A PEO-based gel polymer electrolyte for lithium ion batteries

A lithium-ion conducting gel polymer electrolyte (GPE) membrane containing PEO as a polymer host and liquid electrolyte has been prepared by a simple one-step procedure. The prepared electrolyte membrane exhibits a good ionic conductivity of 3.3 10 3 S cm 1 and high lithium transference number of 0.76 at room temperature. Meanwhile, the gel polymer electrolyte membrane shows very good thermal s...

Advanced gel polymer electrolyte for lithium-ion polymer batteries

In order to keep abreast with the rapid development of portable electronic equipment, improving the performance of polymer electrolytes has therefore become our goal of research. This work improved performance of Li-ion polymer batteries through advanced gel polymer electrolytes (GPEs). Comparing with liquid type Electrolyte, Gel type Polymer Electrolyte (GPE) had the advantage of a wide variet...

A superconcentrated ether electrolyte for fast-charging Li-ion batteries.

We have found ultrafast Li(+) intercalation into graphite in a superconcentrated ether electrolyte, even exceeding that in a currently used commercial electrolyte. This discovery is an important breakthrough toward fast-charging Li-ion batteries far beyond present technologies.

Basic chromatographic properties of polyethylene glycol-type, polymer-based monolithic columns.

We have prepared polyethylene glycol (PEG)-type, polymer-based monolithic columns (PEG-type columns) to study the basic properties of PEG-type monolithic polymers. Chromatographic characteristics of the PEG-type columns were obtained using a semi-micro HPLC system while polycyclic aromatic hydrocarbons and benzene derivatives having various functional groups were utilized as solutes. Results we...
