Digital battery

Have you ever thought one day that the battery will be a paper thin, there is the tenacity to do? It is the dream of many scientists because it can greatly reduce the battery weight and volume of the corresponding electrical appliances. Recently, the University of Uppsala, Sweden Milan Yan and his colleagues have developed an essence of this paper is a new Laptop battery. It is lightweight, slim body, but it is not applicable to devices every day, but it has stores and the airport can be applied to the monitoring. The reason the battery is essentially a paper because it is mainly composed of cellulose.

The researchers stressed that the battery is based on electrochemical principles developed. Each cell has two electrodes immersed in the electrolyte. Typically, the anode of lithium-ion battery cathode carbon cobalt oxide, lithium, lithium salt containing electrolyte compared to the organic solution. When charging the hp 371785-001 battery, electronics will be sucked into the cathode, causing lithium-ion to leave the cathode in the anode. Battery discharge, the process of ion movement is exactly the opposite.

Milan-yen, the American Chemical Society Journal, “Nano Letters” (Nanoletters) a detailed description of cellulose on the battery. Cellulose is an essential component of paper, mainly from trees or cotton, made in the years mentioned but the source of cellulose used in the experiment is different from seaweed extract them all. Milan Yan said they chose to algae because of their cellulose is thinner, which can further enlarge the surface cells, thereby improving the performance of rechargeable batteries.

However, as the cellulose itself is not conducive to be coated with a layer of conductive material cellulose. Milan-yen options, a polymer called polypyrrole, when immersed in the algae with cellulose are then combined to form a conductive material with good performance. Then, the Milan-Yan manufactured with this material cathode and anode of the Dell Inspiron B120 battery. As for the electrolyte, it was used, it is soaked in brine in the filter paper. Therefore, the entire structure of the battery will be a cellulose filter paper sandwiched between two electrodes in the middle, while the electrode was again placed on glass slides. Tape with electrodes of platinum wire connected with the outside world. The energy released by chemical changes have been stored in the polypyrrole. In the process of chemical reaction, molecules generally exist in two states: “oxidized” or “restored” state. To participate in a chemical reaction when the molecule is in the circuit where there will be a current is formed in a second rare, as the completion of a volt rechargeable battery and can load and unload hundreds of times without affecting its performance.

Milan Yan is working to commercialize the technology. Although the current situation and the algae cells can completely replace lithium-ion batteries, but may apply to some of the most appropriate devices, such as installation of equipment containing a small radio. It is noteworthy that recently, some other researchers have also created the transistor with cellulose. Milan Yan battery invention can be applied to these electronic products.
