    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.

      That doesn’t answer the question though, does it? I’ve been using a silicon carbon battery phone for over a year now and it’s the best battery experience I have ever had with any phone, by far. And it’s a foldable!

      Charging is also the fastest I’ve ever experienced in a phone. 5000mAh and 60W PD charging.

      I will never buy a lithium battery phone again, ever. So if Samsung wants me back as a customer, they will have to switch. And I don’t understand why American and Korean phone manufacturers are taking so long with this.

        Well then if I must answer the question to satisfy you, the answer is it’s too difficult and expensive to manufacture them right now

        You may have a great battery, I’m proud of you for making that consumer purchase

        But the technology is still in its infancy

          Ok but why is it too difficult for American manufacturers and not for Chinese ones?

            Man will you just shut up and leave me alone

            Your first reply to me was dumb, because I already answered it… You just didn’t bother to read it

            I really don’t care about your feelings because you bought this battery and you need validation

            Just stop and leave me alone

            Stop badgering me with pointless leading questions. You phrase them in such a way that they are rhetorical, yet you probably want an answer, WHICH YOU WILL ALLOW TO SAIL OVER YOUR HEAD, YOU’LL COMPLETELY IGNORE, AND THEN YOU’LL PROCEED WITH ANOTHER POINTLESS QUESTION

            If you can’t ADD something to this conversation, leave. I’m not interested in this little performance you’re putting on here, it’s completely intellectually dishonest.
