Density doesn't really matter for stationary grid storage, where even slightly lower battery costs can easily outmatch higher space requirements.

- zardo 2y agoIt matters, but only as much as shipping costs matter.
- rockskon 2y agoGiven the stated use cases of the post I responded to was electric vehicles and mobile devices, my response was framed in terms of that. Consumer devices - especially phones - famously prioritize battery life.
- shkkmo 2y agoThey also prioritize price, especially at the low end. If sodium batteries are significantly cheaper, it will be used to produce low cost devices.
- rockskon 2y agoWhat? Smart phones are famously high-margin devices. What do you mean "prioritize price"? Not for most smart phones.
- IntelMiner 2y agoThere's a few billion people who can't afford the latest model iPhone or Google Pixel device each year
- rockskon 2y agoAnd that's a pretty big caveat! Helpful framing to highlight who'd be most likely to benefit from this.
- ekianjo 2y agothere are a lot of smartphones sold for low end markets like India and China. most of the worlds phones, actually. not everyone lives in California and makes a million a year
- spurgu 2y agoEven though I could easily afford an iPhone or Pixel my daily driver is a $150 Android phone. Due to the low margins of the manufacturer it's actually a very usable device.
- kube-system 2y agoThere are already batteries cheaper than lithium ion batteries, but they are not in low-end phones, because a low-end lithium ion phone battery is still only a few dollars.
