Full article link below, but references same battery capacity (ie range) but lighter cheaper more easily sourceable components, with faster charge time. The example given is a Nissan Leaf charge time reduced from 4 hours to 12 minutes!

Happy reading all.

I disagree Mr Hedgehog. You can drive for fun with an electric Powertrain, could be powered by magic for all I care - the proof of the pudding is in the eating as they say.

Elon Musk must be pretty confident in the future of Lithium-Ion batteries considering he's about to sink $5 billion into a new production facility.

heck yeah, all electric cars are dull, Heaven forbid if you got stuck with one of these:




or one of these:




or one of these:





Now, while you can say "yeah, but those are all hypercars i can't afford" in 5 or 10 years, your typical family car will be leveraging similar technology!!

The good thing about EV is the motors don't cost that much - so you could thortically get a 400 bhp Motor for a few thousandd. It's the batteries that cost a lot. So buy one now with a 50kWh battery pack. and when the new 12 minute charging 200kWh pack is available for £3,000 then upgrade. Beats having to buy a whole new car.

Go and try and buy a P1 Emachine of MESL and see how you get on!

Like everything, it is the production volumes that fix how much something costs. Mass produced ICEs are also cheap. Low volumes ones (like race engines) aren't, even though they use the same amount of material and number of parts! High performance Emachines are expensive to make, particularly as the power and efficiency of the machine depend upon the magnet material spec and the winding density (copper fill) In both cases, better = more expensive, particularly for the windings, where moving to a hand wound stator brings several % points improvement in the losses, but costs a fortune..........

I was reading the article and what primarily hit me is that it was an advertorial and the product it was selling was not the battery but Power Japan Plus. It's the kind off article that you have written and then seed into the media to act as 'third party' confirmation when you go out to raise money.

Sure enough they are a start up. And the product the are selling is equity not batteries.

Doesn't mean they don't have a battery product but it does mean that I personally have consigned it and them to the bin.

And what is the chemical symbol 'A' all about in the diagram?

"Anions" - AKA negatively charged ions (which are attracted to the cathode).
