A team of scientists from Stanford University (EE. UU.) Has developed a battery of high performance aluminum and durability able to charge a mobile phone in under a minute.
The development, published this week in the journal ‘Nature’, is in the experimental stage but researchers emphasize that this battery aluminum could end up being a Alternatively both commercial lithium-ion (the usual laptops and mobile phones) as alkaline batteries.
The aluminum has been a material that has experienced for decades to develop commercially viable batteries, but now a team led by Professor of Chemistry Hongjie Dai has designed a proposed high performance, fast loading and cheaper than lithium-ion.
The challenge was to find a material capable of producing enough voltage after repeated charge and discharge cycles.
The battery has developed two electrodes: a cathode and an anode, which was made with loaded grafito- that were arranged with an ionic liquid electrolyte. The result is able to charge a mobile phone in a minute battery which maintains its capacity for 7,500 charge cycles (before the thousands of standard battery Li-Ion) and bendable , which has potential to be used in flexible devices.
The experimental rechargeable battery generates about two volts of electricity, the largest to date for aluminum, but researchers working higher voltage of one of lithium, which is doubled. “Improving the cathode material could increase the voltage and energy density,” says on the website of Stanford scientist Dai.
The researchers emphasize low flammability -not comes on or when it is perforated, compared to lithium that can go ardiendo- and high capacity to contain high load.
“We have developed a battery of rechargeable aluminum can replace the current ones, such as alkaline batteries, which are bad for the environment, and lithium-ion, sometimes burning out. “
