Week 1 Understanding Different Battery Chemistry

The lithium combines with metal oxide to form a lithium metal oxide and release energy. The lithium polymer battery uses lithium metal for the negative electrode and a transition metal intercalation oxide for the positive. When the battery is recharged the chemical reaction is reversed. The lithium is thus both a reactant and the mobile ion that moves through the electrolyte. The overall chemical reaction is:

• Lithium batteries are primary batteries that have metallic lithium as an anod. These types of batteries are also referred to as lithium-metal batteries.
• A lithium-titanate battery is a modified lithium-ion battery that uses Lithium-titanate nanocrystals instead of carbon on the surface of its anod.
• lithium ion manganese oxide battery(LMO) is a lithium ion cell that uses manganese dioxide, MnO as the cathod material.
• The lithium iron phosphate battery(LiFePO4 battery) or LFP battery (lithium ferrophosphate), is a type of lithium ion battery using LIFePO4 as the cathod material, and a graphitic carbon electrode with a metallic backing as the anode.
• The overall chemical reaction is: XLi+ MyOz ------LixMyOZ
• The electrolyte is either a liquid organic solution or a solid polymer. Electrical energy is obtained from the combination of the lithium carbon and the lithium metal oxide to form carbon and lithium metal oxide.
• The overall chemical reaction for the battery is:C6Lix + MyOz------- 6C+ LixMyO
