Advances in lithium—sulfur batteries [PDF]

Materials Science and Engineering: R: Reports, 2017
This review is focused on the state-of-the-art of lithium-sulfur batteries. The great advantage of these energy storage devices in view of their theoretical specific capacity (2500 Wh kg−1, 2800 Wh L−1, assuming complete reaction to Li2S) has been the motivation for a huge amount of works.

Surface-engineered polymer brush gate electrodes enable high-sensitivity label-free glucose detection via organic electrochemical transistor

Sensors and Actuators Reports
Non-enzymatic glucose detection remains challenging due to poor selectivity and instability in complex biological environments. Here, we developed an organic electrochemical transistor (OECT) incorporating a CH2Cl2-derived poly(EDOT-FPBA) gate to enhance

Cathode porosity is a missing key parameter to optimize lithium-sulfur battery energy density

Nature Communications, 2019
While high sulfur loading has been pursued as a key parameter to build realistic high-energy lithium-sulfur batteries, less attention has been paid to the cathode porosity, which is much higher in sulfur/carbon composite cathodes than in traditional ...

Kinetic activation of interfacial Li2S via zirconia membrane reactor confinement catalysis for high‐performance lithium/sulfur batteries

InfoMat
The slow kinetics and irreversibility of Li2S deposition and dissolution during the sulfur reduction/evolution reactions (SRR/SER) hinder the fast‐charging and high‐rate capabilities of lithium–sulfur (Li/S) batteries.
