TL;DR: Li9.54Si1.74P1.44S11.7Cl0.6P3S12 as discussed by the authors showed that Li 9.54 Si 1.54P 1.74Si 1.44 S11.3 has high specific power that is superior to that of conventional cells with liquid electrolytes.

TL;DR: In this paper, a huge kinetic difference in olivine Li x MPO 4 (M = Fe,Mn) is demonstrated in a quantitative manner, and the current relaxation to the stepwise anodic overvoltage (chronoamperometry) is measured for the Li x FePO 4 and Li x MnPO 4 under identical extrinsic conditions, which are carefully controlled and confirmed using Rietveld refinement for the X-ray diffraction profiles, direct texture observation by scanning electron microscope, Brunauer-Emmett-Teller surface area measurements,

TL;DR: It is demonstrated that the suppression of formation of superoxide-like species on lithium extraction results in reversible redox for oxide ions, which is stabilized by the presence of relatively less covalent character of Mn4+ with oxide ions without the sacrifice of electronic conductivity.

TL;DR: In this paper, the authors show that the solid solution maintained a layered rock-salt structure until x=0.25 and showed that iron and cobalt were in high-spin and low-spin configurations, respectively.

TL;DR: In this paper, phase relationships, structures, magnetic properties, and phase transitions in the lithium manganese oxide spinel were studied based on a wide variety of samples synthesized at temperatures over a range of 750 ≤======)| t====== ]-≤ 900 °C with Li/Mn ratios between 0.5 and 0.55 and various starting materials.
