Prof. Fichtner & Dr. Bresser - Sodium-Ion Batteries

May 7th, 2023 Sodium-ion batteries have been overshadowed by lithium-ion batteries for decades, but there is a thousand times more sodium in the earth's crust than lithium. And now battery chemistry has evolved to the point where sodium-ion b... Learn more

Prof. Fichtner - CATL "Condensed Battery"

April 26th, 2023 Have the European battery producers completely lost touch? Chinese battery manufacturers are celebrating new product successes everywhere: The first sodium batteries (BYD, CATL, 2021) are being produced in Asia, high-performa... Learn more

Prof. Stein - Pulsed charging in battery formation process

April 23rd, 2023 Traditionally, fresh battery cells are carefully charged for up to 24 hours immediately after production. This "formation process" is cost-intensive, time-consuming and usually takes a long time. A group of battery researcher... Learn more

Self-healing Batteries - Prof. Binder & Dr. Marinow

April 16th, 2023 Wolfgang Binder & Anja Marinow from the Martin Luther University Halle-Wittenberg are developing self-healing battery materials using nanostructured polymer materials. These are composites that consist of repeating units (mon... Learn more

Supercapacitors - Dr. Pohlmann & Dr. Fleischmann

April 12th, 2023 This podcast is dedicated to an energy storage device that is often underestimated in materials science: the ultracapacitor. This is installed, for example, for regenerative braking in vehicles such as buses, trains, cranes a... Learn more

Prof. Dr. Bruno Burger - Reforming the electricity market

April 2nd, 2023 How are electricity prices determined? Is the merit order model, which forms the price on the electricity exchange, still up-to-date in relation to the increased conversion to renewable energies? Our expert in the loaded podca... Learn more

Self-healing batteries - Prof. Maitane Berecibar

April 2nd, 2023 Self-healing materials have the ability to automatically repair damages to themselves without any external diagnosis or intervention. Soon, they could be used in battery electrodes as well! This would impact the entire battery... Learn more

Prof. Stefan Krauter - Low electricity bills due to nuclear power?

March 26th, 2023 The days of German nuclear power are numbered. The last three nuclear power plants are scheduled to go offline in mid-April 2023. The German nuclear phase-out, which was first initiated under the red-green federal government ... Learn more

Prof. Birgit Esser - Inexpensive flow battery for wind & sun

March 19th, 2023 The company CMBlu praises its organic flow batteries as environmentally friendly stationary storage for renewable energies, which should also be inexpensive and easily scalable. The organic flow technology is intended to comb... Learn more
