#2He projects (at current growth and experience rates) that battery cells will reach $8/kWh by 2030. Wow!

#3What level of subsidy do we give to batteries?

#4The cost of 50AH Li-Ion batteries is getting close to the point where they may start to compete with Lead acid for gas powered cars.

#5Current prices are kinda nutty and are largely determined by the size of your buy. Retail prices for home batteries (a few kWhs) are roughly $1000/kWh. A Model 3 gets you about $700/kWh (with two free motors and an ipad). A Tesla megapack is $290/kWh, but you have to spend $1000000 to get that price. Tesla probably gets cells from the factory at round $80-$90/kWh.
Long-term it seems pretty reasonable that retail prices should be a small multiple of the factory price (which keeps decreasing), so I think $1000 for a 20kWh battery is totally reasonable.

The environment be damned: Regarding price / energy density, yes. They even have weight / energy density advantage.
But Lithium batteries can't be recycled. Saying "We are almost there" and "The future looks bright about it" is "moving fast and breaking things" again

At $1k for 20kw/h, I'd be very tempted to massively over-panel the roof and front/back yard on pergolas, install 200kwh of battery and never deal with pg&e again

Where I live there is a warehouse where you can withdraw new MANYI Lifepo4 cells at around 97€/kwh (a single cell) after contacting the seller on Alibaba, so I'm guessing Telsa is getting them at 80 or even less.

They can be recycled, its just currently more expensive than the post-product

I thought they could be recycled but at the moment it’s cheaper to mine. Is that not true?
