lithium battery: essential equipment of digital products

Li-ion battery is a class of lithium metal or lithium alloy anode material, the use of non-aqueous electrolyte solution batteries. First appeared in lithium battery(lenovo battery) using the following reaction: Li + MnO2 = LiMnO2, the reaction of oxidation-reduction reaction, discharge. As the chemical properties of lithium metal is very lively, making lithium metal processing, preservation, use and environmental requirements are very high, so applications are not widespread.

Later, Japan’s Sony Corporation has come to carbon materials for the anode to cathode containing lithium compounds for lithium batteries, charging and discharging process, there is no lithium metal, and only lithium-ion, which is Lithium-ion batteries(lenovo n100 battery,thikpad x200 battery). When charging the battery when the battery on the positive lithium ion generation, resulting lithium-ion movement through the electrolyte to the cathode. As the carbon anode layered structure, it has a lot of micro, to lithium-ion on the anode embedded in porous carbon layer, the embedded lithium-ion the more the higher the charge capacity. Similarly, when the battery discharge (ie, the process we use the battery), embedded in the carbon cathode layer of lithium-ion extrusion, but also movement back to positive. Back to the cathode of lithium-ion the more the higher discharge capacity. We usually say that the battery capacity is the discharge capacity. In the Li-ion charge-discharge process, lithium-ion transition from the positive → negative → positive moves in space. Li-ion Batteries is like a rocking chair, rocking chair at both ends of the lenovo n100 battery poles, while the lithium-ion rocking back and forth as players do run. Therefore, Li-ion Batteries also known as rocking chair batteries.

In order to develop a performance superior varieties, people of various materials were studied. Thereby creating an unprecedented product. For example, lithium sulfur dioxide batteries and lithium-thionyl chloride batteries is very characteristic. Their is also a positive active material and electrolyte solvent. This structure is only in the non-aqueous electrochemical system, to appear. Therefore, the lithium thinkpad x200 battery research, but also contributed to the electrochemical theory of non-aqueous system development. In addition to using a variety of non-aqueous solvent, the polymer film was also carried out cell research.

Lithium-ion batteries for its unique performance advantages in portable appliances such as laptop computers, cameras, mobile communications are universally applied. At present the development of large-capacity lithium-ion batteries in electric vehicle to start a trial, expected to become the 21st century, the power of electric vehicles, one of the main driving force, and a satellite, aerospace and energy storage aspects applied. With the energy shortage and global environmental pressures. Lithium is now widely used in electric vehicle industry, especially iron phosphate lithium lenovo n100 battery materials, the appearance, they also promote the development of the lithium battery industry and application.

With digital products such as mobile phones, notebook computers and other products widely used lithium-ion batteries with excellent performance in these products are widely used, and in recent years gradually to other areas of the development of product applications . In 1999, companies such as Shenzhen BYD began commercial production of lithium-ion batteries. Traditionally, it is the lithium-ion battery, also known as Li-ion batteries, lithium-ion battery has now become the mainstream.
