Typical hype in the link, there is no free lunch in physics or chemistry.
I reviewed a Li polymer battery claim 15 years ago, 'inventor' said he could charge a 270Vdc 100 AH battery in 2 minutes from a 120V, 15 A wall outlet. Violation of about every known law of conservation of energy. Ha! Guy used wall outlet to charge a 1000A-hr battery bank, then hooked that in parallel with the discharged 100A-hr battery and called that 'charging from wall outlet'. Probably a 2 cycle battery life at that charging rate.
Charge rate comparison to filling your gas tank.
20 gal of gas into a tank in say 6 minutes
25% efficient car engine
20 gal = approx. 2.5 million BTU, at 25% = 625,000 BTU
divide by 3412 = 183 kW-hrs; or for a 100% efficient 300Vdc electric car battery, 610 Amp-hrs
6 min = 0.1 hours
power supply to charge a hypothetical 300Vdc, 610 A-hr battery in 6 minutes = 1.8 megawatts. Not including losses.
edit ps: there are aluminum 'battery' schemes where a plate of aluminum reacts and is consumed, recharging is sliding in a new aluminum plate, the 'recharge' is done at the aluminum smelter.
