Why do lithium polymer batteries swell?

In most cases, these components include oxygen. In the case of LiPo batteries, the polymeric nature of the electrolyte means that they also tend to produce carbon dioxide (CO2) and carbon monoxide (CO) when they decompose. The production of these gases is what causes a LiPo battery to expand and swell.

Can you fix a swollen lithium battery?

Can you revive a LiPo battery?

When the total voltage is equal to about 3.3 volts per cell you can move the battery over to your LiPo balance charger and balance charge at 0.5C rating. This will take longer than charging at 1C but is safer. Once the balance charge has completed balancing you should have a fully recovered LiPo battery.

Can a swollen battery fix itself?
