Prospects, challenges, and latest developments in lithium–air batteries
Naveed Akhtar,Waheed Akhtar +1 more
TL;DR: Li et al. as discussed by the authors evaluated the recent developments, and the inferences have been analyzed from the practical/commercial point of view, concluding that low discharge rate, lower number of cycles, oxidation of lithium anode, discharge products at the cathode, and side reactions inside the battery are the key limiting factors in the slow progress of Li-air batteries on an industrial scale.

Conductivity, charge transfer and transport number—an ac-investigation of the polymer electrolyte LiSCN-poly(ethyleneoxide)
TL;DR: In this paper, a series of impedance measurements in the frequency range 10−4−2 × 105 Hz and in the temperature range 20-170°C is reported for the cell: Li-metal/LiSCN [dissolved in poly (ethyleneoxide)]/Li-metal On the basis of the measurements a whole range of electrical properties such as the conductivity, the charge transfer resistance, the transport number for the Li+-ion, the double layer capacity and the dielectric constant were determined for the polymer complex.
