Why do lithium batteries expand?

This expansion can be problematic in lithium batteries, where tightly packed components have limited space to expand. Excessive heat, often generated during rapid charging or discharging, can lead to the expansion of internal components and, consequently, the battery casing.

How do you store a lithium battery?

Proper storage of lithium batteries is crucial for maintaining their integrity and minimising the risk of damage. Follow these guidelines for safe battery storage: Store batteries in a cool, dry place with stable temperatures. High temperatures can accelerate the risk of thermal runaway.

Can You puncture a swollen lithium-ion battery?

Do not ever try to puncture the bulge in your lithium-ion battery. Swelling of lithium-ion batteries is caused due to heat and build-up of gases, which make the battery vulnerable. Puncturing a swollen lithium-ion battery may lead to fire and explosion.

How do you maintain a lithium battery?

Regular maintenance of lithium batteries can help identify potential issues and prevent damage. This includes inspecting the batteries for damage and cleaning the battery terminals. Have batteries removed by your waste contractor on a regular basis and in line with your legal waste authorisations / exemptions.

What causes irreversible expansion in lithium ion batteries?

Irreversible expansion always occurs as a result of a degradation mechanism, such as oxygen evolution, dendrite formation, electrode decomposition or others – see “ Lithium ion battery degradation: what you need to know ” by J. Edge et al. for more background on mechanisms.

How do lithium batteries store and release energy?

In lithium batteries, energy storage and release occur through the movement of lithium ions between the anode and cathode. During charging, ions move from the cathode to the anode, storing energy. During discharge, these ions travel back to the cathode, releasing energy for the device’s use.
