As you said, “it is rapidly developing.” That doesn’t make what I said wrong, as there has been a large delay between the development of power generation technology and power storage technology. Thanks for emphasizing my point

Semantics. They're two separate animals. There are times solar improvements outpace storage and times battery outpaces solar (solar's winning, but only because it was so bad). A lot of headway recently with replacing indium in cathodes. But perovskites are also gaining ground. We need all the tools.

Cool. So why are you arguing semantics with me if we basically agree?

Because arguing over syntax would be silly? Or maybe because it's not black and white. One of those, certainly

LFP is the first quantum leap in regards to safety. Saline batteries will be the next step.

Fascinating! You’ve given me some reading to do 😊
