-
Chemical Phenomena: The electrolyte within the battery can degrade over time. This degradation may lead to gas formation, swelling, and rupturing of the battery. Additionally, dendrites, or lithium metal filaments, can grow during charging and cause internal short circuits.
Technical terms such as “thermal runaway” refer to the process where increasing temperature leads to more heat generation, escalated chemical reactions, and ultimately, uncontrollable conditions. “Electrolyte” is the conductive medium that allows lithium ions to move between the anode and cathode of the battery.
The specific conditions contributing to lithium-ion battery failure include:
- Overcharging: This can cause excessive heat and stress on the battery electrodes.
- High Temperatures: Exposure to extreme heat can accelerate degradation.
- Deep Discharge: Allowing the battery to discharge too much can lead to irreversible damage.
