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...

Li ion transport in an intercalated polymer electrolyte

Lithium ions solvated by polyethylene-oxide ~PEO! have been confined by intercalation within the galleries of an insulating, inorganic layered solid CdPS3 . The dc conductivity of this confined polymer electrolyte Cd0.75PS3Li0.5(PEO) displays a distinct change in the mechanism of conduction with temperature, exhibiting a crossover from an Arrhenius temperature dependence at low temperatures to ...

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...
