I'm trying and failing to come up with a use case where this is more practical than a rechargeable (and/or swappable) battery in a scooter. Refueling something like this would be faster than recharging, but if "quick recharge" is part of your requirements then it's straightforward to make a scooter battery swappable and maybe even standardized across brands. Power outlets are ubiquitous, and these things just don't use enough energy to be more than a rounding error on anyone's electric bill (100 (scooter) km worth of energy is roughly the difference between washing your hands in hot water instead of cold water for 30 seconds). There might a weight savings but lithium ion is something like 60 grams per kilometer of range for a light, slow vehicle. So a reasonable range battery is not prohibitively heavy even for a vehicle that you have to carry. I'm sure there's a use case for this stuff, and scooters are trendy right now, but I don't think the two are a good match.
