Nog niet makkelijk leverbaar, prijs.. geen idee.. Maar het belooft wel wat.

Stond overigens zeer verbaasd te kijken toen ik las dat deze technologie komt tot 100 vierkante meter oppervlak per gram anode materiaal...

Groot voordeel van deze cellen is de vermogens dichtheid, de grote 'veilige' laad en ontlaad stromen.
Kwa specs zitten ze tussen SuperCaps en Lifepo4 in.
Deze zijn ondertussen wel vergelijkbaar met de huidige RC-lipo generatie (die zijn wel niet zo 'veilig').

Groot nadeel is het lage voltage (2,4V) en de resulterende lage energie dichtheid (+/- 65Wh/kg).

Is Lithium ondertussen niet steeds schaarser aan het worden?

Ow volgens wiki kunnen we nog even :

However, according to a 2011 study conducted at Lawrence Berkeley National Laboratory and the University of California Berkeley, the currently estimated reserve base of lithium should not be a limiting factor for large-scale battery production for electric vehicles, as the study estimated that on the order of 1 billion 40 kWh Li-based batteries could be built with current reserves.[82] Another 2011 study by researchers from the University of Michigan and Ford Motor Company found that there are sufficient lithium resources to support global demand until 2100, including the lithium required for the potential widespread use of hybrid electric, plug-in hybrid electric and battery electric vehicles. The study estimated global lithium reserves at 39 million tons, and total demand for lithium during the 90-year period analyzed at 12–20 million tons, depending on the scenarios regarding economic growth and recycling rates.[83]
