The development of lithium batteries and the proliferation of one product in the future are carried out on the basis of another product, and lithium batteries are no exception. Batteries have been used as storage devices for electrical energy for 200 years, from the original non-rechargeable batteries (such as zinc-manganese batteries) to rechargeable batteries (such as lead-acid batteries, nickel-metal hydride batteries, nickel-cadmium batteries) to the most recent lithium batteries. Lithium battery technology has been studied since the 1960s and was commercialized by Sony Corporation in Japan in 1992. It has been introduced to the market in several stages. In addition to increasing the demand for the original market and new products, it was also added by replacing products with similar functions: from 1992 to 1996, this was the trial processing stage and the market guidance stage, and there was no large-scale use. Since 1996, it has entered the mass production stage. Lithium batteries have gradually replaced nickel-nickel-cadmium batteries in the use of small battery products due to their obvious advantages in energy density. From 1996 to 2000, the early lithium battery was 18650, which was first used in notebook computers and some handheld communication devices, and gradually replaced Ni-MH/Ni-Cd storage. From 2000 to 2003, 3C digital devices such as mobile phones began to fully replace Ni-MH/Ni-Cd batteries. Around 1998, with the mass production of square-shell and soft-packed lithium batteries, as well as the demand for lightweight and compact digital communication equipment, lithium batteries were basically unified in the 3C digital category. During this period, BYD entered the supply chain of mainstream mobile phone manufacturers, began to expand its parts and OEM business, and its sales began to double. ATL was also during this period when a big ship named Apple set sail, braving the wind and waves. From 2003 to 2007, with the gradual reduction of the cost of lithium batteries, nickel-metal hydride batteries were replaced in small home appliances, tools and toy stores. During this period, 18650 was developed as a standard product used in the above categories. From 2007 to 2011, with people's interest in smart phones, soft-pack polymer lithium batteries began to dominate the use of mobile phones and peripheral devices in shopping malls. At the same time, some companies are exploring the use of lithium batteries in electric vehicles. Since 2011, lithium batteries have been vigorously developed in three directions: electric vehicles began to use electric vehicles in large quantities, and Tesla (Tesla) launched modelS in 2012. 2. Starting from the evolutionary era of information use, Internet information, as well as the fully developed skills of integrated circuits, and product Ru0026D and capital circulation are getting lower and lower, the cycle is getting faster and faster, entering the product, pitifully bursting out a variety of new Where electronic products continue to increase the market scale of lithium batteries, such as Bluetooth, smart home sauce, drones, e-cigarettes, personal care products, etc. in industrial energy storage, household energy storage, two-wheeled vehicles, tool carts, UPS, etc. The field replaces lead-acid batteries. Future market trends Since 1992, the global lithium battery market has reached 200 billion yuan, with an average annual compound growth rate of more than 20%. This is the result of the long-term rapid rise of the industry. It is foreseeable that the next ten years will continue to maintain a steady upward trend. The rise in the following three aspects is relatively obvious: 1. Electric vehicles are gradually replacing gasoline vehicles, and lithium batteries will be an important power component in the next ten years. A Although the energy density of the current battery is only 200WH/Kg, which is much lower than the energy density of 12000Wh/Kg gasoline, the motor power exceeds 90%, which is much higher than the energy density of the internal combustion engine, which greatly saves resource consumption. With the improvement of the technological level and the increase of battery energy density, the bottleneck problem of the range of electric vehicles can be solved. B. Environmental factors, electric drives have almost no carbon emissions. C cost, the motor transmission structure is simple, if the battery cost is reduced, the cost of electric vehicles is much lower than that of fuel vehicles. D-electric drive has fast response, low noise, and more fun to operate. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
