On my way to Gothenburg for today's Batteries Sweden meeting, and the train is currently at a standstill outside of the final station because we are 20 minutes *too early*. This is first, at least for me...
Possibly the most embarrassing thing I've ever seen. Unbelievable
Battery charging window in iOS on iPhone 16, showing the ability to set a custom charge limit
iOS does have this appreciated feature now, for newer devices at least.
Live from PyBaMM conference. Delighted to see my name in one of the best and funny slide I have ever seen at conferences #battchat
I actually bought a (very cheap) soldering iron today just for this, haha. Ironically I probably last owned one about the time I should have fixed this the first time. There's a little bit of technique to it but once you get it down it's not hard to do a functional job!
Nice! My efforts weren't so comprehensive this time, but now that I went to this effort I'm trying to resist the urge to completely change the configuration of one or two of my others :p
2004 Ibanez RG1570
It is a 2004 Ibanez RG1570, slightly modified :)
A freshly (and correctly) rewired 5-way pickup selector switch installed in an Ibanez RG electric guitar.
In today's "better late than never" news, I have at last gotten around to rewiring the pickup selector switch on one of my guitars, since I had a tech install new pickups in it a while back and they did the switch backwards. That was about 18 years ago
A row of homemade classic English iced buns, just begging to be eaten
A homemade slice of nostalgia while the family is stuck at home with the winter vomiting bug. Let's see how good a cure they are. Not sure if I've even eaten one since the 90s...
The fallout from Northvolt's troubles continues now at Novo Energy (Northvolt-Volvo JV), who have announced plans to reduce headcount 30%. Very unfortunate and hoping for the best for friends and former colleagues at Novo. #battchat
More woes and worry for the Nordic battery startup world, Morrow will cut ~25% of staff as production delays are forcing them to cut costs #battchat

Really looking forward to this album. The new single took me back to listening to the 9.11 album for the first time 23 years ago, all over again. Can't wait to hear it, and can't wait to completely fail at learning to play the songs!
Same here. As one of the last big websites which isn't shit, I figure Wikipedia is worth the support.
Really interesting work. Shall make a point to read both in more detail!
Last day in the lab before holidays, had to hack the glove box touchscreen to work with a mouse since it stopped responding to touch, now trying to resist the urge to try and install DOOM on it
I fully endorse this, as I'm sure you guessed :)
The description of Wh/kg on single electrode/material level for example bothers me no end. Since it is always calculated using a potential, which of course is vs a reference, it should be Wh/kg vs something
My second 🔓editorial for @naturenano.bsky.social is out. This time, I talk about something I care a lot: Why do battery researchers not use a shared basic electrochemistry terminology?

What's your experience? 🙂

A can of "Lusse Lelle", a Swedish sour beer with a strong taste of saffron
Dear Sweden: I know you like saffron, especially at Christmas, but in this case... no, I don't think so
In your line of work I assume you've seen it all!
If Bluesky is to replace X for news, global coverage is key.
There are consequential events happening in Syria, Ukraine, Georgia, Sudan & Gaza right now.
This pack includes reporters on the ground there & analysts.
Pls consider following these to share their reporting & build Bluesky's news value
I had a brief scroll on 'X' for old times' sake recently. Top of the lists were Trump and Musk tweets, followed by some conspiracy theories, a couple of flat earther videos, crypto, AI generated slop, some Hitler worship, maybe 1 post in 100 worth reading. Let it rot
Steam train on the Eastern Södermanlands Railway arriving in Mariefred
Santa Claus, having arrived in Mariefred on the train, is transported on pony-drawn cart to the town square
Santa visits Mariefred in style for the Christmas market, taking the museum railway into town followed by a pony-drawn cart to the town square (with a huge crowd of families close behind)
I've seen something similar before. Also possible to short cans over longer distance with many series connected cells between. Then you get a higher voltage spark with lots of power, enough to locally heat materials to very high temp and start thermal runaway, even if shorting terminals does nothing
Assuming I'm reading it right, it checks out - if two cell cans in series stack come into contact and they're not isolated then one cell will short. A number of ways to minimise that though now. Didn't they use to market these as not able to catch fire?
I'm curious about the cycle life too. All the real data I've ever seen (likely outdated now) doesn't indicate great cycle life (and much worse calendar life) but spec sheets suggest almost on par with LFP. Interested to know if there is real data or just unverifiable numbers
Great to see you here David!
It's probably true but it's outdated and the ramp has progressed. ~3 GWh is my translation of their previous goal of 100k cells/year which I realise now they admit they won't reach. But they did 60k in a week two months ago, which would be a bit under 2 GWh annualised by my reckoning
Yes, scrap rate has been publicly reported as one of the biggest problems
They do have functional production. Their publicly communicated end of year target should amount to something like 3 GWh/yr. It's not where it should be, but it's not nothing
First Christmas market of the season (Taxinge slott)
