In 30 Seconds: New Battery Breaks Patterns

March 5 2018 9

The most common problem of modern powerful smartphones is the high energy consumption, and therefore the rapid discharge of the battery.

On the one hand, this limits the power growth of portable devices; on the other hand, it forces engineers to upgrade and strengthen compact power supplies. And while some increase energy consumption and optimize consumption, South Korean scientists decided to go on the other side and developed an ultra-fast charging battery.

Researchers at the Higher School of Energy under the leadership of Professor Ching Ku Kang have combined fiber-like polymer chains and metal oxide nanocathodes on the surface of graphene, taken as the basis of the product. The choice of graphene as a base is justified by the fact that the structure of this material provides an increased storage area, and therefore increases the battery capacity. The resulting battery can be charged even using a low-power USB-connector in just 20-30 seconds.

In 30 Seconds: New Battery Breaks Patterns

In addition to ultra-fast charging, the advantages of this invention include the long service life, high environmental friendliness of conventional batteries, and the ease of production, which allows us to hope for the arrival of this miracle soonequipment into mass production.

And what, someone canceled the law of conservation of energy? If you have a battery capacity of 3 mAh - then you will charge it 000 And no less than an hour! As the charge time decreases, the current will increase! And which connector can it stand?

  but the devil knows him. maybe it's in graphene. it is necessary to read its properties

    I believe that graphene is interesting tnm that it has a high surface area that can take charge. But this may mean that if there is an excess of charge entering the surface, graphene will tend, as it were, to find the optimal total charge surface. Therefore, there is a probability of a change in the structure of graphene. Magnetic interactions can be very strong. This all requires research. But there is another way. This is the creation of asymmetric polarization systems in design, and, moreover, batteries with a multipolar system of cathodes and anodes.

3 mAh is about 000-10 Wh, i.e. in order to ensure charging of this battery in 12 hour, it is necessary to bring the power of 1 W, for a minute - to cram the power of 12 * 12 = 60 W into it, and for charging in 720-20 sec, a source of 30-1500 W is already needed.
usb3.1 in theory up to 100W shakes. But they still have to manage to accept. That is, in theory, usb3.1 is capable of charging this battery in 6-10 minutes.

  Here the question is still in contacts: how and which of the available common connectors can pass such an amount of low-voltage energy and not melt at the same time? Here, at a minimum, you need silver with a good area of reliable contact. Copper is already quite worse.

    Yes, I myself do not care! USB3.1 to 5A for what kind of wiring and also contact hair.

  It just uses the ideology of the process as it happens in the capacitor. That is, charging can be carried out almost instantly, and graphene is used as a solid electrolyte but with the task of braking, rather than active ion transfer. Therefore, we say that the battery can be created from the same material for the cathode and anode and in one structural element, but its surfaces can mate for example with an acidic medium and the other with an alkaline one. I note that graphene is dangerous in that it is a catalyst for high-temperature processes. Therefore, it will contribute to ignition, especially in an environment saturated with oxygen.

The resulting battery can be charged. even using a low-power USB connector in just 20-30 seconds.
Can zhurnalyugi misunderstood something again?

Few people focus on the fact that all power sources have a very low energy density of the cell or one part of the polarization. Therefore, it is not possible to create, for example, a battery in one cell at once, for example, 24 volts. But we found such a solution that allows us to radically increase precisely the energy density in one cathode-anode part of the interactions.
