New capacitors have very interessting features.
They have a high energy density and recharge very fast.
The currently "best" Supercapacitor was developed by a Texas based company EEstor. The MIT, Japanese companies and others are currently developeing supercapacitors with even more capacity.
The EEstor Supercapacitor has these values:
With this techonolgy it is possible to make a car drive for 300-500km... recharge a few minutes and continue while paying only a tiny price in comparison...
Considering all the things you do not need in a electric car (engine block, cooling, fuelpump/tank,...) I guess it can even reduce the weight compared to a normal car. |
WOW! This is good news.
"The claimed energy density is 1.0 MJ/kg (a lithium ion battery has an energy density of 0.54–0.72 MJ/kg).[2]"
"An initial production price of $3,200, falling to $2,100 with mass production. Half the price per stored watt-hour as lead-acid batteries"
