Electrostatic‐Attraction‐Driven Self‐Assembled Graphene‐Disordered Rocksalt Composite Cathode for Lithium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A non‐aqueous, solution‐based graphene‐wrapping strategy is shown to stabilize disordered rocksalt LMTOF cathodes without structural degradation. The graphene‐wrapped cathode suppresses oxygen loss and parasitic interfacial reactions, lowers impedance growth, and delivers improved cycling stability and rate capability compared with conventional ball ...

Review: on rare-earth perovskite-type negative electrodes in nickel–hydride (Ni/H) secondary batteries

open access: yesMaterials for Renewable and Sustainable Energy, 2017
Rare-earth perovskites-type oxides are compounds with the general formula ABO3. There are many industrial and research applications related to their properties such as photocatalytic activity, magnetism, or pyro-ferro and piezo-electricity, and interest ...

Mimicking Silent Synapse Recruitment: A SiOx/Cu‐Pancake Memristive Device For Analog Neuromorphic Computing

open access: yesAdvanced Functional Materials, EarlyView.
Electroforming‐free TiN/SiOx/Cu/SiOx/TiN memristive devices exploit pancake‐like Cu nanoparticles embedded in a SiOx double layer to create a heterogeneous Schottky‐barrier landscape. Under bias, oxygen‐vacancy redistribution progressively lowers local barriers and recruits initially inactive Cu‐PC pathways into a parallel conduction ensemble, enabling

Performance of lightweight nickel electrodes [PDF]

open access: yes, 1988
The NASA Lewis Research Center is currently developing nickel electrodes for nickel-hydrogen (Ni-H2) batteries. These electrodes are lighter in weight and have higher energy densities than the heavier state-of-the-art (SOA) sintered nickel electrodes. In
