New type of battery charger for smartphones less than 1 second

(Smart phones) - Smart phones are becoming more sophisticated than ever, but so far, their batteries are still relatively 'old'.

Scientists at the University of Illinois have been working to develop an extremely small battery that has been created, making them about 1000 times more powerful than lithium (Li) batteries and paving the way for smartphones to charged in just a second.

'This is a whole new way to think about batteries,' said lead researcher William King.

These new batteries have a three-dimensional internal structure thanks to their high performance. Like all batteries, they have two main components - anode (anode) and cathode (katot).

Based on an incredible ultra-fast sound design, scientists have developed a suitable anode and then created a new way to integrate these two components into a very small layer to create a lump Complete battery with high performance.

These batteries can connect sensors or radio signals 30 times longer, or devices 30 times smaller.

These batteries are rechargeable and can charge 1,000 times faster than other competing technologies.

Theoretically a slim card phone can be charged in less than a second.

'A battery can provide more energy than anyone ever thought of,' said William King. 'In recent decades, electronic devices have been more compact. The processing parts of the computers were more compact, and the battery was lagging behind. This is a micro-technology that can help change that. Now the power supply (batteries) is as efficient as other parts'.

Until recently, users still had to choose between capacity and energy.

For applications that require high power such as radio broadcasts over a large distance, capacitors can release energy very quickly but capacitors can only store a small amount.

For applications that require a lot of energy, like running a radio for a long time, fuel cells and batteries can contain a lot of energy, but they take a long time to charge.

'It's (always) a sacrifice , ' said James Pikul, a graduate student and the first author of the article.

'If you want high energy, you can't have a high capacity; If you want high capacity, it is very difficult to get high energy. '

'But for interesting applications, especially modern applications, you really need both things'.

'That's what our batteries are starting to do. We are actually entering the area in the energy storage design space not currently in today's technologies. '

Because old-style batteries have poor capacity, modern phones often need to charge.

The new micro-battery (microbattery) provides both capacity and energy, and by gently changing the structure, researchers can refine them, and thus have a better compromise between work. power and energy levels.

Mobile phone batteries are often the most common cause of nuisance because of their short lifespans.

Building on a new quick charging cathode designed by Professor Paul Braun, King and Pikul's team developed a suitable anode and developed a new way to integrate these two poles in a small plate to create Get a complete battery with high performance.

In addition to consumer electronics, medical devices, lasers, sensors and other applications can go through great leaps in technology with the above available power sources.

'So far, any kind of electronic device is limited by the size of the battery , ' King said.

'Look at personal medical devices and implants, these devices have batteries that are a big lump and are connected to tiny electronic devices and tiny wires. Now the battery is tiny '.

Researchers are currently working on integrating their batteries with other electronic components, as well as reducing the cost of producing them.

'We can now think further,' says Pikul. 'This is a new technology. It is not a technological improvement through the existing technologies, it breaks the usual patterns of energy sources. It allows us to do differently, to do things that are really new. '
