Currently, countries in the world to promote the third generation mobile communication systems, while industrial, research focus has gradually Beyond 3G third generation of people after the> or the new generation of 4G mobile communication technology, wireless broadband communications technology, the research group aims to make wireless communications spectrum efficiency, capacity and rate of ten times or even a hundred times, which means that from now MBPS increased to the order of Gbps, which requires looking at the concepts and technology Read More…

You must often hear people say: this computer unstable, often crashes! Stability and instability of a computer, motherboard significant, this and a person’s body is not good, the cold is often the same reason. When you open the shell of the host computer, you will see a board studded with a variety of small circuit board, this piece of board is the motherboard. It is not only responsible for all data communication within the computer, Read More…

Battery designed to meet the power requirements of appliances carried out. On the one hand to meet the electrical apparatus to provide the best performance of the power supply, the other for the battery manufacturers to create the maximum profit. This requires that the battery design products with the lowest Read More…

Faraday’s law is the law of one of the important electrochemical science. Theory suggests the electrolysis of electricity through the electrode and the quality of the relationship between the reactants, and temperature, voltage, electrolyte concentration and solvent nature, independent of such factors as electrode materials. But Read More…

1, according to the different structure can be divided into the following categories.

(1) homojunction solar cell from the same material composition of one or more semiconductor pn junction solar cell. Such as silicon solar cells, GaAs solar cell and so on. Read More…

Discussed above, the molten salt electrolyte concentration cell and the molten salt electrolyte Jacobi – Daniel batteries. As you know, concentration cell of electromotive force depends on the solution of two electrodes inserted and two solution interface on the concentration of the electric potential jump, the lower the value of its Read More…

Lithium thermal battery 70 from the late 20th century, has been developed for more than 20 years, during which tackled many technical difficulties, has become mature. Since the thermal battery with outstanding quality performance, and soon formed a variety of products, get in the successful application of modern Read More…

Definition

Thermal battery is the battery itself, the heating system to a non-conducting solid state heating molten salt electrolyte showed ionic conductor and into the working state of a thermally activated reserve battery. Use of solid salt electrolyte thermal battery is the main feature, it apparently different from the use of aqueous electrolytes, organic electrolytes and solid electrolyte batteries. As the use of solid electrolyte salts, Read More…

As we all know, as an indispensable modern industrial raw material production of active metals such as lithium, sodium, potassium, calcium can not be separated molten salt electrolysis. 40 years of the 20th century developed the widely used high-tech sophisticated weapons to molten salt for thermal batteries are the battery electrolyte. These industrial sectors and the emergence and development of an urgent need for salt Read More…

In industry, social activities and daily life power energy is essential mainly to supply through the grid. So far most of the power grid operated by power companies, and in compliance with the premise of many of the provisions also provide stable power. However, competition principles and rules relaxed, fuel cells as electric power has been given a new space. Content of its rules relaxed: ① grid Read More…
