Lithium-ion batteries power our cell phones, laptops, and tablets. They are also widely used in workplace devices like power tools, medical equipment, body cameras, and smart PPE. Their rechargeable nature and high energy density make them perfect for various commercial applications.
However, these same features can also pose potential hazards. The significant energy stored in lithium-ion batteries can lead to overheating, which might cause fires or explosions.
While lithium-ion batteries are generally safe, it’s crucial to understand some key points to ensure the safety of your workers and facilities.
How Lithium-Ion Batteries Work
To grasp why lithium-ion batteries can be hazardous, it helps to understand their operation. Here’s a quick overview:
- Energy Production: When in use, chemicals inside the battery break down, producing ions and electrons.
- Energy Flow: These ions move from one end of the battery, generating a flow of electrons to release energy.
- Rechargeability: Unlike regular batteries, this process can happen multiple times in lithium-ion batteries. Chargers reverse the ion flow, restoring the battery’s energy.
- Degradation: Over time, this cycle wears out the battery, eventually reducing its ability to hold a charge.
Why Lithium-Ion Batteries Fail
Although failures are rare (only about two or three per million battery packs), they can occur due to damage or manufacturing defects.
Some common causes of damage include:
- Exposure to Water or High Temperatures: These conditions can harm the battery’s integrity.
- Physical Damage: Dropping, crushing, or puncturing the battery can lead to failure.
- Improper Handling: Using excessive force to remove batteries from devices can also cause damage.
When lithium-ion batteries fail, they can enter a state called thermal runaway, where the released heat triggers a chain reaction, potentially leading to fires or explosions.
Lithium-Ion Battery Safety Precautions
Most risks associated with lithium-ion batteries can be mitigated by following simple safety precautions:
- Purchase from Reputable Sources: Ensure batteries come from a trusted manufacturer or supplier.
- Avoid Overheating: Unplug devices once they are fully charged.
- Proper Storage: Keep batteries in a cool, dry place away from flammable materials.
- Handle Damaged Batteries Safely: If a battery shows signs of damage, such as leaking, bulging, or overheating, remove it from service immediately and place it in a non-flammable material like Cell Block.
- Dispose of Batteries Properly: Never throw lithium-ion batteries in the trash. Contact experts like Union Battery for proper disposal.
