    For starters, lifespan is dramatically improved. The Revv1 EVO’s battery is rated for over 1,200 charge cycles before dropping to 80% capacity. That’s more than double what you’d expect from a typical e-bike battery, which often lasts around 500 cycles

    Let me introduce you to my friend LFP. 5k-10k cycles, easily.

    The battery can fully recharge in around two hours, thanks to its chemistry AND Ride1Up’s inclusion of a high-power 9A charger, compared to the typical 2-3A charger typically paired with most e-bikes.

    That’s nothing to do with chemistry. Typical NMC batteries can charge way faster than that.

    Many semi-solid state battery cells already pass the puncture test, in which a nail driven through the cell won’t cause a fire or explosion. Try that with a typical e-bike cell, and, well… you’d better do it in an open and safe area.

    Also not a problem with LFP.

      You are correct but the energy density is half. For this huge bike in the article you probably could get away with it but for a proper small/light ebike LFP doesnt make much sense because they’re so heavy.

          The semi-solid is about 2x of LFP but vanilla lithium cells are about 1.5x of LFP. Its hard to nail down specifics because there are so many flavor of chemistries and designs (high current vs high capacity vs extreme temperatures).
