Feststoff Polymerelektrolyt-Membran - Verfahren zur Herstellung einer Polymer-basierten ionenleitenden Feststoffelektrolytmembran für Lithium-Batterie

05.05.2015

Bei der vorliegenden Erfindung handelt es sich um ein Verfahren zur Herstellung dünner Polymer-Elektrolyte, die zudem mechanisch stabil und gleichzeitig auch flexibel sind. Diese zeichnen sich durch gute ionische Transporteigenschaften aus, d.h. die Leitfähigkeit bei Raumtemperatur beträgt 1 mS/cm. Die Membranen können aufgrund ihrer mechanischen Eigenschaften in Lithium-basierten Energiespeichen gleichzeitig als Elektrolyt und Separator eingesetzt werden. Das Verfahren ermöglicht die Verarbeitung von Polyacrylnitril basierten Membranen zusammen mit dem Lithiumleitsalz und ermöglicht eine gleichmäßige Materialstärke.

Im Focus: A Chip with Blood Vessels

Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.

Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...

Im Focus: A Leap Into Quantum Technology

Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.

In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...

Im Focus: Research icebreaker Polarstern begins the Antarctic season

What does it look like below the ice shelf of the calved massive iceberg A68?

On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.

Im Focus: Penn engineers develop ultrathin, ultralight 'nanocardboard'

When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure

Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...

Im Focus: Coping with errors in the quantum age

Physicists at ETH Zurich demonstrate how errors that occur during the manipulation of quantum system can be monitored and corrected on the fly

The field of quantum computation has seen tremendous progress in recent years. Bit by bit, quantum devices start to challenge conventional computers, at least...
