Degrowth or Extinction

The North Ayrshire battery recycling plant, very respectful of the environment and one of the "key" for fighting global warming, has just exploded.

The amount of released toxins is equivalent to that of 1,000 trucks with poorly tight diesel engines that circulated without stopping for more than 10 years, according to reports.

"Why the Biggest Battery Company is Betting Against Lithium" [14:32 min]

Why the Biggest Battery Company is Betting Against Lithium. Sodium-ion battery technology isn’t exactly new, but something interesting is happening. CATL, the world’s biggest lithium battery manufacturer, says that up to half the market could switch to sodium. That’s right—the biggest name in lithium batteries is betting against lithium. Looks like lithium might need to recharge its reputation. After all, sodium-ion batteries are nearly as good lithium, and salt is much cheaper and easier to access than lithium. So maybe its not surprising that CATL and some other companies are getting ready to manufacture huge numbers of them in preparation for what could be a massive market shift. But is sodium really the future of energy storage, or is it just another battery technology destined to live in lithium-ion's shadow?"

🔋Improving Aluminium-Ion Batteries with Aluminium-Fluoride Salt.

There are many rechargeable battery chemistries, each with their own advantages and disadvantages. Currently lithium-ion and similar [e.g. Li-Po] rule the roost due to their high energy density at least acceptable number of recharge cycles, but aluminium-ion [Al-ion] may become a more viable competitor.

A published paper by Chinese researchers claims to have overcome some of the biggest hurdles. In the paper as published in ACS Central Science by [Ke Guo] et al. the use of solid-state electrolyte, a charge cycle endurance beating LiFePO4 (LFP) and excellent recyclability are claimed. <https://pubs.acs.org/doi/10.1021/acscentsci.4c01615> It’s been known for a while that theoretically Al-ion batteries can be superior to Li-ion in terms of energy density, but the difficulty lies in the electrolyte, including its interface with the electrodes. <https://en.wikipedia.org/wiki/Aluminium-ion_battery>
[ImageSource: ACS Central Science] The newly developed electrolyte (F-SSAF) uses aluminium-fluoride (AlF3) to provide a reliable interface between the aluminium and carbon electrodes, with the prototype cell demonstrating 10,000 cycles with very little cell degradation. Here the AlF3 provides the framework for the EMIC-AlCl3 electrolyte. FEC (fluoroethylene carbonate) is introduced to resolve electrolyte-electrode interface issues. A recovery of >80% of the AlF3 during a recycling phase is also claimed, which for a prototype seems to be a good start. Of course, as the authors note in their conclusion, other frameworks than AlF3 are still to be investigated, but this study brings Al-ion batteries a little bit closer to that ever-elusive step of commercialization and dislodging Li-ion.

A very quick #SolarUpdate for the first week of April.

We've had 7 days of lovely sunny weather, very unusual for this time of year, and another 5 days of it predicted until the weekend.

How does that affect the running of the house?

So far, we've spent
£6.49 on electric inc standing charges
£7.06 on gas inc standing charges

We've earned

£9.12 from exporting electric

Which gives us a balance of £4.43

The standing charges alone for that week are £6.65

So we've covered all of our gas & electric use and a third of the standing charges so far.

The weather won't last... But it's reminder that a little bit of sunshine can do wonders, not only for your mental health and well being, but for reducing your reliance on energy. We've been using the conservatory (it has a laminate roof) as a heater for the house. It gets so hot in there, even in colder weather, that you can open the doors and let that warmth into the house, avoiding the need to have the heating on at all during the day.
