Can a lithium battery die suddenly?
The good news is that lithium batteries usually don’t die suddenly. Instead, they slowly lose their capacity over time until they can no longer hold a charge. There are a few things that can cause a lithium battery to die prematurely. One is heat exposure. If a lithium battery gets too hot, it can start to degrade and lose its capacity quickly.
What can shorten the life of a lithium battery?
One is heat exposure. If a lithium battery gets too hot, it can start to degrade and lose its capacity quickly. This is why it’s important to keep laptops and other devices that use lithium batteries in cool, dry places. Another thing that can shorten the life of a lithium battery is deep discharging.
What happens if a lithium battery degrades?
This is called calendar aging, where the battery degrades as a function of time. Calendar aging is unavoidable because the degradation occurs even when there is zero battery usage. What happens when a lithium battery degrades? When a lithium battery degrades, end users will notice lower capacity and reduced power capability.
What happens when you charge a lithium-ion battery?
When you charge a lithium-ion battery, the lithium ions move from the negative electrode to the positive electrode. This creates an imbalance in the electrons and causes degradation of the battery over time. The good news is that there are ways to help prolong the life of your lithium-ion battery.
How does lithium loss affect battery capacity?
Both modes of lithium loss reduce the charge “currency” or lithium inventory, and thus the battery’s capacity, because there will be a diminished amount of lithium freely available to convey charge between the positive and negative electrodes.
What happens if a lithium battery fails?
(ii) In a worst-case scenario, the metallic lithium can grow into branch-like structures called dendrites, which can protrude through the insulating separator and short-circuit the battery. This can cause a catastrophic failure mode, as has been seen in high-profile EV fires covered in the media.
