Scientists from the Polytechnic University of Valencia (UPV) have developed electrically charged devices for textile materials.
These devices are basically ‘supercondensers’ placed on active carbon tissues that stand out due to their electric properties and high level of power.
According to the scientists, incorporating these devices into textile materials could one day keep our mobile phones charged on the go.
The UPV study focuses on using textile materials as electrodes.
The devices designed and tested by the scientists use active carbon, graphene and polyaniline – a polymer with high capabilities that is already broadly used in textile materials.
As part of their study, the scientists evaluated different strategies that obtain electric charge accumulators from the electrochemical reduction of graphene oxide on the surface of the activated carbon.
“We have obtained new electric charge accumulators with specific power that are very competitive, and which could be used to charge the batteries of several devices,” intones Francisco J. Cases, head of the GESEP.
“The supercondensers have been developed on textile materials, and therefore, the volume/mass and surface/mass ratios are very high.”
According to José Antonio Bonastre – also from GESEP, the new devices can withstand 1,000 charging and discharging cycles with no problem.
This equates to three years of the daily charging and discharging of a mobile phone.
The supercondensers could also double up as an alternative to lithium batteries or fuel cells.
“The tests we have conducted in the laboratories prove that our devices have a specific power that is very competitive,” says Bonastre.
“In the case of fuel cells, they range from 2 to 200 W/Kg, and in the case of lithium batteries, from 100 to 600.”
This aside, the team’s active carbon, polyaniline and graphene supercondensers reached powers of 500 W/Kg.
They can also be used to treat waste water by way of electrolysis, notes Cases.
