Trapping Li polysulfides in a polymer matrix to improve Li-S battery performance

Green Car Congress

To overcome the challenge of soluble polysulfides as charge/discharge intermediates in Li-S batteries, researchers at the University of Texas at Austin, with colleagues at Murray State University, have designed highly crosslinked polymer-electrolyte coating layers with electron-donating groups to bind the polysulfides.

A New Energy-Efficient Hydrogel Pulls Water From Air

Cars That Think

Using a new kind of hydrogel material, researchers at the University of Texas at Austin have pulled water out of thin air at temperatures low enough to be achieved with sunlight. The material is a hydrogel, a polymer network that naturally retains a lot of water. Atmospheric water harvesting draws water from humidity in the air.
