Some spyshots have been caught of Tesla's new battery.
 https://electrek.co/2020/09/16/tesla-battery-cell-in-house-roadrunner-first-look/ Tesla's "Roadrunner" tabless battery cell that's supposed to last 1 million miles, have greater energy density, and lower waste heat. Expected to be used in Roadster, Cybertruck, and Plaid Model-S. Aiming for <$75/kwh cost. |

If it comes in a deep cycle and/or starting/cranking format, I'd be interested. Looking for new batteries for my boat.

So 40mm or so by 80mm?
More than double the diameter of an 21700 by the looks of it so a lot more volume. |

Every "revolutionary" battery advancement in my lifetime has been meh. They've been promising "breakthroughs" that will enable electric vehicles to not be a joke for everyday use since I was first old enough to drive.
I'll get excited when REAL products hit the shelves for consumer use that are significantly better than current lithium batteries. |

Right now the tesla powerwall is 13.5Kwh and cost about 1k per kwh. 100ah 12v lipos for solar systems start at about $750. So $75 is a big deal.

Considering home solar lithium storage is about $750 per kwh... This is a 10 fold decrease in price. It will be fucking HUGE for everything.
Home solar panels are closing in on 500wh per panel (at $0.50 wh now too.) |

I think the 500 cycles number is based on maximum continuous discharge until they're dead. So the battery is working the hardest it can and running it down past where you would in most applications. I have 18650 cells that have thousands of cycles |

Home solar panels are closing in on 500wh per panel (at $0.50 wh now too.) What I'm seeing (I've owned an electric car and a couple hybrids) is that the cost per kWh is production cost, not end-consumer cost. So you and I won't be able to go to ye olde battery store and buy a 1kWh battery pack for $75. It'll probably still cost us hundreds. In 2017, I bought a camper and really would have loved to have a lithium battery for it. $1k for a 100aH 12V equivalent. In 2020? $1k. Prices on consumer units haven't gone down much at all. If car manufacturers can start baking in (or baking out) that reduction in cost to the sticker price, then we'll see movement. |

I have 18650 cells that have thousands of cycles Yes those are complete charge/discharge cycles, everyone who’s honest goes by complete cycles, because anything else is arbitrary, and easier to defraud, (if you discharge you cells less than your competitors, your battery will out perform them) And yes if you baby a cell and don’t deplete it entirely every time it will last much longer, if tesla isn’t bsing us, then a babied battery could go for a LONG time. there are Tesla’s with original batteries in them with over 600,000 miles on them now, but as you said, they’ve been babied to some degree. Most tend to last between 300,000 to 500,000 miles depending upon use/abuse, it should be noted that the upper number on that average is still rising. |

I always like new things. I have been holding off on a battery pack for a while now. $1000 vs $7500 would Be an enormous game changer not just for off the grid living but also for maintenance of the power grid itself. Think about all the homes charging the batteries at night where there is less Voltaic draw and then discharging during the day to power the air conditioning lights and computers that are otherwise dormant at night.

Missed it a little 100wh battery would be $7.50 A golf cart battery, fairly inexpensive lead deep cycle, is ~$100 per kWh of storage So they are trying to make something cheaper per kWh, which is presumably much, much lighter, smaller and has a much higher charge and discharge rate It’s a very big deal if they can do it I suspect the technology is still a number of years away |
