Understanding the Fire Risks of Lithium-Ion Batteries

Lithium-ion batteries have become an indispensable part of our lives, powering everything from smartphones and laptops to electric vehicles and power tools. Countless Australian’s utilise these compact powerhouses on a daily basis, often times without even realising it. Whilst the convenience and efficiency of lithium-ion portable energy storage is well understood, the fire safety risks are not always clear. Here’s what you need to know about the safety hazards of lithium-ion batteries, and how you can keep your business and valuable assets safe from harm.  

Why are Lithium-Ion Batteries a Potential Fire Risk? 

In recent years there have been a number of news stories citing lithium-ion batteries as the cause of destructive fires. Despite their compact size, lithium-ion batteries contain a very high energy density which poses a unique set of fire safety challenges. Thermal runaway is one of the primary culprits behind lithium-ion battery fires, and this can occur when the internal temperature of the battery rises to a critical point. This results in excessive heat generation and gas release, which may ignite the flammable electrolyte liquid within the battery.  

There are several factors which can contribute to the initiation of thermal runaway, including: 

  • The presence of battery manufacturing defects 
  • Physical damage to the battery (dents, cracks, punctures etc.) 
  • Over charging or improper charging practices 
  • Prolonged exposure to high temperatures 

Lithium-Ion Safety Tips for Reducing Fire Risk 

When using lithium-ion batteries, ensure that you take the time to read the manufacturer’s directions and follow these directions. You should also be mindful of any changes or unusual occurrences with your batteries. Some symptoms of a problematic lithium-ion battery include changes in colour or shape, a visible leak, unusual odours, presence of smoke or a battery which is hot to the touch.  If you notice any of these issues, cease using the battery immediately and dispose of it at your nearest battery disposal point.  

To help keep your lithium-ion batteries in safe working condition, you should always practice the following: 

  • Charge your batteries/device in a clearly visible area free from clutter 
  • Keep batteries/devices at room temperature 
  • Make sure that any batteries, devices or chargers you purchase come from a reputable source and have undergone all necessary testing processes 
  • Keep batteries away from direct sunlight 
  • Avoid using double adapters when charging multiple devices. It is safest to attach a single device to a single charger, plugged directly into the wall outlet.  

Modern Safety Features of Lithium-Ion Batteries  

Battery manufacturers spend significant time and effort on developing new technologies and manufacturing processes to improve safety. Some lithium-ion battires on the market today are equipped with temperature sensors, pressure relief valves and flame-retardant materials which can minimize the impact of thermal runaway. They may also utilise battery management systems, whereby software monitors and controls the battery’s charging and discharging processes to reduce the likelihood of over-charging related fires.  

In general, modern lithium-ion batteries are safe to use. The most important thing is to maintain awareness of their condition and practice safe storage and charging methods as discussed above. It’s not worth risking a fire when defective batteries can be replaced quickly, easily and cost effectively.
