Introduction
This video explains key parameters of batteries: capacity, cycle life, energy density, specific energy, and C-rate. The purpose is to provide a basic understanding of these important characteristics for consumers of electronic devices.
Key Takeaways
Battery Capacity: The total amount of electricity a battery generates, determined by the mass of active material. Measured in Ampere-hours.
Cycle Life: The number of full charge/discharge cycles a battery endures before its capacity drops below 80% (generally considered end-of-life).
Energy Density: The amount of energy a battery contains relative to its size (volumetric energy density), measured in Watt-hours per liter.
Specific Energy: The amount of energy a battery contains relative to its weight (gravimetric energy density), measured in Watt-hours per kilogram. Higher energy density leads to smaller, lighter batteries.
C-Rate: Measures the speed of charging or discharging. A 1C rate means a full charge/discharge in one hour; higher C-rates indicate faster charging (e.g., 3C is three times faster).
