Just like standard lead acid batteries, Lithium batteries consist of positive plates (cathod es) and negative plates (anodes) as well as insulating separators to avoid short circuits between the positive and negative plates, and finally electrolyte, which is the conductive liquid although unlike flooded lead acid batteries, there is no free liquid in LiFePO4 batteries. A lithium battery differs in the materials used for the above mentioned components, especially the cathode and also the process undertaken during charge and re-charge. A lead acid battery undertakes chemical reactions, which change their components. Lithium just transfers ions during the charge and discharge process leaving everything else the same.
