Lithium batteries use multiple cells. For example, a lithium-ion battery has 3 cells for 11.1 volts, 4 cells for 14.8 volts, or 10 cells for 37 volts. Cells can be arranged in series to increase voltage or in parallel to boost capacity measured in amp-hours (Ah). This setup meets different energy storage needs.
For full lithium utilisation, the cell capacity is 3860 mAh/g of lithium, simply calculated by Faraday’s laws. Thus, the actual rated capacity of the cell in mAh is determined by the weight of lithium in the cell.
Typical voltages vary by battery type, e.g., lithium-ion (3.6V or 3.7V per cell) and LiFePO4 (3.2V per cell). Energy per unit weight or volume, reflecting the battery's storage efficiency. Lithium-ion has high energy density compared to other chemistries, allowing more energy in a smaller, lighter package.
Lithium iron phosphate (LiFePO4) batteries have a typical energy density between 90 and 160 Wh/kg. They are known for their safety, long life, and ability to discharge deeply. What is the capacity of a lithium-ion battery in kWh? The capacity of larger lithium-ion batteries (such as those in electric vehicles) is often measured in kilowatt-hours.
Lithium-ion cells are rechargeable batteries that utilize lithium ions as the primary component in their electrochemical reactions. They are renowned for their high energy density, low self-discharge rate, and ability to be recharged multiple times without significant degradation. These cells are available in various shapes and sizes.
Lithium-ion batteries typically have an energy density of 150 to 250 watt-hours per kilogram, while lithium iron phosphate (LiFePO4) batteries are around 90-160 watt-hours per kilogram. How to check lithium battery capacity? Capacity can be tested using a multimeter or a battery analyzer that measures the discharge rate over time.
