    The new material provides an energy density—the amount that can be squeezed into a given space—of 1,000 watt-hours per liter, which is about 100 times greater than TDK’s current battery in mass production. Since TDK introduced it in 2020, competitors have moved forward, developing small solid-state batteries that offer 50 Wh/l, while rechargeable coin batteries using traditional liquid electrolytes offer about 400 Wh/l,

    Am I missing something?
    • The new method offers 1,000 Wh/l.
    • It's 100x more than previous.
    • It was introduced in 2020 (so not a recent breakthrough, or the 'current' tech was introduced in 2020).
    • Competitors offer 50 Wh/l (so not 100x as much).
    • Traditional electrolyte batteries offer 400 Wh/l.

    None of this makes sense to me. If traditional means offer 400 Wh/l, this is only 2.5x as much. If TDK's current tech offers 50 Wh/l, this is only 20x as much, not 100. If the tech was introduced in 202, it's not new. If it offers only 50 Wh/l, it's not a breakthrough.
