Battery Information 1
Battery is a cup, tank or other container or composite container part of the space that filled with electrolyte solution and the metal electrode to produce electric current . As technology advances, the battery generally refers to a small unit to produce electricity. Such as solar cells. Main performance parameters of the battery electromotive force, capacity, specific energy and resistance.
Main performance parameters of the battery includes electromotive force, capacity, specific energy and resistance. Electromotive force is equal to units of positive charge from negative to move through the cathode inside the battery when the battery of non-electrostatic (chemical force) done by power. Electromotive force depends on the chemical properties of electrode materials, has no relationship with battery size. The total output of the battery is the capacity of it, and ampere-hours is its unit. In the battery reaction, 1 kg-reactive substances produced by the battery power is called the theory of specific energy. Cells were actually higher than the energy smaller than the theoretical specific energy. Because the batteries are not all reactants reaction according to the battery while the battery internal resistance caused by electromotive force must fall, so often the battery than the energy, high-called high-energy batteries. The larger the size of the battery, the smaller the resistance.
Battery energy storage is limited, the battery can charge the total amount of output is called its capacity, usually treated as unit in ampere-hours, it is also one of the battery performance parameters. The capacity of the battery related to the number and electrode material, namely the size of the electrode.
Practical chemical batteries can be divided into two basic types: galvanic cell and batteries. After made, the galvanic cell can generate current, but it cann’t be recharged, will be abandoned once the discharge is completed. Battery also known as secondary batteries before use should be charged, charge to use after discharge, discharge can also be charged after the re-use. Battery charging, the energy converted into chemical energy; discharge, chemical energy into electricity.
