High-Power Lithium Batteries from Functionalized Carbon Nanotube Electrodes

TL;DR: Layer-by-layer techniques are used to assemble an electrode that consists of additive-free, densely packed and functionalized multiwalled carbon nanotubes, which had a gravimetric energy approximately 5 times higher than conventional electrochemical capacitors and power delivery approximately 10 timesHigher than conventional lithium-ion batteries.
Journal ArticleDOI

High-power lithium batteries from functionalized carbon-nanotube electrodes

TL;DR: In this article, layer-by-layer techniques are used to assemble an electrode that consists of additive-free, densely packed and functionalized multi-walled carbon nanotubes, which can store lithium up to a reversible gravimetric capacity of approximately 200 mA h g(-1) while also delivering 100 kW kg(electrode) of power and providing lifetimes in excess of thousands of cycles.
Journal ArticleDOI

Lithium–oxygen batteries: bridging mechanistic understanding and battery performance

TL;DR: In this article, the authors show that the kinetics of oxygen reduction reaction are influenced by catalysts at small discharge capacities, but not at large Li2O2 thicknesses, yielding insights into the governing processes during discharge.
Journal ArticleDOI

All-carbon-nanofiber electrodes for high-energy rechargeable Li–O2 batteries

TL;DR: In this paper, hollow carbon fibers with diameters on the order of 30 nm were grown on a ceramic porous substrate, which was used as the oxygen electrode in Li-O2 batteries.
Journal ArticleDOI

Influence of Li2O2 morphology on oxygen reduction and evolution kinetics in Li–O2 batteries

TL;DR: In this article, two characteristic Li2O2 morphologies are formed in carbon nanotube (CNT) electrodes in a 1,2-dimethoxyethane (DME) electrolyte: discs/toroids (50-200 nm) at low rates/overpotentials (10 mA gC−1 or E > 2.7 V vs. Li), or small particles (<20 nm), while discs exhibit a sloping profile with low overpotential (<4 V).
