The Israeli company Storedot has reportedly developed a prototype for a new battery technique that can charge the battery of a mobile phone in 30 seconds. Senior researcher at DTU Energy Poul Norby finds the battery and the new charging technique promising, but it is still no more than on a prototype.
"It sounds very promising, but we already have materials that can be charged as fast, and we have too few details of the technology to definitely say how good this Israeli technology really is," he told the host of the television show DR2 Dagen, Lene Johansen.

Batteries of today are mainly lithium batteries, and they are actually pretty good, said Poul Norby, but if we are to look further ahead on the needs of energy storage for transportation, electric cars and short-term storage of power, so we have to consider cost, energy density and charging rate.
“That is why we see such interest in this technology”, said Poul Norby.
International investors have, according DR2 day, invested about 48 million Dollars, equivalent to over 300 million Kroner in the new Israeli technology, but so far the technology is limited to a prototype.
"It will take several years before we can finally evaluate the technique," said Poul Norby.
He did, however, tell the television host that there are a lot of money to be made on batteries, as one can hardly imagine a future where energy storage is not an essential necessity.
"Today's technology can be used, but the challenges are getting bigger and the essential tasks are to get the price of the batteries down and to compress the energy while lowering the weight," said Poul Norby.
"It is a nuisance when a mobile runs dry, but electric cars require a better battery technology. This is why we need to give battery technology a kick, and this Israeli technology might help doing that. "
