Silicon Anode Cell Battery Will Save Battery Life
The best choice as a mobile office, laptop and PC, as is also evolving. If the MacBook Air laptop can tell us more light, then the latest research from Stanford University, then to have a stronger notebook battery life, up to 40 hours of usage time is also very scary. Increase endurance because laptop battery using new technology, traditional batteries used in Harima and particle design, the completion of a number of playback cycle will produce loss of the surface, thus causing the endurance of the shrink.
The latest technology uses a tiny metal wire, a match of similar wire rod and the electrolyzer can not only increase the contact area, but also to maintain its original shape. Senior Fellow at Stanford University claim that silicon anode cells may occur within a few years, theoretical data indicate that the battery life can reach more than 10 times the current battery.
Existing lithium-ion battery anode is generally made of graphite, silicon-based anode theoretical capacity of graphite anode of times, but stability is a major obstacle to practical application, and the lithium-ion movement caused by expansion and contraction are easy to make silicon-based anode break failure. Georgia Institute of Technology, Associate Professor Gleb Yushin use of high-temperature tube furnace for carbon black nanoparticles annealed, be branched structure, and then prepared by chemical vapor deposition of silicon particle size of less than 30 nm nanoparticles, and attached to the carbon branched the structure dell battery for vostro 1710. Graphite carbon as conductive adhesives, silicon carbon composites self-assemble into with external openings, interconnected pore structure in the 10-30 m in diameter of the ball, can be used as a battery anode material. Silicon-carbon composite ball ion channels can either allow quick access to improve charging speed, silicon can also provide space for expansion and contraction of the anode without causing rupture. Carbon branched structure and size of silicon nanoparticles determines the size of pore complexes. Changing the reaction duration and pressure, adjustable silicone ball size. In a small button battery test showed that the capacity of the new anode theoretical capacity of graphite anode is more than five times.
Graduate School of Tokyo Institute of Technology School of Engineering Associate Professor Kazuo Atsushi Yamada's group, with the use of high-resolution high-brightness light radiation X-ray powder diffraction (HR-XRD) and other methods, is expected to successfully proved the positive electrode for lithium-ion rechargeable battery material, lithium iron silicate (Li2FeSiO4: lithium, iron, silicon and oxygen) in the crystal structure.
Yamada, associate professor, said, "compared to the original idea, has been informed that the actual crystal structure for the four iron oxide (FeO4) and four silica tetrahedra (SiO4) tetrahedra form one-dimensional chain in the longer cycle regularly followed by rotation of the link structure "(Figure 2). The basic proven lithium iron silicate crystalline structure, so that only the rich resources of the "common elements" consisting of lithium iron silicate can be used as a cathode material, the material design of the benefit is huge. It can be said, suggesting that a low-cost lithium-ion rechargeable battery the road leading to practical use.
Currently, mobile phones and notebook computers use lithium-ion rechargeable battery, the cathode material mainly containing rare element cobalt lithium cobalt oxide (LiCoO2) inspiron 1564 battery pack. But the supply of cobalt raw materials may be unstable, it has been replaced by cobalt in research and development materials. In addition, the thermal stability of lithium cobalt oxide is low, there is a high temperature to generate oxygen (O2) of the problem. Therefore, the lithium-ion rechargeable battery, as the energy per unit volume for non-, but the emphasis on the cost of electric vehicles and power of large-scale battery storage systems, has been developed by low-cost universal elements of the cathode material. Recently, the U.S. venture A123Systems (Massachusetts) developed and marketed a cathode material lithium iron phosphate (LiFePO4) lithium-ion rechargeable battery. Now has been applied to power tools and toys. Japan began importing the batteries for radio controlled model aircraft.
And the crystal structure of olivine-like lithium iron phosphate, compared to lithium-containing elements of two lithium iron silicate used as a cathode material for lithium-ion rechargeable battery is expected to achieve excellent high-energy, but had not proved its crystalline structure.
This time, the research team Yamada, associate professor of basic raw materials of lithium carbonate (LiCO3), ferrous oxalate (FeC2O4 2H2O) and silica (SiO2) powder mixing, argon gas at 1472 Fahrenheit in the sintering 6 hours, made the lithium iron silicate samples. Sample production process, "so do not try to side effects occurred, made hundreds of nm particle size of the sample." X-ray powder diffraction and transmission electron microscopy electron diffraction method on the powder samples were analyzed, verified the complex crystal structure. The crystal structure and electron density analysis of findings.
And compared to existing lithium cobalt oxide, lithium iron silicate closely cobalt and oxygen, is a strong stability of the compounds. Thus, an associate professor Yamada said, "high-temperature decomposition of oxygen when the oxygen atoms are less likely to combustion vostro 1720 replacement battery, as the battery has the advantages of high stability." This is a new Energy and Industrial Technology Development Organization to promote a new generation of storage system strategy for practical technology development projects, the system smoothly storage system technology development cooperation results.
