Boron and fluorine Co-doped laser-induced graphene towards high-performance micro-supercapacitors

Carbon, Год журнала: 2023, Номер 212, С. 118101 - 118101

Laser-induced graphene (LIG) has attracted extensive research as an electrode material for micro-supercapacitors (MSC). However, the low capacitive performance of LIG arising from both limited specific surface area and few active sites remains challenging. Herein, in situ doping fluorine boron atoms into laser-induced was innovatively achieved via laser direct writing approach using boron-doped fluorinated polyimide (FB-PI) precursor. The porous co-doped (FB-LIG) exhibits more improved wettability significantly enhanced due to synergistic effect co-doping. By tuning weight ratio fluorine, MSC utilizing FB-LIG poly(vinyl alcohol) (PVA)/H2SO4 gel electrolyte delivers a high areal capacitance 49.81 mF/cm2 at current density 0.09 mA/cm2, 23 times higher that commercial (PI)-based LIG, 3 PI-based LIG. In addition, MSCs possess excellent mechanical stability flexibility, rendering them promising flexible wearable microelectronics.

Experimental design of paraffin/methylated melamine-formaldehyde microencapsulated composite phase change material and the application in battery thermal management system

Journal of Material Science and Technology, Год журнала: 2023, Номер 169, С. 124 - 136

Опубликована: Июль 19, 2023

In order to maintain the optimal operating temperature of battery surface and meet demand for thermal storage technology, management system based on phase change materials has attracted increasing interest. this work, a kind core-shell structured microcapsule was synthesized by an in-situ polymerization, where paraffin used as core, while methanol applied modify melamine-formaldehyde shell reduce toxicity improve stability. Moreover, three different types heat conductive fillers with same content 10 wt.%, i.e., nano-Al2O3, nano-ZnO carbon nanotubes were added, generating composites. The microcapsules uniform, not affected fillers, which evenly dispersed around. composite sample (10 wt.%) showed highest conductivity 0.50 W/(m K) latent 139.64 J/g. Furthermore, according leakage testing charge/discharge experiments, compared Al2O3 ZnO, addition remarkably enhances ability from 126.98 J/g prepared 125.86 one then J/g, well dissipation performance cooling effect decreasing 2% 12% microcapsule, presents broad application prospect in energy field.
