Lithium Ion Batteries are quickly becoming the norm for many of our customers. It is important to know that they can be a safety hazard since they contain a flammable electrolyte, and if damaged or incorrectly charged can lead to explosions and fires.
Failure in these batteries can create “Thermal Runaway“
- Overcharging heats up the electrolyte/chemicals inside causing exothermic reaction
- The hot chemicals will degrade the separator
- When the separator is breached, it causes a short circuit
- Thermal runaway occurs
- Thermal runaway occurs most often in a battery when the internal heat generation exceeds the rate at which the heat can be expelled.
