Bottleneck in computer ¬ebook batteries

Bottleneck in computer & notebook batteries


With the progress of the notebook battery computer technology,dell laptop battery From a mobile office concept has already become a reality. In order to meet the needs of mobile and mainstream manufacturers are introducing more powerful, more stable system of ultra-thin notebooks. Used for this ultra-thin battery, RC107 Battery
Latitude D620 Battery, 312-0386 Battery, PC764 Battery,but because of the lack of electricity has become a new bottleneck in mobile office. And, in addition to persistent power, the battery is very expensive prices, and a piece of notebook batteries accounted for 10% of the overall price -15%, then an ultra-thin laptop battery should have the characteristics of what it mobile office to meet the demand? From the practical point of view we may wish to analyze the design of laptop battery standard.


Industry experts believe that time is of the battery. Ultra-thin notebook computers because of the thin body makes room for the installation of the toshiba battery becomes more limited, and the battery means to reduce the volume of the power supply even shorter time, not every ultra-thin notebook computers can be up to standard the battery life. At present, a common ultra-thin notebook battery time between 2-3 hours, a good brand can be achieved for about four hours, there are higher, such as NECS820 will be able to provide electricity five hours time, and if equipped with backup battery, the life of up to 11.8 hours. Moreover, the computer which is designed to extend the battery very thin flat-shaped, and its size and the fuselage in line with the expansion of the bottom of the chassis battery integrated with the fuselage,PC764 Battery, and fully maintained the smooth state of the fuselage.


However, even the best batteries, its power can not be unlimited, and the total time spent, and a charge can be completed in the shortest possible time that the battery may be the user’s mobile office to offer as much convenience and efficiency. RC107 Battery
Latitude D620 Battery, 312-0386 Battery, PC764 Battery,Which most users are often easy to forget where the most ordinary laptop charging time is 3-7 hours, with better products to be completed in 2.4 hours recharge.


In addition, some regular users to minimize the use of a variety of components to achieve extended battery life of purpose, for example, do not use CD-ROM, hard disk read as little as possible to reduce the screen brightness or simply dormant and so on. These approaches can indeed maintain the battery a little more time, but “a temporary solution”, select the design of a battery with excellent products, in order to fully enjoy the convenience of mobile office with the fun.


Hybrid battery concern


November 27, 2004 ~ 29, held in Kyoto, “the 45th Battery Symposium” on the hybrid’s rechargeable batteries for concern. During the meeting,312-0386 Battery, held the last day of the “lithium-ion battery (large-scale security review)” At the meeting of many people who can not find seats, not even squeeze into a lot of people standing outside the venue of the lecture. Required on both hybrid high-power density, high energy density and high-wide features such as the practical use rechargeable batteries, Hitachi Vehicle Energy (Hitachi Vehicle Energy), Matsushita Battery Industrial, Yuasa (GS Yuasa) companies such as published the results of the battery trial.


Among them, the Hitachi Hitachi Vehicle Energy and by the success of joint development is the appearance of the size of 108mm × 34mm × 117mm, weighs approximately 770g at right angles to the flat toshiba tecra a3 battery, toshiba tecra a4 battery. Average working voltage of +3.6 V,RC107 Battery
Latitude D620 Battery, 312-0386 Battery, PC764 Battery, the weight ratio of energy density 70Wh/kg. To ensure that the discharge capacity can be up to 20C discharge at 0.5C discharge, Latitude D620 Battery,80%, while electricity can discharge up to 20C to ensure that the 0.5C discharge at the time of above 75%. C indicated that the discharge rate, rechargeable 1 hour discharge at 1C, charging for three hours discharge 20C.


The use of non-crystalline carbon anode, cathode to Mn (manganese)-based materials using a special element of replacement materials. Products has been developed and compared to the particles to improve the cathode structure, the use of thin electrodes, and to reduce the resistance of structural components of a great martial arts aspects. As for facing the future issues of the 2:00 session, that is the end of battery life can also be low-temperature work, as well as in maintaining the power density at the same time increase the energy density.


Tube-type solid oxide fuel cell successfully developed


A few days ago, the Chinese Academy of Sciences Dalian Huawusuo the use of low-cost preparation of inorganic membrane technology successfully prepared tube solid oxide fuel cell, single-tube 1.0V battery open circuit potential in more than 800 ℃, 0.7V the output power up to 25W above.RC107 Battery The tube-type cell research breakthrough for the development of solid oxide fuel cell distributed power plant and power station to provide a key focus on technology.


Solid oxide fuel cell membrane electrode configuration of the main plate and tube. Tube-type battery has good stability, ease of amplification module, suitable for the establishment of power stations, but the electrolyte membrane electrode electrochemical vapor deposition in general (EVD) technology to prepare, cost expensive. Therefore, the development of low-cost tube-type membrane electrode manufacturing technology, the development of solid oxide fuel cell power plant is crucial. Direction in the Chinese Academy of Sciences and Ministry of Science and Technology project, supported by cast Dalian Huawusuo in solid oxide fuel cell membrane electrode forming the base, electrolyte and cathode coating film coating technologies,RC107 Battery
Latitude D620 Battery, 312-0386 Battery, PC764 Battery, such as the preparation made significant progress, the success of the preparation  8mm × 500mm tube film electrode to solve the single-tube flow cell and sealed set of technical issues, the battery is good for repetition priming, high reliability. In the tube during the preparation of membrane electrode, the use of low-cost preparation of inorganic membrane technology, abandoning the high cost of chemical vapor deposition CVD correspondence and EVD technology, a significant reduction in the tube of Preparation of the cost of batteries for the future type of toshiba tecra a5 battery, toshiba tecra a6 battery industry technology development and solid oxide fuel cell has laid a good practical use of the technology base.
