How Long do Lithium Batteries Last?

Lithium battery cycle life refers to the number of charge-discharge cycles a lithium battery can undergo before its capacity drops to a specified level. When you charge a lithium battery, lithium ions move from the positive electrode (cathode) to the negative electrode (anode) through an electrolyte. During discharge, these ions move back. Each

What Causes a Battery to Lose Capacity?

Solid Electrolyte Interface (SEI) Layer Formation: Lithium-ion batteries often form an SEI layer over time, which reduces ion movement and thus, battery capacity. Lithium Plating: This occurs when more lithium ions are deposited on the anode than can be intercalated, resulting in a reduction in battery capacity.

6 FAQs about [Lithium battery capacity drops to 80 ]

What is the capacity loss of Li-ion batteries?

The expected capacity loss of Li-ion batteries was uniform over the delivered 250 cycles and the batteries performed as expected. Eleven new Li-ion were tested on a Cadex C7400 battery analyzer. All packs started at a capacity of 88–94% and decreased to 73–84% after 250 full discharge cycles. The 1500mAh pouch packs are used in mobile phones.

What is the smallest capacity loss in a lithium ion battery?

The smallest capacity loss is attained by charging Li-ion to 75 percent and discharging to 65 percent. This, however, does not fully utilize the battery. High voltages and exposure to elevated temperature is said to degrade the battery quicker than cycling under normal condition.

Why do lithium-ion batteries get rated based on cycling based degradation?

Since this is a known phenomenon, many lithium-ion battery manufacturers will give their batteries a rating according to their cycling-based degradation. For example, a battery may be rated as being able to complete 1,000 full cycles before it degrades from full capacity to 80% capacity.

What if my battery capacity drops to 80%?

So in summary, if your battery capacity drops to near 80%, you should seriously consider changing it. If it happens within the 2-year warranty window (in some locations, it is sadly one year), return the phone and the battery to its manufacturer.

What is a lithium ion battery cycle life?

The cycle life specification of a lithium-ion battery is defined as the number of charge-discharge cycles this particular battery can support until it reaches 80% of its original capacity. The capacity of the battery fades (decreases) with every charge and discharge cycle.

How does charging and discharging affect lithium-ion battery degradation?

The cycle of charging and discharging plays a large role in lithium-ion battery degradation, since the act of charging and discharging accelerates SEI growth and LLI beyond the rate at which it would occur in a cell that only experiences calendar aging. This is called cycling-based degradation.
