What causes a battery to degrade?

Each time a battery goes through a charging and discharging cycle, it undergoes stress that contributes to its degradation. The depth of discharge, or how much the battery is drained during each cycle, can impact the rate of degradation. Deep discharges and high charge rates can accelerate degradation.

What is battery degradation?

Battery degradation refers to the gradual loss of a battery's ability to hold charge and deliver the same level of performance as when it was new. This phenomenon is an inherent characteristic of most rechargeable batteries, including lithium-ion batteries, which are prevalent in various consumer electronics and electric vehicles.

How do you manage your batteries for long-term success?

To best manage your batteries for long-term success, look instead for ways to gain more actionable insights, allowing you to pinpoint opportunities to reduce battery degradation and increase the lifespan of your fleet.

What causes a battery to decompose?

Thermal events can destabilise the SEI and cause it to decompose and compromise the battery’s safety. An electrically insulating porous layer in a LIB that prevents the anode and cathode touching, which would cause a short circuit. State-of-health is a measure of the condition of a battery, compared to its ideal condition.

How do you know if a battery is degraded?

If your battery gauge displays that you have a significant amount of power remaining and then it suddenly dies, it is a likely symptom of a degraded battery. Lithium-ion batteries differ from nickel-cadmium ones in that they power your device at full capacity until the battery runs out of juice.

How often should you recharge a lithium ion battery?

Recharging your lithium-ion battery after 20% to 30% of use helps you increase the chances of extending your battery’s life. The one exception is that once a month, it is recommended to let your battery run down to about 5% capacity before recharging.
