Chemistry and Components of Lithium Batteries

Lithium Battery Chemistry

Lithium batteries are based on the principle of electrochemical reactions between lithium-based electrodes and electrolytes. The most common types of lithium batteries are lithium-ion (Li-ion), lithium-polymer (Li-Po), and lithium-iron-phosphate (LiFePO4).

Components of a Lithium Battery

A typical lithium battery consists of the following components:

• Cathode: A positive electrode made of lithium-containing materials, such as lithium cobalt oxide (LiCoO2) or lithium nickel manganese cobalt oxide (NMC).
• Anode: A negative electrode made of carbon or graphite.
• Separator: A thin, porous material that separates the cathode and anode, preventing electrical short circuits.
• Electrolyte: A liquid or gel-like substance that conducts lithium ions between the electrodes.
• Current collectors: Metal foils or sheets that collect electrical current from the electrodes.
• Battery pack: Multiple lithium cells connected together to increase voltage and capacity.
