High Performance Solid Polymer Electrolytes for Rechargeable Batteries: A Self‐Catalyzed Strategy toward Facile Synthesis

It is urgent to seek high performance solid polymer electrolytes (SPEs) via a facile chemistry and simple process. The lithium salts are composed of complex anions that are stabilized by a Lewis acid agent. This Lewis acid can initiate the ring opening polymerization. Herein, a self-catalyzed strategy toward facile synthesis of crosslinked poly(ethylene glycol) diglycidyl ether-based solid poly...

A PtRu catalyzed rechargeable oxygen electrode for Li-O2 batteries: performance improvement through Li2O2 morphology control.

Albeit ultrahigh in energy density, the Li-O2 battery technology still suffers from the high overpotential of Li2O2 oxidation upon charging and the low cyclability. In the present work, we use Pt2Ru/C as the oxygen-electrode catalyst and study how it improves the cell performance and changes the reaction mechanism, as compared with a carbon electrode. Multiple methods, including X-ray diffracti...

Process Improvement Based on External Knowledge Context

The external environment of an organization is characterized by significant changes that occur in the social, economical, political and technological fields. The organization should know this setting and act effectively. A major challenge is how to define significant information in its diverse contexts. In a business process scenario, context could be defined as the minimum set of variables con...
