Scientist & Group Leader for batteries & electrocatalysis (🔋/🧪/⚡) // #batteries, clean energy & other stuff 🌎
It's Holocaust Memorial Day and Musk & his American 🇺🇸 oligarchy bros think they need to teach us Germans that the right-extremist AFD is the only party that will "save Germany" right before the election & that we should be proud of 🇩🇪 history, let go of the "remembrance cult"

This makes me sick!

Interested in thermal #energystorage? 🔥
My colleague Marc Linder - group leader at DLR in that field - is an incredibly good #science communicator

You can listen to one of his public lectures here:

I could listen to DOMINIK EULBERG talking about the wonders of #nature 🌍 for hours & I just discovered he has a new podcast where he does exactly that wunderkammerpodcast.de (in German) ❤

... he's also my favorite techno DJ & an inspiration for fusing #science (he's a biologist) & art

According to today's hearing in 🇩🇪 parliament, the ministry of research & education decided to stop funding battery research 🔋 because

⏹️ the "open technology development" ideology forbids prioritizing technologies over others
⏹️ no fundamental research necessary anymore on batteries
Anhörung im Bundestag zur Zukunft der 🔋-Forschung in 🇩🇪 macht nochmal deutlich, wer für die Kürzungen im BMBF verantwortlich ist (für wen es nicht ohnehin schon klar war..) 👇🏻

When TIME selected me for the Time 100 Climate list this year, they asked me: What is the single most important action you think the public, or a specific company or government (other than your own), needs to take in the next year to advance the climate agenda?
Here was my reply... 🧵

I need some positive news! 🙏🏻 Please tell me that some of these are still happening (and moving forward) #battchat

Am selben Tag Frau Ministerin a.D. mit folgender Aussage 👇🏻 wie nennt man solch ein Phänomen noch gleich?

Ok then. Let's give it one more try, I guess 🤷🏻

Wunder #Batterie? 🔋 Wichtiger:
Es läuft "nicht darauf hinaus, dass eine Zellchemie die beste ist & andere verdrängen wird. Vielmehr werden je nach Preissegment unterschiedl. Zusammensetzungen mit ihren jeweiligen Vor- und Nachteilen zum Einsatz kommen" 👍

And on more: Great news! After NMC-based lithium-ion & lithium metal (Cuberg), Northvolt 🇪🇺 adds sodium-ion to its portfolio (collaboration with Altris, prussian-white cathode). Technology delivers best-in-class 160Wh/kg but unfortunately no info on timeline.

Here we go! First large-scale manufacturing of sodium-ion battery 🔋 cells announced by Chinese 🚗⚡leader BYD

Goal is an output of 30GWh/a, enough for 1-2 Mio electric "microcars" (15-30 kWh battery). Unfortunately no timeline, but I guess 2024/2025

cnevpost.com/2023/11/20/b...
BYD signs deal with local conglomerate to build sodium battery base with 30 GWh annual capacity
The sodium battery base is planned to have a total investment of RMB 10 billion and an annual capacity of 30 GWh.

So, where are the battery people on here? What do we call ourselves? BatterySky?

Nice graph from the new Intercalation Station newsletter showing the various #battery 🔋 companies claiming ultra-fast charging below 10min

Very different approaches - from material-level (silicon-, niobium-based anodes) to electrode (3D-structured) and cell design (pre-heating)
