What is the cycle life of a lithium ion battery?

The cycle life of a lithium-ion battery refers to the number of charge and discharge cycles it can undergo before its capacity declines to a specified percentage of its original capacity, often set at 80%.

How long does a lithium battery last?

For example, after 500 cycles, a typical lithium battery may retain only 80% of its original capacity. Proper usage can significantly reduce this degradation, extending the battery’s usable lifespan. To maximize cycle life, avoid full discharges and charge the battery partially, as frequent deep cycles can accelerate wear. Part 3.

Why do lithium batteries have a higher cycle life?

A higher cycle life indicates better durability and longevity of the battery. The cycle life of a lithium-ion battery is often influenced by the depth of discharge (DoD), and deep discharges can have implications on the overall longevity of the battery.

How long does a Li-ion battery last?

Manufacturers take a conservative approach and specify the life of Li-ion in most consumer products as being between 300 and 500 discharge/charge cycles. In 2020, small wearable batteries deliver about 300 cycles whereas modern smartphones have a cycle life requirement is 800 cycles and more.

What is the deep discharge cycle life of a lithium-ion battery?

The deep discharge cycle life of a lithium-ion battery refers to the number of cycles the battery can undergo when discharged to a significantly low level, typically a lower state of charge (SOC) than regular operational conditions.

Does storing a lithium ion battery affect calendar life?

Storing a battery at a high state of charge can contribute to degradation over time, impacting both calendar life and shelf life. In the realm of lithium-ion batteries, comprehending cycle life, calendar life, and shelf life is pivotal for users and manufacturers alike.
