This new battery can be charged within seconds!  -  battery energy storage
Scientists have developed a new self.
Assemble the battery device, which can be charged in a few seconds and powered for future mobile devices.
Researchers at Cornell University in the United States have created a new battery structure to meet the needs of energy storage devices that can charge faster.
Instead of placing the anode and cathode of the battery on either side of the non-conductive separator, They interweave the Assembly
Assembly, 3D gyro structure, with thousands of nanometers of holes, is filled with the elements needed for energy storage and delivery.

"The Dimensional architecture basically eliminates all the loss of dead volume in the device," said Ulrich Wiesner, a professor at dimenfeld . ".
"More importantly, as we do, reducing the size of these mutually infiltrated areas to nanometers will bring you an order of magnitude higher power density.
In other words, you can get energy in less time than the traditional battery structure, "Wiesner said.
Since the size of the battery element is reduced to nano scale, "Maybe faster in a few seconds when you put the cable into the socket," he said: "The battery will be charged . ".
The architecture of this concept is based on polymer
Components used by the Wiesner group for many years on other devices, including gyro solar cells and gyro conductors.
Joberg Werner, the lead author of the study, published in the journal Energy and Environmental Science, has tried himself.
Assemble the photon device and wonder if the same principle can be applied to the energy storage of carbon materials.
Carbon-thin film
The anode of the battery is unique from oneassembly -
Thousands of periodic pores are presented in the order of 40 nm wide.
Then coat these pores with 10 nm
Electronic insulation but thick ion
The separator is carried out by electric polymerization, and the essence of the electric polymerization process creates a small hole-
Free separation layer.
Defects such as holes on the separator can cause catastrophic failures, causing mobile devices such as mobile phones and laptops to catch fire.
The next step is to add cathode material-
In this case, sulfur
Do not fill the amount of the remaining part of the pores.
Since the sulfur can accept electrons but is not conductive, the last step is to backfill with an electronic conductive polymerknown as PEDOT.
The group is still refining the technology, but applied for patent protection on the evidence. of-concept work. .
