ReVolt, BASF Sign Zinc-Air Battery Development Deal - lithium air battery
By Jeff St.
JohnSwiss startup ReVolt Technology will get help from chemical giant BASF in the commercial of rechargeable zinc
The two companies announced air batteries on Thursday.
The financial terms of the deal have not yet been announced, but BASF said it will put engineers on the task and provide materials and subsystems, to "help BASF assess the current and future potential of this technology ". "Metal-
Air Batteries generate electricity by exposing metals and electrolyte to oxygen, oxidation of metals and releasing energy (see electricity from air and zinc?
More and more chorus say yes.
They can provide multiple times the energy density of lithium.
But charging them is a challenge because the chemical processes they use to generate electricity are difficult to reverse.
This limits their commercial appeal to singles.
Use hearing aid batteries and other purposes.
ReVolt said it solved the charging problem with bi
Functional air electrodes that can be modified to drive oxygen and metal for the first reaction with more energyefficient way.
It also doesn't reduce the material involved, it says, which leads to a rechargeable battery with about three times its lithium storage capacityion contenders.
The insurgency caused € 10 million ($14 million), an increase of € 2005 and € 7 million in funding in January 2.
5 million seed round financing.
In the process of looking for rechargeable metal, it is not alone --air battery.
Lawrence Berkeley National Lab spin-off PowerAir has what's called Zinc
Air Fuel cells, because they are like fuel cells, "charge" by removing waste materials and adding fresh materials ".
It is also looking for ways to use the remaining zinc oxide. Lithium-
Air cells can provide a greater energy density, the researchers said. Berkeley-
Based on the fact that the startup PolyPlus is developing lithium air batteries, as well as batteries that use seawater or sulfur as an electrolyte, it says its "protected" lithium electrode makes it possible, these electrodes are not chemically mixed with the electrolyte.
According to CNET, the company is developing Lithium
A lithium battery with an air battery of Quallion.
Ion battery manufacturers with medical equipment and military customers are now looking to expand to power the idling truck (see Quallion for DOE funding)
Battery ).
IBM is also working on lithium.
Air Battery, look at the way it develops filters for water purification at the Almaden Research Center in San Jose, California
, Can be applied to charging challenges (see IBM's research on lithium
Water-air battery
Super computer for cooling ).
ReVolt will be one of the 25 European and Israeli green tech start-ups that will be presented at the European tech tour clean tech summit next week (see green light post).
There may be more details about its commercial plan.
