Lithium-ion batteries, the overall market development present situation analysis

Source: 2020 - 04 - 06 12:21 hits: lithium battery is how the birth of the lithium-ion battery invented in 1990, the first lithium battery from the great inventor Thomas Edison, its excellent performance has been rapid development, with the development of science and technology, lithium battery has become the mainstream, now we are familiar with mobile phones, laptops, small cameras, and so on, are widely used in the society. Lithium ion is the most basic electrochemical and lithium in the electrochemical cell. Compared with other batteries, lithium-ion batteries have many areas, has high working voltage, than can big, long cycle life, low self-discharge rate, no memory effect, etc. Lithium battery can remember it by changing energy can carry electricity. It is a memory cell. Can use the original charger, each half can't picture, pull, or the battery will reduce the memory cell, don't wait for energy costs, don't use a mobile phone can be inserted into the charger, so you can keep the battery the maximum amount of memory, don't worry about it will automatically power off. Lithium excellent performance, small size, weight and volume of the same lithium battery capacity can be very big, light weight, high power density, its disadvantage is lithium ion battery are very delicate, charging control voltage requirements is very high, its demands far more than our daily commonly used lead-acid, nickel-metal hydride and nickel cadmium metal hydride rechargeable battery. Under the condition of normal charging and discharging. Many chargers on the market, in particular, common charging voltage too much scattered, insufficient charging, or charge occurred. The correct use of the charger, the use of lithium battery charger for the influence of the environmental safety of the equipment. At present, the sustainable development of the lithium battery has a good prospect. Solar energy can be used to store excess electricity, for instance, when there is no power supply, lithium battery can be used to provide power. Lithium ion battery of the overall market development status in the past two years, the demand for lithium ion battery has been growing fast. According to the true lithium research statistics, in 2011 the global market demand of 26 lithium-ion batteries. 63. 580000 KWH, 2013 to 5150. 40000 kilowatt hours, an average annual growth rate of 39. 05%. Classification from the point of view of the market, although in the consumer electronic products, the demand for lithium ion batteries is still strong, it can be considered to be the demand for lithium ion battery of high growth was dominated by cars by electric cars, electric bicycles, and industrial and energy storage areas. Vibration force study mobile phones, tablet PC, laptop computers, digital cameras and provide these products with the battery life of mobile power supply and other consumer electronics products are classified into the consumer electronics market, including electric bicycles, electric motorcycle and electric tricycle motors, low-speed electric cars and xE V ( Hepatitis e virus, P hev, EV) Is listed as electrification market, electric tools, industrial equipment, mobile base station power supply, power grid energy storage, energy storage and other U P S power market is divided into industrial and energy storage. In recent years, the consumption structure of lithium ion battery market in the world is: the great changes are the focus shifting from consumer electronics to electrification, industry and energy storage market. In 2011, the consumer electronics market lithium ion battery product usage is 21325700 kw/h, accounts for over 80% of the total market. At the same time, electrification and industrial energy storage market demand for lithium ion batteries are 2 respectively. In 9254, 400 kWh and 2. 384700 kWh, accounting for less than 20% of total demand. In 2012, electrification market demand for lithium ion batteries, 597. 070000 KWH, double year-on-year growth, market share in 2011 from 10. 98% to 15. 48%. In 2013, the demand of 1144. 340000 KWH, year-on-year growth of nearly doubled, to further improve market share to 22. 22%. In 2012, industry and energy storage market demand for lithium ion batteries for 467. 360000 KWH, year-on-year growth of nearly doubled. Market share from 8 in 2011. 95% to 12. 25%. In 2013, the demand of 773. 190000 KWH, 65 year-on-year growth. 44%, further market share growth to 15. 01%. The rapid growth of the lithium-ion battery market is mainly due to the rapid fall of lithium ion battery price, stimulate the purchase desire of consumers. To this point in the electric car market is obvious. Lithium from real research, according to data from each fell by 10%
