Design of electrolyte solutions for Li and Li-ion batteries: a review
This paper reviews approaches to the design of advanced electrolyte solutions for Li and Li-ion batteries. Important challenges are wide electrochemical windows, a wide temperature range ofExpand
An analysis of rechargeable lithium-ion batteries after prolonged cycling
Abstract We report herein on extensive post-mortem analysis of rechargeable Li-ion batteries after prolonged cycling at 25 and 40 °C. The 18650-type batteries produced by standard procedure at LGExpand
Effect of Li2CO3 additive on gas generation in lithium-ion batteries
Abstract To elucidate the mechanism of gas generation during charge–discharge cycling of a lithium-ion cell, the generated gases and passive films on the carbon electrode are examined by means of gasExpand
Studies of cycling behavior, ageing, and interfacial reactions of LiNi0.5Mn1.5O4 and carbon electrodes for lithium-ion 5-V cells
The cycling and storage behavior of LiNi 0.5 Mn 1.5 O 4 and MCMB electrodes for 5-V Li-ion batteries was investigated at elevated temperatures using a variety of electrochemical (CV, EIS) andExpand
On the capacity fading of LiCoO2 intercalation electrodes:: the effect of cycling, storage, temperature, and surface film forming additives
Abstract The electrochemical behavior and surface chemistry of LiCoO 2 intercalation cathodes as a function of cycling and storage at 25, 45, and 60 °C was studied. The standard solutions for thisExpand
SEI layer-forming additives for LiNi0.5Mn1.5O4/graphite 5 V Li-ion batteries
Abstract This study demonstrates that proper SEI layer on graphite anode is essential in LiNi 0.5 Mn 1.5 O 4 (LNMO)/graphite 5 V lithium-ion batteries. Succinic anhydride (SA) and 1,3-propane sultoneExpand
Two-band superconductivity in MgB2.
The study of the anisotropic superconductor MgB2 using a combination of scanning tunneling microscopy and spectroscopy reveals two distinct energy gaps with both gaps vanishing at the bulk T(c) with the data confirming the importance of Fermi-surface sheet dependent superconductivity proposed in the multigap model.

Determination of the oxidation potentials of organic benzene derivatives: theory and experiment
Abstract We have calculated the IP, Δ G e , and E ox values for 10 mono -substituted benzene molecules and compared them with experimental values obtained by linear sweep voltammetry. The E ox valuesExpand
Correlation between electrical resistivity and optical transmittance of Mg- and Ga-doped ZnO window layers in NIR-IR region and its effect on current density of kesterite solar cells
Abstract The doping of Mg and Ga into ZnO is a method for obtaining excellent optical and electrical properties for a window layer in an inorganic solar cell. Because a tradeoff exists between theExpand
Energy gap, penetration depth, and surface resistance of MgB(2) thin films determined by microwave resonator measurements
We have measured the temperature dependence of the microwave surface impedance Z(s)=R(s)+iomegamu(0)lambda of two c-axis oriented MgB(2) films employing dielectric resonator techniques. TheExpand
