Is it the last piece for the breakthrough of electric cars ?

Critics always mentioned the point that electric cars need a long time to be charged and destinations far away are impossible to reach in a reasonable time. Another reason why critics see electro car are failed, are the high costs of the battery.
Tanktwo, a Finnish-American start-up company, may found the solution for both problems. With their idea, it is possible to “charge” an electro car within 3 minutes and the battery system is low on cost.
But how is this possible? The answer is string batteries. Tanktwo offers with their idea a complete new battery system.
Tiny egg shaped batteries are filled in a tank. Every battery contains a lithium-ionic-cell and a processor. As soon as some batteries are together in a closed container, they start to be an independent battery network. The arrangement of the batteries is irrelevant. If the batteries are low on energy, there are two possibilities to charge the car. The first one is to charge the battery at a charging station, like we already know. The second one is to change the empty batteries and replace them with fresh ones at a “service station”. This exchange takes just 3 minutes.

Everyone can decide how many “egg”-batteries should be filled in the tank (as it is with normal petrol). It would also be possible to have different qualities of “egg”-batteries. Old batteries could be replaced with new developed ones.
As innovative as the idea is, we have to take into consideration that the batteries contain lithium. The extraction of lithium cause a lot of pollution and environmental damage.
