New technology helps to fully charge the battery in less than 30 seconds

Scientists have recently invented an active energy storage device based on electrolyte solution. This is the perfect device for mobile electronics that need regular and quick electrical power supply.

This idea is not new, but it gets everyone's attention because similar devices that previously provide low power and have very low life expectancy. Today, the demand for energy storage technology is increasing. Accordingly, the device must not only be compact, strong, large capacity, but also have a long life but must also provide electricity quickly and environmentally friendly. Even if you accidentally swallow it, it doesn't matter.

For many reasons, storage devices based on electrolyte solutions are considered to be safer and more reliable than those containing toxic or combustible organic compounds. The new device possesses many outstanding features such as less ignition than modern lithium batteries, is cheaper and especially provides abundant power.

The components that make up the battery work by transferring electrons between the two materials. And devices that contain aqueous solution limit the voltage range between two points more than other devices, making the terminals erode faster. This makes devices with short lifespans and low power efficiency. This is also not a reliable tool for charging smart devices recently released.

Therefore, researchers at the Korea Advanced Institute of Science and Technology (KAIST) have made many new improvements. They changed the way of making devices called water capacitors (AHC). Hybrid capacitors like this are a combination of batteries and capacitors - with the electrode storing electricity as an electrostatic charge. In addition, the device also contains a mixture of ion-bearing water in the middle that can carry current.

The researchers overcame the lack of power of previous water capacitors by using polymers made from graphene instead of traditional metal conductors on the anode, while on the cathode there is fecundity. canopy of metal nanoparticles.

The network of small carbon fibers on the anode is much more efficient in transferring electrons to aqueous solutions. They allow the battery to store 100 times more power than previous devices but still maintain a capacity for more than 100,000 charges. What's even more amazing is that the anodes combined with electrolyte fluid help the battery power to switch from 0 to 100 within 20 seconds of charging. In addition, the device is also very safe and economical.

Chemist Jeung Ku Kang said: "This eco-friendly technology can be made easily and has a high degree of application. Especially, compared to existing technologies, the device has merit. high productivity and stability, which can help water capacitors to be commercialized more widely. '

Compared to photovoltaic cells or other sources of microbial energy generation, the device's charging speed can be doubled easily. It will take some time for the new technology to outperform lithium ion batteries, but the components in the device will be able to withstand harsh conditions without burning. And surely it will have a strong foothold in mobile technology in the future.

Although new batteries meet our requirements, it does more than that. Low charging time is just another plus because the magic graphene materials are much superior. Samsung Group has discovered its potential and may in the future launch a smartphone that can fully charge the battery in about 12 minutes.

It is unknown whether fast-charging batteries are suitable for this new storage technology, but with the rapid development of smart devices today, we will need many useful inventions like this. half.
