Principle of Batteries
Batteries must be differentiated into primary and secondary battery systems. While primary systems cannot be charged, the secondary systems, also known as accumulators can be recharged using
The lithium-ion battery is usually composed of several cells connected in series or in parallel. This allows both the nominal voltage and the capacity of the battery to be adjusted.
The connection is made by welding nickel strips. The layered structure of the cell is illustrated in the following graphic:
The two electrodes form the heart of the cell. Graphite is usually used for the negative electrode, while the positive electrode is made of a lithium metal oxide.
The cell is filles by a liquid ion-conductive electrolyte in which Li ions can move freely. The two solid electrodes are separated by a semi-permeable separator membrane, which is only permeable for Li ions.
The cathode is located on an aluminum foil, while the anode is placed on a copper foil. Two different materials are necessary here, as aluminum would react with Lithium ions at the anode
and copper would corrode on the cathode.
The chemical processes differ in the selected metal oxides. These are described below using the CoO2 cell:
Cathode - positive electrode
LiyCoO2 + x Li+ + x e- → Lix+y CoO2
This equation clearly shows that there is no chemical conversion of the materials used. Only Li ions migrate.
The same applies to other lithium metal oxides.
Charge and discharge
By applying a potential during the charging process, positively charged Li ions (Li+) are released from the lithium metal oxide and migrate to the graphite anode.
While discharging, the lithium ions migrate back to the metal oxide. Electrons can flow to the positive electrode via the external circuit during this process.
