According to foreign reports, U.S. researchers said they invented a light paper battery that can be used as a power storage device for the next generation of consumer electronic equipment.
This battery generates electricity in the same way as the traditional lithium ion batteries currently used in many electronic products. However, all the components of this battery can be combined into a light and flexible paper.
The early prototype product is only as large as the distance between the thumb and the forefinger, which can emit 2.5V, enough to drive a small fan or light a lamp. The inventor of this kind of battery said that this kind of battery can be upgraded to provide the power needed to run many electronic devices.
Robert Linhardt, professor of biology and chemistry at rensler Institute of Technology in New York, is a member of this project team. He said, you can put a piece of paper on another piece of paper to improve the power output. We have tested with 10 sheets of paper and nothing can prevent you from using 500 sheets of paper. This paper battery can bend or fold into any shape you like. The design function of this paper battery is endless.
As manufacturers add more and more features to smaller and smaller devices, the pressure on components is reduced as much as possible. In many cases, batteries remain the largest component in electronic equipment.
Scientists from rensler Institute of Technology used tiny carbon nanotubes to channel electrodes in traditional batteries and used ionic liquid solutions as electrolyte. These two components are used for conducting electricity. They use cellulose or paper as a separator, which is the third important component in the battery.
This kind of battery can work in the temperature range of 300 degrees Fahrenheit to minus 100 degrees, and can be used as battery or supercapacitor. In addition to laptops, mobile phones or digital cameras, this kind of battery can also be used in cars, planes and ships due to its light weight.
The materials used in this battery prototype product are not expensive. However, researchers are still studying ways to produce this paper battery at a lower price. They hope to be able to print this paper battery like a roll-type system printing newspaper in the end.
