Stress-relieving and electrically conductive single-walled carbon nanotubes (SWNTs) conjugated polymer, poly[3-(potassium-4-butanoate)thiophene] (PPBT), wrapped silicon microparticles (Si MPs) have been developed as a composite active material to overcome technical challenges such intrinsically low electrical conductivity, initial Coulombic efficiency, stress-induced fracture due severe volume changes of Si-based anodes for lithium-ion batteries (LIBs). The PPBT/SWNT protective layer...
To investigate the productivity laws of coalbed gas (CBG) wells in carbon dioxide (CO2)-rich coalfield, Haishiwan coal mine Yaojie Gansu Province, China, which is rich CO2 different concentrations CBG, was selected as study area. Using numerical simulation technology, production capacity CBG simulated, and thermodynamic factors influencing adsorption differences on were discussed. Numerical indicates that with increase concentration, breakthrough time prolonged, first increases then...
Abstract One focal area of contemporary organic mixed ionic‐electronic conductor (OMIEC) research relates to utilization dual‐conductive properties enhance the ion/electron transfer kinetics for energy storage applications. Insight regarding OMIEC response toward electrolyte anion and solvent used in lithium‐ion batteries (LIBs), however, is limited. Here, first time, solvent‐phobic ionophilic (SP‐IP) OMIEC, poly[3‐(potassium‐4‐butanoate)thiophene‐2,5‐diyl] (P3KBT), are revealed through...
The aggregation and crystallization of poly(3-hexylthiophene-2,5-diyl) (P3HT), a representative active layer material used for organic field-effect transistor (OFET) applications, are influenced by the solution pretreatment deposition process. This study explores vibration-assisted convective fabrication OFETs in comparison to spin coating, blade without vibration. ultraviolet-visible spectroscopic analysis demonstrates that deposition, especially assisted with vibration, leads greater...
Contemporary design principles for organic mixed ionic electronic conductors (OMIECs) are mostly based on the ethylene glycol moiety, which may not be representative of OMIEC class as a whole. Furthermore, glycolated polymers can difficult to synthesize and process effectively. As an emerging alternative, we present series polythiophenes functionalized with hybrid carboxyl-alkyl side chain. By variation alkyl spacer length, comprehensive evaluation both impact carboxylic acid...
Tailored side chains can improve structural stability, ion transport and capacity retention, offering a solution to key challenges such as fade electrode degradation in lithium-ion batteries.
Silicon is one of the most promising anode materials for next generation Lithium ion batteries (LIBs) on account its ultrahigh specific capacity (4200 mAh g -1 ) and relatively low working potential 0.3 V (vs. Li + /Li). However, practical commercial implementation silicon poses a great challenge due to technical difficulties such as conductivity (10 -5 -10 -3 S cm ), initial Coulombic efficiency (50-80%) stress-induced fracture, along with SEI accumulation severe volume changes (~400%)...
Abstract Organic mixed ionic‐electronic conductors (OMIECs) have garnered significant attention due to their capacity transport both ions and electrons, making them ideal for applications in energy storage, neuromorphics, bioelectronics. However, charge compensation mechanisms during the polymer redox process remain poorly understood, are often oversimplified as single‐ion injection with little counterion effects. To advance understanding design strategies toward next‐generation OMIEC...
