Electrochemical double layer capacitors (EDLCs) are promising energy storage devices with high power densities and long cycle lives. (1,2) Nanoporous carbons, especially activated carbons, are the cheapest and most commonly used electrode materials in commercial EDLCs. (2) Such carbons consist of disordered graphene-like fragments containing defects. These fragments form the pore walls of porous three-dimensional structures with a distribution of pores sizes.

AbstractConducting polymers are mixed ionic–electronic conductors that are emerging candidates for neuromorphic computing, bioelectronics and thermoelectrics. However, fundamental aspects of their many-body correlated electron–ion transport physics remain poorly understood. Here we show that in p-type organic electrochemical transistors it is possible to remove all of the electrons from the valence band and even access deeper bands without degradation.

Improving Long-term Capacity Retention of NMC811 via Lithium Aluminate Coatings Using Mixed-metal Alkoxides Ni-rich LiNixMnyCozO2 (NMC) materials such as NMC811 (80% Ni) are promising Li-ion battery cathodes due to their high energy density and low cost. However, their reactive surfaces pose a practical challenge for their handling and storage, due to their fast degradation under operation or storage in ambient air.

AbstractHyperfluorescence shows great promise for the next generation of commercially feasible blue organic light-emitting diodes, for which eliminating the Dexter transfer to terminal emitter triplet states is key to efficiency and stability. Current devices rely on high-gap matrices to prevent Dexter transfer, which unfortunately leads to overly complex devices from a fabrication standpoint.
