London - "Al -Quds Al -Arabi": Scientists have invented the smallest battery in the world through a new technology to use it in the smallest computers used in the hands of people, as it depends on folding micro -small layers, while scientists say it is still "just a primary model at the present time but the results arePrimary encouraging ».
According to a report published by the "Science Alert" website, this new technology comes to succeed the latest and current technology that depends on ultrasound cells or photovoltaic cells to fill small batteries with energy from vibrations or sunlight, with a small storage space.The report quotes scientists as saying that this current technique has its negative aspects, because the computer will not work without a fixed energy source or in dark places such as the human body, which prompted the innovation of the latest technology.The researchers wrote in a recent study: "There is an urgent need to develop high -performance batteries for the millimeter size system and below millimeters because these energy storage systems will facilitate the development of truly independent accurate systems.".Full computer batteries usually depend on "wet chemistry", which means that the metal chips that connect electricity are placed in connection with the liquid electrolyte to generate energy flow.However, the batteries based on chips on a specific scale can support liquid electrolyte.As such, the inventors of this new small battery pressed a solid electrolyte between two small slides, plated with a very thin film of the electrodes, one is positive and the other is negative..However, this solid electricity is not as efficient in the use of liquid electricity, as fold comes.By wrapping a flat battery group in a "Swiss Cylinder", scientists can compress a much larger space in a narrow space.This is the way the cylinders cells work in Tesla electric cars.With the cubic millimeter measurement, it is very difficult to roll thin and fragile materials to this type of shape by external pressure.Fortunately, there is another way to make the material folds on its own, and it is called "small origami", according to "Science Alert".The type of technology works like a rolling window curtain.And when the thin material is pulled down, you can leave this mechanical tension and everything will take up and roll into a cylinder.On a segment, the researchers were able to achieve this movement by installing one side of the thin material to create in essence, a wind window.In the end, the team was able to collect a preliminary model of the small battery in an area not exceeding 0.04 millimeters, which provides eight times higher.The researchers say that the cylinder is similar to the standard structure of the Swiss scraps used in the largest batteries, including at least two layers for the complex, Anudi tape, and electrolyte membrane together..The researchers say the design is not only recharge, but the battery in its current position can operate our youngest computers for about 10 hours..There is still more work to do."There are still tremendous potential to improve this technology, and we can expect much stronger microbiology in the future," says physicist Oliver Schmidt of Kimins Technology University in Germany..
