You're not missing something. Lithium is cheaper on the long run if you want a lot of cycles.
That's good to know, I'm trying to learn about battery technology and cutting my way trough all the marketing stuff..
But you mentionned Li-ion, this ain't li-ion, it's lifepo4. Li-ion probably doesn't have much cycles.
You're right, it is hard to get rid of old bad habits... I read lifepo4 as 'Life-Pee-Oh-four', which sounds like marketing speak, instead of the proper LiFePO
4 (lithium ferrophosphate). While it is still a lithium-ion battery (according to Wikipedia) it is no longer the Li-ion of old...
On another subject, that Siemens HVDC stuff you linked earlier already answered a few questions I had yet to ask, as a new 1000KW HVDC line is being built just a few kilometers from where I live...
Thanks again!
