Chemical Composition:

• Anode: Lithium metal (Li)
• Cathode: Lithium manganese dioxide (LiMn2O4) or lithium vanadium pentoxide (LiV3O8)
• Electrolyte: Lithium hexafluorophosphate (LiPF6) dissolved in organic solvents

Key Characteristics:

• Nominal Voltage: 3.0 volts
• Wide Operating Temperature Range: -20°C to +60°C
• High Energy Density: Typically 200-300 Wh/kg
• Long Shelf Life: Over 10 years at room temperature
• Low Self-Discharge Rate: Less than 1% per year
