Cadmium – nickel battery charging process, with the charge to the battery voltage increases, when the voltage exceeds 1.55V, the electrolyte water electrolysis, precipitation of gas, reduce the charging efficiency, charging efficiency of 85 normal % of. Cadmium – nickel battery charge voltage and charging mechanisms. The greater the charge current, charge voltage higher charge temperature is Read More…

For the secondary battery (batteries, rechargeable batteries) is concerned, life cycle or life cycle is also a measure of battery performance of an important parameter. After a secondary battery charge and discharge, as a cycle, or call a cycle.

Certain discharge conditions, the battery capacity dropped to a specified value before the number of cycles the battery can 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, gallium arsenide solar cells and so on. Read More…

Solar photovoltaic solar cells is the basis and core of a photovoltaic effect using the optical device can change the energy, also known as photovoltaic devices. With the appropriate wavelength of light shines on some of the material, its absorption of light energy generated at both ends after the electromotive force, known as the photovoltaic effect. This phenomenon in the liquid and solid Read More…

The battery used in tandem or in series constitute a single cell battery use, according to Faraday’s law, a single unit of time per battery and each electrode is equal to the electricity passed, if the capacity difference between the individual cells, or a single cell in the electrode capacity and other single cell capacity of different electrodes, Read More…

Battery into the battery life on hold life (storage life>, a battery life, rechargeable battery cycle life.

Battery storage life refer to standard rules Ding or human cells under the conditions of charge storage time, in general, until after the end of the battery storage, battery capacity requirements remain some value, 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…
