Electric vehicles and energy storage systems use LiFePO4 batteries for their high energy density, lack of memory effect, low self-discharge, and long cycle life.
This article will explore the cycle life of LiFePO4 batteries.
The Cycle Life of LiFePO4 Battery
Cycle life refers to the number of cycles a battery reaches under certain discharge conditions when it works to a certain capacity. LiFePO4 batteries have a specified capacity of 80%. This “80%” is closely related to the battery’s design. It is closely related to the negative electrode’s excess capacity factor.
What Affects The Cycle Life of LiFePO4 Battery?
A battery’s charge and discharge cycles are called cycles. The number of cycles the battery reaches under certain discharge conditions when it works to a certain capacity is called cycle life. LiFePO4 batteries are specified as having a capacity of 80%. This 80% refers to the battery’s design and to the negative electrode’s excess capacity factor. It is closely related to the battery’s design.
Batteries’ cycle life decreases as they age and degrade. LiFePO4 batteries contain a variety of components, including active and negative materials, conductive agents, current collectors, separators, and electrolytes. These materials may decay during use, which may affect the cycle life of a battery.
It is not uncommon for overcharging LiFePO4 batteries to accumulate heat, which increases the temperature, shortens their lifespan, and increases the risk of fires and explosions.
Using lithium batteries involves a charging and discharging cycle, and the current size, cut-off voltage options and mode of operation all have an impact on their longevity. In order to reduce the life of your LiFePO4 battery and impair its functioning, it is not recommended to increase the working current, raise the charging cut-off voltage, or decrease the discharge cut-off voltage.
