A typical LiPo cell has a nominal voltage of 3.7 volts and a capacity of 2000mAh. Next, calculate the total energy in watt-hours (Wh) using the formula: Energy (Wh) = Voltage (V) × Capacity (Ah). For a 2000mAh battery, convert to amp-hours: 2000mAh = 2Ah. Thus, Energy = 3.7V × 2Ah = 7.4Wh.
Then, determine the energy density for lithium polymer batteries. Energy density typically ranges from 150 to 200 Wh/kg. For computation, use an average value of 180 Wh/kg. The next step is to estimate the total weight of the battery. Divide the total energy by the energy density: Weight (kg) = Total Energy (Wh) / Energy Density (Wh/kg). For a 7.4Wh battery: Weight = 7.4Wh / 180Wh/kg = 0.0411kg or 41.1 grams.
Finally, calculate the lithium content. Lithium typically constitutes about 2% of the total weight of a LiPo battery. Multiply the weight by 0.02: Lithium Content (g) = Total Weight (g) × 0.02. For our example: Lithium Content = 41.1g × 0.02 = 0.822g.
Therefore, the lithium content in a 2000mAh LiPo battery is approximately 0.822 grams.
