What is discharge current in a lithium ion battery?
The discharge current is the amount of current drawn from the battery during use, measured in amperes (A). Li-ion cells can handle different discharge rates, but drawing a high current for extended periods can generate heat and reduce the battery’s lifespan.
How do I choose a lithium-ion battery?
Choose battery setups based on your performance and energy storage needs. The maximum current capacity of a lithium-ion battery is often referred to as its discharge rate, commonly expressed in “C” rating. A higher C rating indicates that the battery can discharge more current safely.
What does C mean in a lithium ion battery?
The maximum current capacity of a lithium-ion battery is often referred to as its discharge rate, commonly expressed in “C” rating. A higher C rating indicates that the battery can discharge more current safely. For example, a battery with a 10C rating can discharge ten times its capacity in amps.
How does lithium ion cell discharge work?
During discharge, lithium ions move from the anode back to the cathode. This movement generates an electric current, which powers your device. Proper discharge management is essential to avoid over-discharging, which can permanently harm the cell and diminish its capacity. 2. Li-Ion Cell Discharge Current
What temperature can a lithium ion cell charge and discharge?
Source : Hunan Huaxing New Energy Technology Co. Lithium-ion cells can charge between 0°C and 60°C and can discharge between -20°C and 60°C. A standard operating temperature of 25±2°C during charge and discharge allows for the performance of the cell as per its datasheet.
What is discharge voltage in a Li-ion battery?
The discharge voltage is the voltage level at which the cell operates while providing power. For li-ion cells, the typical voltage range during discharge is from 3.0 to 4.2 volts. It’s crucial to avoid letting the voltage drop below 3.0 volts, as over-discharging can lead to irreversible damage and significantly reduce the battery’s capacity.
