TL;DR: The proposed all-polymer solar cells have even better performance than the control polymer-fullerene devices with phenyl-C61-butyric acid methyl ester as the electron acceptor and exhibit dramatically enhanced strength and flexibility compared with polymer/PCBM devices.

TL;DR: The strengthening mechanism of the RGO is investigated by a double cantilever beam test using the graphene/Cu model structure and the yield strength of the 2.5 vol% RGO/Cu nanocomposite is 1.8 times higher than that of pure Cu.

TL;DR: The unique wetness-resistant adhesion provided by the catechol groups allows the silicon nanoparticle electrodes to maintain their structure throughout the repeated volume expansion and shrinkage during lithiation cycling, thus facilitating substantially improved specific capacities and cycle lives of lithium-ion batteries.

TL;DR: In this article, a flexible transparent electrode was fabricated on a non-flat surface to demonstrate the possibility of cost-effective mass production as well as the applicability to the unconventional arbitrary soft surfaces.

TL;DR: This work revisits the key components of the battery (current collector, binder, and separator) and replaces them with the materials that support robust mechanical endurance of the lithium rechargeable battery.
