New eScooter Battery Tech Coming?

Batteries are the chokehold on progress for everything that requires portable power. While everyone else thinks about smartphones, tablets, and computers, I keep thinking about eScooters and eSkateboards — because micro and nano electric transport is where the puck is heading.

From Wired UK, this interesting article — The explosive race to totally reinvent the smartphone battery — with this interesting tidbit:

Voller thinks he can go one better. In 2013, he founded ZapGo, which is developing carbon-based batteries that charge as quickly as supercapacitors, but hold their charge for as long as lithium-ion. By November 2017, it had grown to 22 staff, split across offices at the Rutherford Appleton Laboratory at Harwell, and in Charlotte, North Carolina. Its first consumer cells will be rolling out in third-party products towards the end of this year, including a jump-start kit for cars, and an electric scooter where the charge time is reduced from eight hours to five minutes.

Boldfaced emphasis added by me.

Now hang on. Don’t get all excited yet. Notice that recharge time: Eight hours. That’s beyond what eScooters require today. So he’s not talking about something like this:

He means something like this:

And then comes this WTF bit:

The current, third generation of ZapGo cells aren’t yet powerful enough to run a smartphone, but because the materials used offer no barrier to increasing the voltage, Voller expects to get there by 2022, or “around the iPhone 15”.

So if their battery can’t even power a smartphone, how the hell can it manage a conventional electric scooter? Some information is missing here and I’m guessing that it has to do with the physical size of the battery.

Another reason not to get all excited:

It would require a change in charging infrastructure. The fat bit of your smartphone charger is designed to slow down the amount of electricity flowing into the battery from the grid, to arrest degradation and stop it from catching on fire. Some explosive incidents have been blamed on cheap third-party chargers which don’t have the electronics required to do that.

For ZapGo’s battery, or any supercapacitor-based system, you would need a charger that could do the opposite – store up energy from the wall, and then deliver it to your phone in one short, sharp blast. In the lab, Voller’s team have built something about the size of a laptop power supply, but they’re working to make it smaller and more efficient.

Boldfaced emphasis added by me.

Good luck with that.

Not mentioned anywhere in this report is the Forward Working Group, which has been posting tantalizing videos on YouTube. They’re determined to replace the 18650 batteries used by eCars, eScooters, and eSkateboards.
