Heat-resistant lithium-ion rechargeable battery separator

Temperature difference will change the state of e-form current. The thermoelectric conversion phenomenon is called the According to reports, the Japanese professor Shinya Osaka University, Ohio State University, referrals and peer collaboration, the use of lead and tellurium compounds, rare elements and add a small amount of thallium was investigated experimentally. They developed a new material in about 500 ℃ temperature thermoelectric conversion efficiency of more than ten percent, while the efficiency of conventional thermoelectric conversion materials, only 7% to 8%. Researchers said that if the coverage of nano-metal films, new materials, lower temperatures in the high-efficient power generation. In areas such as industrial production,[link widoczny dla zalogowanych], a lot of heat tend to go to waste. For example, ordinary car engine about 60% of the energy generated in the process of generating heat is lost. Shinya Kai said the new material is not expected to make use of wasted energy to a more efficient use,[link widoczny dla zalogowanych], which will address environmental and energy issues play a help. Heat-resistant lithium-ion rechargeable battery separator,[link widoczny dla zalogowanych], Hitachi Maxell has developed a heat resistance of the lithium-ion rechargeable battery with a diaphragm. The diaphragm is the internal lithium-ion rechargeable battery cathode materials and for separating the anode material of the Ministry of material, under normal circumstances, the use of Polyolefin (Polyolefin) made of porous membrane. This time, the project set Maxell in the polyolefin porous membrane made of a plate coated inorganic particles. Compared with normal diaphragm, even at 180 ℃,[link widoczny dla zalogowanych], the phenomenon of the shrinking divide is also very small, you can still maintain its shape. Internal short circuit through the prevention, improved safety performance. The tape manufacturing company to use its accumulated technology, making the shape of the formation of uniform inorganic particles. Increased by controlling the internal resistance, thus inhibiting its output power and capacity reduction. In the polyolefin film coated flat plate arrangement and inorganic particles, even in the case of thin polyolefin film can also be fully maintain its performance. In this way, including those based on heat-resistant layer of inorganic particles, including the thickness of the membrane with the existing ordinary diaphragm reached the same level. Hitachi Maxell plans to market the future use of the heat-resistant membrane lithium-ion rechargeable battery. British study found that manufacturing method of ultra-small pure carbon crystals University of Surrey researchers have found a way to make ultra-small pure carbon crystals of the method, which is entirely spherical carbon The method used involves mixing two liquids together, one of which is contained in the low temperature C60. The new advances may allow researchers to accelerate such a simple manufacturing methods based on nano technology. In the July 28 issue of the British Society of Chemistry, This report describes the preparation of a nano-crystalline fullerene quick and easy way to quickly obtain the width of about 80nm fullerenes diamond crystals, much smaller than a pencil on the l0 times. Has important applications in the future because the value of fullerenes be produced in high yield, and its shape can be by solvent, concentration and temperature changes in control. It should be noted that this study also shows that the existing model of crystal growth of fullerenes need to re-evaluate, because these models predict the minimum size of about 40Ohm, much higher than the research team confirmed 80nm. The small crystals made of the electronic properties of C60 molecules in the development of a new generation of nano-electronic devices (such as too IIii batteries and gas sensors) on the more important. The researchers said that in the control of fullerene nano-scale crystal growth capacity,[link widoczny dla zalogowanych], may lead to some exciting applications. 20
