Unprecedented strong and reversible atomic orbital hybridization enables a highly stable Li-S battery.
The shuttle effect and excessive volume change of the sulfur cathode severely impede the industrial implementation of Li-S batteries. It is still highly challenging to find an efficient way to suppress the shuttle effect and...
DFT Simulation-Based Design of 1T-MoS2 Cathode Hosts for Li-S Batteries and Experimental Evaluation.
The main challenge in lithium sulphur (Li-S) batteries is the shuttling of lithium polysulphides (LiPSs) caused by the rapid LiPSs migration to the anode and the slow reaction kinetics in the chain of LiPSs conversion. In this...
Structure Prediction of Li--Sn and Li--Sb Intermetallics for Lithium-ion Batteries Anodes.
M Mayo, AJ Morris
Jul 04, 2017
A variety of new stable and metastable Li–Sn and Li–Sb intermetallics are presented using the ab initio random structure searching (AIRSS) and species swapping methods. There include LiSn2–P4/mmm, Li2Sn3–P-1, Li7Sn9–P42/n...
Lithium-ion conductivity in Li<sub>6</sub>Y(BO<sub>3</sub>)<sub>3</sub>
The development of new frameworks for solid electrolytes that exhibit fast Li-ion diffusion is critical for enabling new energy storage technologies. Here, we present a combined experimental and computational investigation into...
Mg<inf>x</inf>Mn<inf>2-x</inf>B<inf>2</inf>O<inf>5</inf> Pyroborates (2/3 ≤ x ≤ 4/3)
MgMnB2O5, Mg2/3Mn4/3B2O5, and Mg4/3Mn2/3B2O5 pyroborates have been prepared via a ceramic method. When charging MgMnB2O5 vs Li, all of the Mg2+ can be removed, and with subsequent cycles, 1.4 Li ions, corresponding to a capacity...

Quantitatively analyzing the failure processes of rechargeable Li metal batteries.
Practical use of lithium (Li) metal for high–energy density lithium metal batteries has been prevented by the continuous formation of Li dendrites, electrochemically isolated Li metal, and the irreversible formation of solid...
L q -spectra of self-affine measures
Abstract: We study L q -spectra of planar self-affine measures generated by diagonal matrices. We introduce a new technique for constructing and understanding examples based on combinatorial estimates for the exponential growth...

Excitonic Emission of Monolayer Semiconductors Near-Field Coupled to High-Q Microresonators.
We present quantum yield measurements of single layer WSe2 (1L-WSe2) integrated with high-Q ( Q > 106) optical microdisk cavities, using an efficient (η > 90%) near-field coupling scheme based on a tapered optical fiber....
CT/MRI LI-RADS v2018 vs. CEUS LI-RADS v2017-Can Things Be Put Together?
Different LI-RADS core documents were released for CEUS and for CT/MRI. Both documents rely on major and ancillary diagnostic criteria. The present paper offers an exhaustive comparison of the two documents focusing on the...

Existence and deformations of Kähler–Einstein metrics on smoothable Q-Fano varieties
In this article we prove the existence of Kähler–Einstein metrics on Q-Gorenstein smoothable, K-polystable Q-Fano varieties, and we show how these metrics behave, in the Gromov–Hausdorff sense, under Q-Gorenstein smoothings.
