Recently, Swedish scientists have used cellulose produced by algae, laptop battery,like paper-thin, lightweight, flexible battery can be used to track products from the origin to the shelf’s whereabouts, or used to track baggage through the airport security whereabouts. Related research published in the latest issue of “Nano Letters” on.
Electrochemical reaction on the work of the battery, each cell contains two electrodes (cathode and anode), the two electrodes immersed in electrolyte. Now widely used in mobile phones and laptop computers in the lithium apple a1060 battery,apple a1061 battery anode from the carbon composition of lithium cobalt oxide cathode by the constitution, dissolved organic lithium salt containing electrolyte. When the battery is when you pass on the power electronic North Korea embarked on the cathode, forcing positively charged lithium-ion away from the cathode into the anode, when the battery discharge, the current from the anode for lithium-ion to return to the cathode.
Albert Te Milan Uppsala University in Sweden and his colleagues invented a result of the apple a1078 battery,apple a1079 battery from the seaweed extract made from the cellulose (paper is extracted from trees or cotton, made from cellulose). Algae cellulose fiber is more slender, make a larger surface area of the battery so that it can store more charge.
However, the fiber itself is not conductive, Milan because of the team using a common conductive polymer polypyrrole (polypyrrole) to surround fiber. Polypyrrole is usually amorphous black solid, insoluble does not melt at 200 ℃ when the decomposition can be conductive. The researchers report their submerged algae fibers, resulting in a mixture can be conductive. Then, they are in such compounds in the manufacture of a new apple a1148 battery,apple a1175 battery poles, using filter paper soaked in salt water as electrolyte.
The new cell consists of two cellulose electrodes and caught in the salt-impregnated filter paper composition, looks like a sandwich, two cellulose electrodes located in between two glass slides. Poles attached to the platinum with the formation of conductive contact with the outside world. In the polypyrrole chemical changes occurred in storage and release of power, in which the molecules exist in two forms, that is the term called “oxidation state” and “restore state”, when these two states of the molecules to form loops, that is to generate electricity. The apple a1185 battery,apple m8403 battery can be charged within a few seconds, but after 100 charge-discharge performance does not appear large losses.
Dr. Milan are due to find a business for this scientific and technological achievements “mother.” At present, the efficiency of algal cells is only one-third of lithium-ion battery, which although not a substitute for lithium batteries, but there are also a unique display their abilities, can be used with a small radio devices, luggage tags, using the signal to Luggage regulators to track the location of baggage; also be used for “smart” packaging materials, such as with electronic display box. In addition, Dr. Milan apple ibook g4 12-inch series battery,apple ibook g4 14-inch series battery can also be due to the recent successful development of the transistor components of paper-based charge.
