Principles of the laptop batteries

In the chemical cell, chemical energy directly into electricity through the laptop batteries is carried out within the spontaneous oxidation, reduction and other chemical reactions the result of the reaction were carried out in two electrodes. The same time, the battery inside the electrolyte does not exist due to free electrons, charge transfer must be accompanied by two poles active material and Dell Studio 1535 battery electrolyte interface, the oxidation or reduction reactions, as well as reactants and reaction products of mass transfer. In fact, when the current flows through the electrodes, the electrode potential must deviate from the thermodynamic equilibrium of the electrode potential, a phenomenon known as polarization. from the electrode - electrolyte interface layer caused by charge transfer blocked the process of polarization is called activation polarization; from the electrode - electrolyte interface layer caused by slow mass transfer of polarization is called concentration polarization. Reduce the polarization method is to increase the electrode reaction area, reducing the current density, increasing reaction temperature and to improve the catalytic activity of the electrode surface.
