Lithium batteries have applications in many long-life devices, such as pacemakers and other implantable electronic medical devices. These devices use special lithium-iodine batteries designed to last 15 years or longer. However, for other less important applications, such as toys, lithium batteries may have a longer life than the device. In this case, expensive lithium batteries may not be cost-effective.
Lithium batteries can replace ordinary alkaline batteries in many devices, such as clocks and cameras. Although lithium batteries are more expensive, they can provide longer life, thus greatly reducing battery replacement. It is worth noting that if equipment using ordinary zinc batteries is replaced with lithium batteries, attention must be paid to the high voltage generated by lithium batteries.
Lithium batteries are also widely used in instruments and equipment that require long periods of use and where the batteries cannot be replaced. Small lithium batteries are often used in small portable electronic devices such as PDAs, watches, video cameras, digital cameras, thermometers, calculators, computer BIOS, communication devices, and remote car locks. The high current and high energy density of lithium batteries, and the ability to maintain high voltages for longer periods of time than alkaline batteries, make lithium batteries a particularly attractive option.
"Lithium batteries", a class of batteries made of lithium metal or lithium alloy as the anode material, using a non-aqueous electrolyte solution. lithium metal batteries were early proposed and studied by Gilbert N. Lewis in 1912. in the 1970s, M. S. Whittingham proposed and began to study lithium-ion batteries. In the 1970s, M. S. Whittingham proposed and began to study lithium-ion batteries. Due to the chemical properties of lithium metal being very active, making the processing, preservation, and use of lithium metal, 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 batteries have now become mainstream.
What materials can be used for lithium battery materials?
1), carbon cathode material
Has been actually used in lithium-ion battery anode materials are basically carbon materials, such as artificial graphite, natural graphite, intermediate phase carbon microspheres, petroleum coke, carbon fiber, pyrolysis resin carbon, etc.
2) Tin-based anode materials
Tin-based negative electrode materials can be divided into two kinds of tin oxides and tin-based composite oxides. Oxides are oxides of various valence metal tin. There is no commercialized product.
3)、Nitride
4)、Alloys
Including tin-based alloys, silicon-based alloys, germanium-based alloys, aluminum-based alloys, antimony-based alloys, magnesium-based alloys, and other alloys, also no commercial products.
5) Nanoscale
Carbon nanotubes, nano-alloy materials.
6) Nano-oxide
At present, according to the new market development trend of lithium battery new energy industry in 2009, many companies have started to use nano-titanium oxide and nano silicon oxide added to the former traditional graphite, tin oxide, nanocarbon tube inside, greatly improve the charge and discharge capacity of lithium batteries and charge and discharge times.
