A group of Northwestern University, Illinois, USA, has developed a nanomaterial that would give greater durability and resistance to batteries in electric cars.
This nanomaterial be able to improve the current system of batteries and super-capacitors that provide the necessary power to the vehicle.
William Dichtel, is the leader of the group of researchers attending Northwestern, explains that the nanomaterial "has the ability to store large amounts of electrical energy or charge, like a battery, and also the ability to be loaded and unloaded quickly, as a supercapacitor" .
The creation of this nanomaterial was given based on a research field that is relatively new the so-called Covalent Organic Frameworks (COF, or organizational framework Covalent in Spanish), a family of highly resistant polymers having a series of tiny pores that allow store energy. They have changed the polymer with a highly conductive material to achieve an alternative to the porous carbon-based electrodes that previously used.
These advances in this research are able to give more autonomy to the batteries, thanks to the developed nanomaterials that combine the attributes of both batteries and super-capacitors, giving a major advance in the technology of electric cars, allowing the duration of the battery charge is greater and so the vehicle can reach more kilometers to go. This certainly leaving cars powered by fossil fuel based off the roads and streets.
"The COFs are impressive and very promising structures, but its conductivity is limited. That's the problem we are trying to solve. To modify and add this attribute lacking COFs can use in practice ".
In a recent demonstration, they found the great potential of its nanomaterial, creating a battery the size of a coin can power an LED for 30 seconds, which represents a considerable but major breakthrough as it demonstrates the viability of these components.
Capabilities present in the material may offer 10,000 cycles of charge and discharge, and that combination of COF with the conductive material allowed 10 times more energy than in the case of the COF unmodified getting an entry will be stored and output electric charge between 10 and 15 times faster.
