Re: Sila Nano battery launch - Big Whoop Well, the Sila nano battery is kind of launched - but in a smartwatch application from a company (Whoop) that I'd never heard of before reading about it in the article about the Sila Nano. The Sila battery pack for the Whoop is probably around 1/2" X 1/2" X 1/4" in size, for a total volume of 0.0625 cubic inches. This compares with a volume of about 11,300 cubic inches for a Tesla model 3 battery pack. So 11,300/0.0625 = 180,800 of the Sila Nano battery packs in the Whoop 4.0 smartwatch could fit in the same volume required for one Tesla model 3 battery pack. I'd never heard of Whoop before, but let's be generous and assume that they'll sell 10 million Whoop 4.0 smartwatches per year, meaning that Sila will have to produce 10 million battery packs per year. If we assume that the energy stored in the Sila Nano battery pack and the model 3 battery pack are proportional to their sizes (probably approximately true), the total annual production of the Sila Nano battery will be equivalent to 10 million/180,800 = about 55 Tesla model 3 battery packs, even with the optimistic assumption that Whoop will sell 10 million of their smartwatches per year. So, the Sila Nano battery is not really what I would call in production - more like pilot production. Still, it's an important first step - we'll have to see how the battery does in its first real-world application, and whether it can be manufactured profitably and reliably in larger numbers and physical sizes. |
