In our Sunday newsletter, we editors reflect on the past seven days. We do this on the initiative of our cartoonist Albert Jan Rasker. He chooses a subject, draws a picture, and we take it from there.

While you are probably just finishing your umpteenth egg, we break in very briefly with our weekly news summary. Just so you get some mental inspiration too… 👨‍🎓

We have said it a hundred times, and we will continue to say it: in the puzzle of our new energy system, balancing supply and demand for energy is the biggest challenge. Batteries are part of the solution. At IO, we pay attention to them almost daily.

Unfortunately, batteries do not last a lifetime. So as their numbers increase, so do concerns about disposing of discarded ones. Not only because of the limited availability of raw materials but especially because battery waste deserves another chance, initiatives have sprung up around the world to encourage reuse.

The passport

Albert Jan’s eye caught one such initiative: the battery passport that will be mandatory in the European Union in three years. From February 2027, every new EV and industrial battery in the EU must have this digital identity. It is a step to ensure that batteries perform well, are recyclable, and are environmentally friendly. This digital profile contains essential data such as the battery’s unique serial number, production date, type, chemical composition, manufacturer data, and performance data. The QR code ensures that all this information is easily accessible.

As mentioned, we keep our readers informed about the world of energy storage. Like recently in our magazine, which was completely dedicated to it. It can be read digitally here:

‘IO Next: Energy Storage’

And while we’re on the subject of batteries… be sure to check out Mauro Mereu’s series EVolution on the development of electric vehicles. Here are the first three episodes.
