Let's hear it for Nick and Darren, two CoC graduates from the class of 2015 in ChemE who are passionate about early education. They recently co-authored a children's book about batteries called "My Baby's First Climate Book: Batteries!" #alums #gobears #climatescience

@shagun_mm @CarnegieMellon @Tesla Congrats!!

[Nicholas Yiu @nicholasyiu]

“My Baby’s First Climate Book: Batteries” is out now!

co-authored with Darren Lim, perfect for sparking tiny STEM brains. Got kiddos? Grab a copy and start them young 📚⚡👶

Happy national battery day from @naatbatt! 🔋🔋🔋

[Nicholas Yiu @nicholasyiu]

@drpatrick I've got ideas for batteries. Let's chat. DM me.

Following on from Redflow bankruptcy and now widespread breakdown / failure of the existing now unsupported projects

Something that’s not well understood is batteries need to be internet connected for monitoring and diagnosis, most systems talk back to mothership for software updates and for ongoing diagnostics/ cell balancing / maintenance (another security risk)

When the company that supplies the battery goes bust you loose the maintenance / diagnostics of that unit and usually within months you end up with a very expensive brick

There’s no longer support on the backend for Redflow that’s been turned off with their bankruptcy. A maintenance specialist could keep these going but likelihood is they really need replacing, plus other ongoing projects need picking up by an alternative supplier

400kWh was due to be installed to USNAS Sigonella in Sicily in Aug ‘24 (afaik not done)

More importantly it’s part of DoD extend storage program covering 450 bases!! Wonder who fits that requirement…

saw raccoons last night for the first time in my life. very cute!!!

@tfeldmann Great stuff @tfeldmann !!

[Nicholas Yiu @nicholasyiu]

@ShanuMathew93 @JacobLBrown Good points both. Based on other cases, it can take 5+ years to start making cells consistently and profitably. Stuff goes wrong , then it takes a long time to find out the source of the problem. And a battery factory is really like 10-20 factories combined and merged into one.

[Daniel Rau @drauwsy]

Long thread on why I do not believe any western LIB recycler will be able to succeed.

TLDR;
- Feedstock availability is scarce and cathode chemistry is ever changing
- pCAM and CAM specs is ever changing
- Recycling processes are inherently inflexible
- Lack of human capital & know-how in the west
- Environmental issues are insurmountable
- 2021/2022 got everyone overzealous on contracts, feasibility

[Nicholas Yiu @nicholasyiu]

The Western world does not comprehend how truly difficult (and unique) battery making is at scale. A sad day for @northvolt.

[Ed Conway @EdConwaySky]

Yesterday Northvolt, the great hope of European battery manufacturing, filed for bankruptcy.
Today the CEO resigned.
Yet more evidence that
a) making batteries is hard
b) competing with China is hard and
c) Europe has a real challenge in the coming years https://t.co/ozyRE5ZeN4
