Causes due to regular use1. Calendar aging Lithium-ion batteries are constantly degrading—even when they're not in use—simply as a consequence of time and thermodynamics. Overcharging and overdischarging.
Here are some general guidelines from the U-M researchers to maximize lithium-ion battery lifetime, along with a few specific recommendations from manufacturers: Avoid temperature extremes, both high and low, when using or storing lithium-ion batteries.
Lithium-ion batteries unavoidably degrade over time, beginning from the very first charge and continuing thereafter. However, while lithium-ion battery degradation is unavoidable, it is not unalterable. Rather, the rate at which lithium-ion batteries degrade during each cycle can vary significantly depending on the operating conditions.
What happens if you charge a lithium ion battery too fast?
Fast charging Though it may sound advantageous, fast charging contributes to accelerated lithium-ion battery degradation, because if you charge a lithium-ion battery too fast, you risk lithium plating. Lithium plating causes even more severe degradation than SEI does.
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.
Are high temperatures bad for lithium ion batteries?
High temperatures are always a cause for concern when it comes to lithium-ion batteries. Besides triggering potentially dangerous consequences, exposure to high temperatures also causes batteries to degrade more quickly, diminishing their lifetime overall.
What happens if you overcharge a lithium ion battery?
As with fast charging, overcharging a lithium-ion battery can result in lithium plating, which kicks off a rapid, snowball effect of degradation. It's worth noting that the anode can sometimes degrade more rapidly than the cathode.
