Over the last two articles, we covered how and why cycles have limited battery recharging. We discussed in detail the effect of a charge-discharge cycle – a chemical change in a battery system which results in degradation and loss. But there's something in my last article that deserves special attention. This factor is behind the degradation of the battery. And 'the reason why the battery is never a single course can always go higher e. The fact is that all batteriesdegrade and lose power because of a reduction of the active material of the battery.

We know that a battery of a device that converts chemical energy into electrical energy. To convert the chemical energy into electrical energy, there is a chain of events that can occur before the creation of electricity. The chain of events were discussed in detail in previous articles that you can access my blog, but what is the key to the creation of electrical energy in batteries is thatElectricity is of two chemicals that are produced in a solution. After discharge of the battery to recharge a battery charger. The charging process goes intercalation: the combination of a molecule (or molecule group) between two other molecules (or groups). Intercalation is the process of ion electric current led to compounds of lithium solid. Lithium is one of the chemical components used to produce electricity in batteries. Lithium compounds of the narrow spaces betweencrystallized planes for small ions, suitable for a force of electricity. Loads of lithium radiation levels of the network to the point where they are forced into a flow of current. Intercalation fills in fact, the lithium, but the result of ionization is the ultimate degradation of the property lithium-responsive. You might say, if you will be able to use it, lose it!

Why is the use of lithium in the chemical sector is to create electricity in batteries? There are a number of good reasons – let's glancefew!

Lithium is one of the alkali metals group (other metals) are sodium, potassium, rubidium, cesium and francium. Lithium is highly reactiveMetal. Li) has a single electron in the outer shell (two electrons in the inner shell, making it chemically lose "ready", that an electron in ionic bonding with other elements. Lithium batteries will be used as material of the anode () because of its high potential electrochemical. electrochemical potential is the sum of the chemical potential and the electric potential. The higher the electrochemical potential yields better electrical current. In some cells, based on battery –electrochemical potential is five times greater than an equivalent lead-acid cell-average and three times higher than alkaline batteries. Another advantage is that lithium is basic is that they are soft and flexible, based on the fixed configuration in small cell designs possible (PDAs. laptops, cameras, etc. ..).

Lithium, even with all its good chemical properties, but eventually responded to the point where the electrochemical potential of a tax return is not enoughcreate electricity to power a device.
