With our ‘smarter’ phones, one major problem that we have right now is on the battery. Li-ion batteries, which are in most smartphones, could only last for a day or two in an hour or more of charging time. We even published an article recently, regarding the tips to make our phone battery last longer. However, these tips won’t make our battery last for a week on a single charge, unless if we power it off most of the time.
But, now, we have a new hope.
Researchers from the University of Central Florida developed a new type of battery that lasts for several days and charges in seconds. Amazing, and perhaps unbelievable, but it’s actually real and tangible.
The new battery
The high-powered battery developed by the researchers is packed with supercapacitors that can store a large amount of energy. The battery is small, thin – more like the size of a fingernail – but it is much powerful that it can be used in phones, wearables, and even in electric vehicles.
Aside from that, it stores energy rapidly, and can be recharged more than 30,000 times.
Lithium-ion batteries vs. high-powered battery
Normal Li-ion batteries only be recharged in a few hundred times, probably, between 300 to 500 full charges, and then, they begin to tire- dropping to 70 percent of the original capacity. Although other estimates claim that some batteries can withstand up to 7,000 charges, the new battery is still the best – at 30,000 times. Compared to the current Li-ion batteries, this new technology is very promising.
“If they were to replace the batteries with these supercapacitors, you could charge your mobile phone in a few seconds and you wouldn’t need to charge it again for over a week,” said Professor Nitin Choudhary, one of the researchers behind the new technology.
The high-powered battery and its configuration
Supercapacitors are used at a large-scale. Hence, it was not being utilized as batteries. However, the researchers were able to devise a very effective way to overcome this difficulty. They use tiny wires that are nanometer thick and coat it with high-energy shell. The core of the wires is highly conductive, allowing superfast charging – charging in seconds.
“For small electronic devices, our materials are surpassing the conventional ones worldwide in terms of energy density, power density and cyclic stability,” said Prof Choudhary. Cyclic stability refers to the number of times a battery can be fully charged and drained before it starts to degrade.
What lies ahead?
Right now, the battery isn’t available in consumer devices. However, this is a very good position for a brighter future in terms of the battery technology. Sooner, batteries won’t be a major problem on smartphones.
If Li-ion batteries will be replaced with this new technology, our phones will have long lasting batteries. In addition, we will be able to get rid of the problems with the Li-ion batteries, particularly, on its tendency to overheat and cause explosion – as what happened to Samsung Galaxy Note 7.
So, do you think this technology is something that we can look forward to in our smartphones? Are you willing to invest on smartphones with the high-powered battery?
