It is used to dry materials, such as food crops, cash crops, leather fuel (energy) many, such as solar, coal, straw, fuelwood, methane. However, the most clean, most economical to the number of solar energy has. The general method of solar drying of crops is relatively simple, it is natural sunlight. This solar drying technology in a long time, still occupy an important position. The disadvantage is that a long drying cycle, drying yard Read More…

01) defragmenting the hard disk “failure”

Recently the use of Windows native defrag functions encounter a strange question, select the. Set by “analysis” button, it says “need to Defrag the hard disk” and then click the “order”, too – after the prompt “order complete”, but distribution of data on the hard disk does not happen any | any change (still very messy ), I cup defrag simply no doubt play a role, how is this going on, hard drive broken? Are there any other way to solve 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…

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…

Polymer lithium-ion batteries in 1999, Japan took the lead in industrialization. China has also started the production, such as Xiamen Baolong Battery Co., Ltd. and Guangdong Huizhou TCL King to Battery Co., Ltd. has begun production. At present the company for the production of polymer lithium-ion battery is not exactly the same route, and these companies are not to be too much of these technologies open. The following Read More…

Currently used in rechargeable lithium-ion battery There are two ways: constant current charging and constant voltage charging, of course, carried out between the two can cross. The former is mainly used for laboratory research, which is less used. In the constant current charging process, the threshold voltage increases quickly, the general capacity increases linearly with time, the internal resistance also increases. Read More…
