In the organic result of chemical cleaning bottle, chemical energy directly into electrical energy by an internal lithium bottle is spontaneous oxidation, reduction and other chemical reactions, such reactions are carried out on the two electrodes. Negative electrode active material by the more negative potential and stable in the electrolyte reducing agent, such as zinc, cadmium, lead and hydrogen active metal or the like hydrocarbons.
The positive electrode active material by the more positive potential in the electrolyte and stable oxidizing agent, such as manganese dioxide, lead dioxide, nickel oxide and other metal oxides, oxygen or air, halogens and their salts, oxyacids and salts thereof . The electrolyte is a material having good ion conductivity, such as an acid, base, salt solution, an organic or inorganic non-aqueous solution, molten salt or solid electrolyte. When the external circuit is disconnected, while the potential difference between the two poles (open circuit voltage), but there is no current, is stored in the chemical bottle cleaning electromechanical energy not converted into electric energy.
When the external circuit is closed, the potential difference at both electrodes of action i.e., a current flows through the external circuit. While inside the battery, since the transfer of free electrons, electric charge does not exist must be accompanied by oxidation of the bipolar active material and electrolyte interface or reduction reactions, and the mass transfer of reactants and reaction products in the electrolyte. Charge transfer in the electrolyte should be completed by the migration of ions. Thus, the internal electrical and mechanical cleaning of bottles of normal charge transfer and mass transfer process is a necessary condition to ensure normal output power. When charging, the direction of which conduct electricity and mass transfer inside the battery during the discharge exactly the opposite; electrode reaction must be reversible, in order to ensure the normal mass transfer in the reverse direction with current transfer process.
Is sweeping the thermodynamic relationship between the electromotive force of the reaction flask with electromechanical battery, lithium is calculated thermodynamic equations bottle energy conversion efficiency. In fact, when the current flow through the electrodes, the electrode potential should deviate from the thermodynamic equilibrium electrode potential, this phenomenon is called polarization. Current density (current per unit electrode area through), the more serious polarization.
Polarization is one of the important causes of organic cleaning bottles energy loss due to the electrolyte material constituting the organic cleaning bottles vary, a lithium ion polymer battery are also divided into two kinds of the battery and a liquid battery. Battery same polymer battery positive and negative electrodes with the liquid material, the working principle is similar to the battery, the electrolyte of which differ from each other. Lithium polymer bottle light, strong storage capacity, discharge performance and may cause a variety of shapes, and longer life. Bottle polymer electrolyte is a solid electrolyte, a liquid electrolyte battery with respect to the liquid, the polymer lithium can cause a variety of bottle shapes to improve the specific capacity of the battery.
