12 2014Electrochemical energy storage devices consist of electrode materials, electrolyte, and current collector, which is critical to the overall electrochemical performance. There is an urgent need to solve the safety problems of lithium ion battery (LIB) for application in electric vehicles and power storage. The commercial separators suffer from poor dimensional thermo-stability, flammability and poor wettability. Professor CUI Guanglei and his group from QIBEBT has carried out the interface study on key materials to improve the electochemical energy storage capacity.

polyurethane hydrogels with strong mechanical strength and high water-absorption ratio may find their applications in soil-water conservation and desertification combating. By carefully tuning the structure of polyols and the density of the cross-linkable functional groups, professor WAN Xiaobo and his colleagues found a way to unify the high water-absorption ratio and high compressive strength in one material.
Polyurethanes that could form hydrogel when contacted with water are of great interests for their plausible applications. It could be used as high-performance industrial materials and materials for medical treatment.
Figure 1. Polyurethan...
