    I’ve been reading about battery breakthroughs for decades. And I remember when the latest in battery tech was alkaline, then Ni-Cd, then Li-Ion, and now LiPo. All of those have ended up in consumer products.

      Also, the battery pack for a cell phone 30 years ago was about the same volume and weight of an entire smartphone, with a capacity of about 500 mAh. They are also far cheaper if you account for inflation.

      Batteries have improved incapacity by about a factor of 10 and the cost per watt-hour has reduced by about 99% in the last 30 year. All without a single advancement in the technology, apparently.

        I wouldn’t call it a single advancement but hundreds. The materials might be largely the same but manufacturing is huge. When you roll up some metal to make a battery then increasing the number of layers is a huge challange when they’re already tiny.

        What do you mean by that?

        I would say there have been a great many advancements in technology. I mean, that’s what all these improvements are, right?

          It was sarcasm, which seems to be harder to convey in text than any number of battery advancements.

      You skipped Ni-MH there, that was major for not having the memory problems of Ni-Cd. We still use those in AA and AAA rechargeable batteries.

      A little pedantic note, LiPo is still a type of Li-Ion (maybe I got that right)

      and the bigger recent breakthrough was LFP (Lithium iron phosphate / LiFePO4)

      And probably safe to call Sodium-Ion and solid state the next big phases of development

        LFP is actually a relatively old battery technology, it’s only now that the patent is expired that it’s starting to breakthrough (outside of China, they somehow got a license if I understand it correctly).
