@leveragegrinding as always I am missing the sources@ccf

@Koenigmidas True. Your objection is justified. On the one hand, my school time is only a little less than a year ago, where one actually treats the whole chemical syntheses to renewable energies very intensively. In fact, I have to deal with the whole subject area around process technology, energy conversions, energy carriers and energy markets every day about 10h, be it via audits, "meetings" or "further education", and am therefore quite strong in the material. The contribution to my profession I put however in the meantime "privately". If I take sources, I note these usually beside it. The rest is personal speculation, so no more detail on battery manufacturing and automotive manufacturing, as I have very little and only rough knowledge of it. 😅

@Hannes_SK OK for your honest answer you get it from me too. What is your opinion about the process of standard lithium and how good is the use of lithium iron phosphate?

•@Koenigmidas First of all, thank you! I continue to see the reason on getquin that everyone here knows something and we can all help each other. 😁 Standard uses DLE. This refers to the lithium chloride example above, which is what you need to extract from a source. That is, the salt is dissolved in water. Similar to sea salt extraction. To do this, you have to evaporate the water content. In the long run, however, this leads to the drying of the lake. Now, however, you can also let this brine flow via adsorbents. Lithium accumulates on this agent, the rest continues to flow and can be added to the lake again. So it's comparatively environmentally friendly. On the other hand, such adsorbents are very expensive to purchase compared to acid treatment. In addition, you need further chemicals to recover the lithium from them. So to regenerate or desorb these resins. So now you have a lithium mixture again, which you have to process in such a way that you can make it usable again ... So it's very costly, but also very environmentally friendly. But I think that even if the price of lithium hydroxide is halved, it should still be very profitable. And regarding Li iron phosphate: This is more in the direction of e-technology and therefore direct competition for my work. As long as you store your home electricity, it is supposed to be the successor of the usual lithium-cobalt battery. But is probably mainly safer, because of the temperature resistance of the phosphate part. Definitely more durable, but capacitively "inferior". But research continues there as well. I mean, BYD has taken on the topic in the long term. But as I said, battery technology is really not my field. I'd have to look into that in more detail, though. 😅
