Laser‐Induced Coal‐Based Porous Graphene as Anode Toward Advanced Lithium‐Ion Battery

Advanced Science, EarlyView.
A one‐step laser‐induced strategy is reported to prepare porous graphene by utilizing bituminous coal as a precursor (LIG‐B). Laser irradiation transforms coal into graphene, with small molecules from the polymer separating, recombining in gas and forming 3D porous graphene upon quick gas release.

Layer‐By‐Layer Approach to Improve the Capacitance of Conducting Polymer Films

Advanced Electronic Materials, EarlyView.
This work describes the synthesis and characterization of a composite material based on poly(3,4‐ethylenedioxythiophene) (PEDOT) and poly(3,4‐ethylenedioxypyrrole) (PEDOP) deposited in a layer‐by‐layer approach. Due to the developed electroactive area coming from the presence of 3D nanostructures, PEDOT/PEDOP demonstrates superior areal capacitance ...
