine learning in battery materials.

Summary: In this study, a bifunctional electrode host design consisting of carbon nanofibers implanted ordered porous Co-decorated Al2O3 supported on carbon nanotube film (CNTF) was proposed to address the shuttling effect of lithium polysulfides (LiPSs) and dendrite formation of metal lithium anode in lithium-sulfur (Li-S) batteries. The electrode exhibited excellent conductivity, efficient confinement of LiPSs, and catalytic conversion performance, resulting in high initial capacity and good capacity retention during cycling. As an anode, the electrode showed excellent Li+ diffusion performance and uniform lithium growth behavior, achieving a dendrite-free lithium electrode. The flexible pack cell assembled from these electrodes delivered a specific capacity of 972 mAh g(-1) with good capacity retention.
