Application prospect of lithium battery

Application

With the development of microelectronics technology in the 20th century, increasing miniaturization of equipment, puts forward high demands on the power supply.The lithium battery then entered the practical stage of mass.

The earliest available is lithium battery, used in cardiac pacemaker.Due to the lithium battery self-discharge rate is extremely low, discharge voltage is very gentle.That makes it possible to pacemaker implantation in the human body use for a long time.

Lithium manganese batteries tend to have higher than the nominal voltage of 3.0 v, is more suitable for integrated circuit power, widely used in computers, calculators and watches.

Lithium ion batteries a large number of applications in mobile phones, laptops, electric tools, electric car, street lamp standby power, navigation lights, small household electrical appliances, can be said to be the largest application group.

prospects

In order to develop more excellent performance of varieties, people of various materials were studied.To create an unprecedented products.For example, lithium sulfur dioxide battery and lithium thionyl chloride battery is very characteristic.Their positive active material and electrolyte solvent.This structure only in non-aqueous solution of electrochemical system.Therefore, the research of lithium-ion batteries, also promoted the development of non-aqueous system electrochemical theory.In addition to use a variety of nonaqueous solvents, people also has carried on the research of polymer film battery.

Lithium-ion batteries are widely used in hydraulic, energy storage power system such as fire, wind and solar power stations, posts and telecommunications communication uninterruptible power supply, and power tools, electric bicycles, electric motorcycles, electric cars, military equipment,special and other fields.

Lithium ion battery with its unique performance advantages in portable electronics such as laptops, cameras, widely used in mobile communications.Development the large capacity of lithium ion battery has started trial in electric cars, is expected to be one of the main power source in the 21st century, the electric car, and will be in the aspect ofspecial,special and energy storage applications.As energy shortage and the environmental pressure of the world.Li-ion battery is widely used in electric car industry, particularly the emergence of lithium iron phosphate batteries, has promoted the development and application of lithium battery industry.

The planning stage is expected to change the world pattern of lithium battery

On April 18, the state council discuss passed "energy saving and new energy vehicles industry development planning (2012 ~ 2020)" (hereinafter referred to as "planning"), has been clear about the pure electric drive for auto industry transformation of the main strategic orientation, popularization of plug-in hybrid vehicles, and put forward the pure electric and hybrid cars in 2015, the cumulative volume has reached 500000, the goal of more than 5 million vehicles by 2020.

The policy of "planning", cause huge attention in it.Many experts believe that the move will promote the industry into a new round of development, in addition, also in virtually as the core component of energy saving and new energy vehiclesPower batteryDraw an outline of the a huge market.

According to data shows, 2008 global lithium ion battery production is 2.78 billion, about $7.1 billion, industry in the lithium ion battery production growth in 2011 to 4.64 billion, a $15.3 billion industry.In the study of lithium ion battery industry in China in 2012, according to China is the world outside of Japan's largest producer of lithium ion battery and main consumer, is worth 39.74 billion yuan.The "planning" a powerful propellant, is expected to change the pattern of current world lithium battery industry.

production

China is the world's largest lithium battery production base, the second largest producer and exporter, lithium-ion batteries, lithium batteries has accounted for 40% of global market share.In 2011, China has reached 2.966 billion, lithium battery production rose 10.88% year-on-year, domestic exports of $438300, lithium-ion batteries to achieve trade deficit of $335.0077 million.

Along with the mobile phones, notebook computers, digital cameras, electric cars, electric tools, and new energy vehicles industry fast development, the demand for lithium battery will be growing, at the same time, due to the lithium battery manufacturers in technical innovation, people demand for lithium batteries of the growth will continue, lithium battery production of 2012, China's growth is expected to stay above 10%, by 2015 China's lithium battery industry output value will reach 353 billion yuan.
