Adv Mater 2018 Dec 5:e1805574. Epub 2018 Dec 5.

Science and Engineering Program and Texas Materials Institute, The University of Texas at Austin, Austin, TX, 78712, USA.

No single polymer or liquid electrolyte has a large enough energy gap between the empty and occupied electronic states for both dendrite-free plating of a lithium-metal anode and a Li extraction from an oxide host cathode without electrolyte oxidation in a high-voltage cell during the charge process. Therefore, a double-layer polymer electrolyte is investigated, in which one polymer provides dendrite-free plating of a Li-metal anode and the other allows a Li extraction from an oxide host cathode without oxidation of the electrolyte in a 4 V cell over a stable charge/discharge cycling at 65 °C; a poly(ethylene oxide) polymer contacts the lithium-metal anode and a poly(N-methyl-malonic amide) contacts the cathode. All interfaces of the flexible, plastic electrolyte remain stable with no visible reduction of the Li conductivity on crossing the polymer/polymer interface. Read More

The interfacial engineering plays an important role in enhancing the electrochemical properties of graphene-based hybrid materials for energy conversion and storage. Herein, we propose a facile interfacial engineering route for achieving a novel type of SnS/N-doped graphene (SnS/NG) composite with superior lithium storage capability. Interestingly, the SnS particles formed show two totally different morphologies including ultrasmall nanoparticles about 5 nm and ultrathin nanosheets, and they are strongly coupled with nitrogen-doped graphene, giving rise to a unique 0D/2D heterostructure.

Before Li Ion Batteries.

Chem Rev 2018 Nov 30. Epub 2018 Nov 30.

Electrochemistry Branch , U.S. Army Research Laboratory , Adelphi , Maryland 20783 , United States.

This Review covers a sequence of key discoveries and technical achievements that eventually led to the birth of the lithium-ion battery. In doing so, it not only sheds light on the history with the advantage of contemporary hindsight but also provides insight and inspiration to aid in the ongoing quest for better batteries of the future. A detailed retrospective on ingenious designs, accidental discoveries, intentional breakthroughs, and deceiving misconceptions is given: from the discovery of the element lithium to its electrochemical synthesis; from intercalation host material development to the concept of dual-intercalation electrodes; and from the misunderstanding of intercalation behavior into graphite to the comprehension of interphases.

Self-supporting TiCT foam/S cathodes with high sulfur loading for high-energy-density lithium-sulfur batteries.

Nanoscale 2018 Nov 30. Epub 2018 Nov 30.

School of Chemical Engineering and Energy, Zhengzhou University, Zhengzhou 450001, P. R. China.

Lithium-sulfur (Li-S) batteries, with high theoretical energy density, cost-effective preparation and environmental benignancy, have been deemed as new encouraging energy storage solutions. However, their development and applications are limited by their low practical energy density and rapid capacity fading. Herein, self-supporting Ti3C2Tx foam, as a novel sulfur host, was synthesized via direct stacking of Ti3C2Tx flakes into film followed by hydrazine-induced foaming. Read More

Nitrogen-Doped Carbon Nanotube Forest Planted on Cobalt Nanoflower as Polysulfide Mediator for Ultralow Self-Discharge and High Areal-Capacity Lithium-Sulfur Batteries.

Nano Lett 2018 Nov 30. Epub 2018 Nov 30.

Lithium-sulfur (Li-S) batteries with high theoretical energy density have caught enormous attention for electrochemical power source applications. However, the development of Li-S batteries is hindered by the electrochemical performance decay resulted from low electrical conductivity of sulfur and serious shuttling effect of intermediate polysulfides. Moreover, the areal capacity is usually restricted by the low areal sulfur loadings (1. Read More

Uniform Nucleation of Lithium in 3D Current Collectors via Bromide Intermediates for Stable Cycling Lithium Metal Batteries.

J Am Chem Soc 2018 Nov 29. Epub 2018 Nov 29.

Conductive framework is generating considerable interest for lithium metal anode to accommodate Li+ deposition, due to its ability of reducing electrode current density by increasing the deposition area. However, in most cases, the electroactive surface area is not fully utilized for the nucleation of Li in 3D current collectors, especially under high current densities. Herein, uniform nucleation of Li in conductive skeleton is achieved by two-step synergetic process arising from CuBr and Br-doped graphene-like film. Read More
