What Are Swollen Lithium Polymer Batteries and Why Do They Swell?

Swollen lithium polymer batteries are a common issue that can occur when these batteries are overcharged, damaged, or exposed to high temperatures, leading to safety hazards.

• Overcharging: Overcharging occurs when a battery is charged beyond its maximum voltage limit, causing an increase in internal pressure. This pressure can lead to the electrolyte inside the battery decomposing, producing gases that cause the battery to swell.
• Temperature Extremes: Exposure to high temperatures can accelerate chemical reactions inside the battery, leading to thermal runaway. This can cause the gas formation that results in swelling, as well as potentially dangerous situations such as leaks or fires if the battery ruptures.
• Physical Damage: Physical impacts or punctures can damage the battery’s internal structure, which can cause short circuits and gas buildup. Even a small breach can lead to swelling, as the internal components react to exposure to air or moisture.
• Age and Wear: As lithium polymer batteries age, their capacity diminishes, and they become more susceptible to swelling due to the breakdown of internal materials. This natural degradation process can lead to swelling even without external factors, making older batteries particularly risky.
• Improper Storage: Storing batteries in unsuitable conditions—such as in direct sunlight or in environments with extreme temperatures—can exacerbate swelling. Proper storage is essential to maintain battery health, as it helps prevent the conditions that lead to swelling from developing.

What Are the Main Causes of Battery Swelling?

The main causes of battery swelling include:

• Overcharging: Overcharging a lithium polymer battery can lead to excessive heat generation and chemical reactions within the cell, resulting in gas buildup and swelling.
• Excessive Discharge: Discharging a battery below its recommended voltage can cause irreversible damage, including swelling, as the electrolyte decomposes and gases are produced.
• High Temperatures: Prolonged exposure to high temperatures can accelerate the degradation of battery materials, leading to thermal runaway and the formation of gas, which causes the battery to swell.
• Physical Damage: Any punctures, dents, or impacts to the battery can compromise its structure, allowing for internal short circuits or chemical leaks that contribute to swelling.
• Aging: As lithium polymer batteries age, their internal chemistry can change, which may lead to gas generation and swelling, particularly if they have not been stored or used correctly.

Overcharging occurs when a battery is charged beyond its maximum voltage capacity, which can produce heat and increase internal pressure. This process can lead to the breakdown of electrolyte and separator materials, causing swelling as gases form.

Excessive discharge happens when a battery is drained too deeply, which can damage the internal components and cause the electrolyte to break down. This decomposition can produce gas that builds up inside the battery, resulting in swelling.

High temperatures can significantly affect battery performance and lifespan. When batteries are exposed to heat, especially in environments exceeding recommended storage temperatures, the risk of thermal runaway increases, which can lead to swelling due to gas accumulation.

Physical damage to a lithium polymer battery can occur from mishandling, dropping, or puncturing. Such damage can disrupt the internal structure, potentially causing short circuits or leakage of materials that generate gas, resulting in swelling.

Aging naturally affects lithium polymer batteries as the chemical reactions within them become less efficient over time. This degradation can lead to the production of gases, contributing to swelling, particularly if the battery has been improperly maintained or stored.
