TL;DR: This work shows a novel mechanism that can fundamentally alter dendrite formation in lithium-ion batteries as well as other metal batteries and transform the surface uniformity of coatings deposited in many general electrodeposition processes.

TL;DR: It is demonstrated that a novel air electrode consisting of an unusual hierarchical arrangement of functionalized graphene sheets (with no catalyst) delivers an exceptionally high capacity of 15000 mAh/g in lithium-O(2) batteries which is the highest value ever reported in this field.

TL;DR: In this paper, a review article summarizes the recent research progress on the synthesis of nanostructured carbon and its application in energy storage and conversion, and the common challenges in developing simple, scalable, and environmentally friendly synthetic and manufacturing processes, in controlling the nanoscale and high level structures and functions, and in integrating such materials with suitable device architectures are reviewed.

TL;DR: The observation of structure transition characteristics discussed in this paper provides direct explanation for the observed gradual capacity loss and poor rate performance of the layered composite and provides clues about how to improve the materials structure in order to improve electrochemical performance.

TL;DR: It is found the formation of the intragranular cracks is directly associated with high-voltage cycling, an electrochemically driven and diffusion-controlled process.
