Selection Of Battery Materials For Lithium Battery

    "Lithium Battery" is a kind of lithium-metal or lithium alloy anode material, the use of non hydro-electrolyte solution of the battery. 1912 Lithium-metal batteries were first proposed and studied by Gilbert N. Lewis. In the 1970s, M. S. Whittingham proposed and began to study lithium-ion batteries. Because the chemical characteristics of lithium metal is very lively, making lithium metal processing, preservation, use, the environmental requirements are very high. Therefore, lithium batteries have not been used for a long time. With the development of science and technology, lithium battery has become the mainstream. Lithium batteries can be broadly divided into two types: lithium-metal batteries and lithium-ion batteries.Lithium Battery
    Lithium batteries are used in pacemakers at the earliest stage. Lithium-ion batteries have very low self-discharge rates and a smooth discharge voltage, which makes it possible for a pacemaker implanted in the body to operate without recharging. Lithium batteries generally have a nominal voltage higher than 3.0 volts, more suitable for integrated circuit power. Manganese dioxide batteries are widely used in calculators, digital cameras, watches. In order to develop more excellent varieties, people have studied various materials, so as to produce unprecedented products. 1992 Sony successfully developed lithium ion battery. Its practicality, so that people's mobile phones, notebooks, calculators and other portable electronic equipment weight and volume greatly reduced.
Lithium-ion batteries do not contain metal-state lithium, and can be recharged. The fifth generation lithium-metal battery of rechargeable Battery was born in 1996, its safety, specific capacity, self-discharge rate and performance price ratio were better than lithium-ion battery. With its own High-tech requirements Limited, only a handful of companies are now producing lithium-metal batteries.Lithium Battery
    Carbon anode materials have been actually used in lithium ion battery cathode materials are basically carbon materials, such as artificial graphite, natural graphite, mesophase carbon microspheres, petroleum coke, carbon fiber, pyrolytic resin carbon. The tin-like anode material can be divided into two kinds: sn oxide and tin base compound oxide. Oxides are oxides of various valence metal tin. No commercial products. Nitride also has no commercial products. Alloys include tin-based alloys, silicon-based alloys, germanium alloys, aluminum alloys, antimony-based alloys, magnesium-based alloys and other alloys, and no commercially available products. Nanometer carbon nanotubes, nano-alloy materials. Nano-oxides at present, according to the 2009 New energy industry market development trends, many companies have begun to use nano-titanium oxide and nano-silica to add in the traditional graphite, tin oxide, carbon nanotubes inside, greatly improving the charge and discharge of lithium batteries and the number of charge and discharge.Lithium Battery
