Lithium batteries will be essential equipment for digital products

February 2nd, 2010

Li-ion battery for Fujifilm np-120 is a class of lithium metal or lithium alloy anode material, the use of non-aqueous electrolyte solution batteries. First appeared in lithium 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 Canon nb-71 batteries, charging and discharging process, there is no lithium metal, and only lithium-ion, which is lithium-ion 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 Samsung sb-lsm160 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 battery Jvc bn-vf823 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 studied various materials . Thereby creating an unprecedented product. For example, lithium sulfur dioxide batteries for Jvc bn-vf808 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 akku 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 Dell inspiron 6400 battery are universally applied for its unique performance advantages in portable appliances ,such as laptop computers, cameras, mobile communications . 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 battery materials, the appearance, they also promote the development of the lithium Dell vostro 1500 battery industry and application.

As digital products widely are used such as mobile phones, notebook computers and other products , lithium-ion Canon nb-5l batteries with excellent performance are widely used in these products, and in recent years gradually to other areas of the development of product applications. Traditionally, it is the lithium-ion battery, also known as Li-ion batteries, lithium-ion battery has now become the mainstream.

Nickel-metal hydride batteries will become the focus of China policy support at the present stage

January 15th, 2010

In the new energy vehicle development strategy,countries and regions all over the world have been based on their assessment of different options, they are taking a different strategy to promote support for the relevant Canon NB-2LH battery technology research and development and . From the current situation as a whole, Japan and the United States and Europe focused primarily on lithium batteries and fuel cells, but as taking into account the resources and technology maturity, in the newly released policy,China emphasis on promotion of nickel-metal hydride batteries for Kodak klic-8000 .

Although Ni-MH battery is the commercialization mainstream , but the main indicators of laboratory data are lower than lithium batteries, and for the basic theory, there is no room to improve;despite of the lithium Dell precision m series battery superior performance , but safety still can not be guaranteed, and the relatively high costs also impede their business.

Experts predict that the new energy vehicles will be in the “Ni-MH – Lithium-Ion battery – fuel cell” industry-oriented development path. From the development trend and rate, and short-term performance can be realized only nickel-hydrogen Dell precision m90 series battery , since nickel-metal hydride battery technology is the most mature in the next three years, it will remain the mainstream of new energy vehicles, followed by nickel-metal hydride battery technology and lithium iron phosphate, hydrogen fuel are cell-third of the world, 5-year lithium batteries and will be gradually replaced by fuel cells.

Battery giant Panasonic and Sanyo also found that the lithium-ion Sony NP-FP70 battery can not replace nickel-hydrogen batteries in 2 ~ 3 years, , mainly due to cheaper nickel-hydrogen battery safety,it has reached large-scale production.

According to Japan’s Fuji economic analysis, the mainstream nickel-metal hydride batteries will be able to continue until 2011, but after 2011, Li-ion Kodak KLIC-8000battery will gradually erode the market share of the nickel-metal hydride batteries.

In our letter to the Department of Public June 25 that the “new energy automobile manufacturing companies and product access management rules” from China , the vehicle according to the new energy vehicles, systems and key assembly Nikon EN-EL3 battery technology maturity, degree of perfection of the national and industry standards, and industrial the degree of difference it will be divided into three different stages of technology maturity, and is given classified management.

Experts believe that the reason why China now focus from the development of lithium batteries into nickel-metal hydride batteries, the main reason is that nickel-metal hydridePanasonic CGA-DU21 battery technology is more mature than the lithium batteries, more abundant mineral resources, the future of new energy vehicles will enable greater access to the commercial phase.
