TL;DR: Oxygen-redox-based Li-rich layered oxide cathode materials always suffer from severe voltage decay, because of progressively structural transformation as mentioned in this paper, and the initial consensus is that less utilization...

TL;DR: In this article, a 1.6-V flexible, aqueous asymmetric microsupercapacitor (AMSC) with 83% capacitance retention after 5000 cycles was designed by the integration and voltage balance of functionalized graphene-based cathode as double-layer supercapacitive electrode and iodine-doped graphene anode as a pseudocapacive electrode.

TL;DR: In this article, layered lithium-excess materials Li1+xNi0.3Co0.2O2+δ were synthesized by a coprecipitation method and the effects of lithium content on the structure and electrochemical performance of these materials were evaluated by employing X-ray diffraction (XRD), inductive coupled plasma (ICP), scanning electron microscopy (SEM), electrochemical impedance spectroscopy (EIS) and galvanostatic charge/discharge tests.

TL;DR: Li-rich layered oxides can deliver ultra-high capacities which stem from a blend of cationic redox and mostly lattice oxygen redox as discussed by the authors, but the oxygen reaction often leads to structure transition and oxygen release from the material surface.

TL;DR: Graphene: Energy Storage and Conversion Applications as discussed by the authors describes the fundamentals and cutting-edge applications of graphene-based materials for energy storage and conversion systems and provides an overview of recent advancements in specific energy technologies.
