OnePlus Rumored To Be Working On A Future Snapdragon 8 Elite Flagship With A Humongous 7,800mAh Battery, Likely Using Silicon-Carbon Technology To Push The Capacity Limits

It's been known for years that silicon is much better at storing lithium ions, like insanely more efficient than graphite which is what's currently used in anodes. But it's ability to pack in the lithium ions is its downfall... Charging and discharging embrittles it by actually and expanding/shrinking the lattice

So it took a few years to surmount that challenge. Figuring out how to not have the material destroy itself, and finding the balance of how much energy to store. As far as I know there's a few different approaches that involve deposition of individual molecules into crystals.. and nanotech photo lithography and crazy shit that's honestly too hard for me to keep up with.

There's all kinds of hype surrounding them and people talk about them being like an order of magnitude more efficient than current LiPo technology, but that's a lot of hot air, we're looking at like 30% improvements now with slightly increased charging times... huge complexity increases in manufacturing... cost... We don't even know what's going to happen when we deploy a couple hundred million of these.

They're going to be the next big thing for batteries but we're kind of in the early adopting phase right now.
