What causes phone batteries to expand?
What Causes a Swollen Battery? The most common cause is an overcharge of the battery, which causes a chemical reaction between the electrodes and the electrolyte, resulting in the release of heat and gases that expand inside the battery, causing the casing to swell or even to split open.
Can a phone battery be repaired?
Like your car, they might just need a new part every now and then, and the best repair you can do on your phone to make it last longer is a battery replacement. But most batteries aren’t user-replaceable.

The most common cause of rechargeable battery bloating, however, is when a rechargeable battery is overcharged and therefore exposed to too much heat.
Why is my phone battery swelling up?
Why do phone batteries swell? Like a lot of things in life, the reason why phone batteries swell comes down to chemistry. Tech repair site iFixit provides a smart overview, but it basically boils down to stoichiometry. Lithium-ion batteries rely on a chemical reaction to charge.
Why is there a gas coming out of my phone battery?
The gases are produced due to electrochemical oxidation of the electrolyte.
