U.S. scientists have invented a cheap, long-lasting and flexible battery made of aluminum for use in smartphones that can be charged in as little as one minute.It is both greener and safer. We the people easily getting frustration of waiting hours for our smartphone or tablet to fully recharge. So this is the great news for, who are all having an above experience of frustration.
Safety is one thing, but the move to aluminum with a graphite cathode has other benefits. Aluminium is cheap, light, flexible, low flammability and high-charge storage capacity,has a lower environmental impact.
The new high-performance aluminum-ion battery is the first using the metal – more commonly found in aircraft and car bodies. It does this using a graphite electrode. The prototype created at Stanford University reached7,500 charge-discharge cycles without any loss of capacity but previous aluminum batteries have suffered from poor life, failing after 100 recharge cycles.
Hongjie Dai, a professor of chemistry at Stanford University said, we have developed a rechargeable aluminum battery that may replace existing storage devices, such as alkaline batteries, which are bad for the environment, and lithium-ion batteries, which occasionally burst into flames. Our new battery won’t catch fire, even if you drill through it.
Conventional alkaline batteries are bad for the environment while lithium-ion batteries used in millions of laptops and smartphones can unexpectedly burst into flames and take a long time to charge.
In a breakthrough Stanford University has invented the first high-performance aluminum battery that is fast-charging, long-lasting and inexpensive. It is also flexible too so can be used in new folding devices in development.
There is one issue that needs to be solved before the battery goes into mass production — while the Stanford team’s battery offers voltage higher than any other aluminum-based battery, it’s still lower than the voltage of your average smartphone lithium battery, which is typically 3.7V or 4.2V.
Presently the rechargeable aluminum battery generates about two volts of electricity, the highest achieved yet with aluminum.But our researchers explained the battery has a limited voltage, compared to existing technology.Our battery produces about half the voltage of a typical lithium battery, Professor Dai said: By improving the cathode material could eventually increase the voltage and energy density.I see this as a new battery in its early days. It’s quite exciting.
- Aluminum battery from Stanford offers safe alternative to conventional batteries.
- It is more environmentally friendly than alkaline batteries, and can’t catch fire like lithium-ion technology.
- Aluminum batteries are used to store renewable energy on the electrical grid.
- The grid needs a battery with a long cycle life that can rapidly store and release energy,” he explained. “Our latest unpublished data suggest that an aluminum battery can be recharged tens of thousands of times. It’s hard to imagine building a huge lithium-ion battery for grid storage.
- The prototype created at Stanford University reached 7,500 charge-discharge cycles without any loss of capacity but previous aluminum batteries have suffered from poor life, failing after 100 recharge cycles.
- Improving the cathode material could eventually increase the voltage and energy density.
- “Millions of consumers use 1.5-volt AA and AAA batteries,” he said. “Our rechargeable aluminum battery generates about two volts of electricity. That’s higher than anyone has achieved with aluminum.”
- lithium-ion batteries can take hours to charge, the new battery has ‘unprecedented charging times’ of down to one minute.
