The development of lithium ion battery and the future

Source: 2020 - 03 - 29 then hits: lithium-ion battery development and future of the spread of a product is in another product, on the basis of the lithium ion battery is no exception. Battery as energy storage device has been 200 years of history, from the initial non-rechargeable batteries ( Such as zinc manganese battery) The rechargeable battery ( Such as lead-acid battery, nickel metal hydride batteries, nickel cadmium battery) To the more recent lithium ion batteries. Lithium ion battery technology since the 1960 s, studied and SONY commercialized in Japan in 1992. It has several different stages to the market. In addition to increasing the original market and the demand of new products, also by replacing the similar function products to increase: from 1992 to 1996, this is the trial production and market guidance phase, not a lot of use. Since 1996, has entered the stage of mass production. The energy density of the lithium ion batteries due to the obvious advantages, in the use of small battery gradually replaced the nickel Nickel - Cadmium battery. From 1996 to 2000, the early lithium ion batteries is mainly 18650, the earliest used for handheld communication devices, notebook computer and some gradually replaced the ni-mh/ni-cd storage. From 2000 to 2003, mobile phone and other 3 c digital equipment to fully replace ni-mh/ni-cd battery. Around 1998, as the side shell, soft packing lithium ion battery production, and the requirements of lightweight, compact digital communication equipment, lithium ion battery basic unity in 3 c digital category. In the meantime, byd to enter the mainstream mobile manufacturers supply chain, expanding parts and OEM business, sales began to double. ATL is also during this period, a ship called 'apple' ship began to set sail, braving the. From 2003 to 2007, with the lithium ion battery costs reduce gradually, nickel metal hydride batteries be replaced in the small home appliance, tools, and toy shop, in the meantime, 18650 has been developed into the above categories used in the standard products. From 2007 to 2011, with interest in smart phones, soft package of polymer lithium ion battery began to dominate the market in the use of mobile phone and peripheral equipment. At the same time, some companies are exploring using lithium ion batteries in electric cars. Since 2011, the lithium ion battery is developing in the three directions: electric cars began extensive use of electric cars, tesla ( Tesla) In 2012, introduced the model S. 2, start from the message using Internet information evolution s, as well as the skills of full development of integrated circuits, and product research and development and the circulation of capital is more and more low, cycle faster and faster, from entering the product, the outbreak of the poor all kinds of new electronic products, constantly improve the market size of lithium ion battery, such as bluetooth, intelligent household sauce, unmanned aircraft, electronic cigarettes, such as personal care products in the industrial energy storage, home storage, two rounds of car, van, UPS and other fields instead of lead-acid batteries. The future market trend since 1992, global lithium battery market scale has reached 200 billion yuan, an average annual compound growth rate of more than 20%, this is the result of the rapid growth of industry for a long time. Predictably, the next 10 years will continue to adhere to the trend of steady growth, the growth of the following three aspects are obvious: 1. Electric cars are gradually replace gasoline cars, lithium ion batteries will be the main dynamic element in the next decade. Although there is A battery energy density of only 200 wh/Kg, far below the 12000 wh/Kg energy density of gasoline, but the motor power more than 90%, far higher than that of more than 30% of the energy density of the internal combustion engine, greatly save the resource consumption. With the improvement of technical level and the improvement of the battery energy density, the electric car range of bottleneck problem can be solved. B environmental factors, electric drive almost no carbon emissions. C costs, motor drive structure is simple, if the battery cost reduction, the electric car was much lower than the cost of fuel cars. D - Electric drive fast response, low noise, manipulation of the fun.
