Why Do Lithium-Ion Batteries Explode? Safety Tips for Aussies
G’day, mates! Powering your caravan for an epic outback adventure or keeping your campsite humming with a portable battery? Lithium-ion batteries are your trusty go-to.
But here’s a shocking stat: Fire and Rescue NSW reported 272 lithium-ion battery fires in 2023; over 5 blazes a week, with 63 more in early 2024, causing 7 injuries. Yikes!
At Topo DC Power, our Australian-made batteries are made to keep you powered safely. But those scary headlines about a lithium-ion battery explosion might have you wondering: Can lithium batteries explode? What happens if things go wrong?
Don’t sweat it. We’ll unpack the science, share some real-life incidents, and give you practical tips to stay safe.
What’s Inside a Lithium-Ion Battery? The Science Explained
Lithium-ion battery are the heart of many devices like your phone and laptop. They deliver heaps of energy for camping power solutions. But that power comes with risks.
Let’s explore how lithium-ion batteries work and why they can be risky.
A lithium-ion battery has three key parts: electrodes, electrolytes, and a separator. The electrodes (positive and negative) store energy. The electrolyte; a flammable liquid or gel, lets lithium ions flow between them, creating power. The separator prevents short circuits. This setup makes lithium battery rechargeable and reliable.
Compared to other batteries, li-ion battery offers higher voltage, greater capacity, and lower self-discharge, holding charge longer when idle. But here’s the catch: damage, overcharging, or overheating can disrupt this balance, causing thermal runaway. This can ignite the flammable electrolyte which leads to a lithium-ion batteries fire or, rarely, a lithium-ion battery explosion. No worries. Such incidents are uncommon, especially with our LiFePO4 batteries at Topo DC Power, built with safety features to minimise risks.
Why Do Lithium-Ion Batteries Explode? Causes & Real Aussie Incidents
The most glaring cause of li-ion battery exploding is manufacturing defects. Cheap materials or poor-quality control can introduce impurities or foreign particles which trigger short circuits and boost the risk of thermal runaway – a chain reaction that happens when a li-ion battery overheats rapidly, releasing energy that can spark fires or, in rare cases, explosions.
So, what triggers this breakdown? Let’s explore the causes, backed by real Aussie incidents, to show you what to watch out for.
| Cause | How It Triggers Trouble | Real Aussie Incident |
| Physical Damage | Dropping or crushing a battery causes internal short-circuits, sparking thermal runaway. | In March 2024, a tradesman’s toolbox in Lake Macquarie, NSW, caught fire when a damaged lithium-ion battery for a garden hedger ignited during transport, nearly causing a major blaze.

| Overcharging | Using non-approved chargers or overcharging overheats the battery, risking a lithium-ion batteries fire. | In December 2023, a toy car’s li-ion battery lithium exploded in Queensland while charging, sending flames to the ceiling and causing $8,000 in damage. The family barely escaped. Source: msn.com/en-au/news |
| Extreme Heat | High temperatures (e.g., hot cars or direct sunlight) can destabilise the battery’s electrolyte, leading to li-ion battery explode. | In January 2022, a cordless impact wrench’s lithium-ion battery exploded in a Northern Territory work vehicle after being left in the heat, wrecking the interior.

| Improper Storage | Can lithium batteries catch fire when not in use? Yes, if stored in hot, humid, or cramped conditions, increasing fire risk. | In March 2024, a loose lithium-ion battery in a Sydney garbage truck sparked a fire when compacted, one of over 1,000 battery-related fires in Australia that year. Source: abc.net.au |
| Manufacturing Defects | Cheap materials or poor-quality control introduce flaws (e.g., faulty separators), causing short-circuits and lithium-ion battery explosion. | In April 2024, a substandard mobile phone power bank exploded in Melbourne student accommodation, gutting a bedroom and evacuating 50 residents.

Don’t worry. Spotting a dodgy li-ion battery lithium before it fails can save you from a lithium-ion batteries fire or lithium-ion battery explosion. While lithium-ion batteries don’t always wave a red flag, there are tell-tale signs to watch for.
6 Warning Signs Your Lithium-Ion Battery Is Failing
Catching these signs early keeps your portable power systems and your adventures safe Here’s what to look out for, so you can act fast and avoid trouble.
- Overheating: If your device or batterie ion lithium feels unusually hot, especially near the battery, it’s a warning. Stop charging or using it immediately to prevent thermal runaway.
- Swelling or Bulging: A failing lithium-ion battery may expand, causing visible bulges or deformities. If your device looks puffed up, unplug it and stop using it pronto.
- Reduced Battery Life or Wonky Charging: Notice your battery dying faster or charging erratically? These are signs your li-ion battery lithium is struggling and needs checking.
- Strange Noises: Hissing or cracking sounds from your battery? That’s a red alert. A failing lithium-ion battery might be building up pressure, so act quickly.
- Weird Odours: A strong, chemical smell from your device or battery screams trouble. This could signal damage or leakage, so don’t ignore it.
- Smoke or Vapour: Seeing smoke? That’s a clear sign a lithium-ion batteries fire may have started. Evacuate, follow emergency steps, and call 000 for Fire and Rescue.
What to Do If a Lithium-Ion Batteries Fire Happens
If you’re facing a li-ion battery exploding or catching fire, stay calm and act fast:
- Evacuate Immediately: If you see smoke, sparks, or flames, get yourself and others to safety. A lithium-ion batteries fire can spread quickly.
- Don’t Use Water: Unlike regular fires, lithium-ion battery fires need special treatment. Water can make things worse by reacting with the battery chemicals.
- Use a Class D Fire Extinguisher: These are designed for metal fires, including lithium-based ones. If you don’t have one, smother the fire with dry sand or a fire blanket.
- Ventilate the Area: If it’s safe, open windows to clear toxic fumes.
- Call Emergency Services: Dial 000 in Australia to get professional help.
- Dispose Safely: Once the fire is out, don’t toss the battery in the bin. Take it to a recycling center that handles lithium-ion batteries.

How to Prevent an Exploding Lithium Battery
Preventing a li-ion battery explode is all about smart habits:
- Use Approved Chargers: Stick to the manufacturer’s charger to avoid overcharging, which can spark thermal runaway.
- Store Smart: Keep your batterie ion lithium in a cool, dry place, away from heat, humidity, or flammable materials.
- Inspect Regularly: Check for dents, swelling, or leaks. If your li-ion battery lithium looks dodgy, stop using it immediately.
- Charge Safely: Never leave batteries charging unattended, especially overnight. Avoid combustible surfaces like wood or carpet, and disconnect if you see swelling, smoke, or extreme heat.
- Recycle Right: Drop old or damaged lithium-ion batteries at approved recycling points, not household bins.
- Buy Quality: Opt for trusted brands like Topo DC Power. Our LiFePO4 batteries have built-in protections against overcharging, overheating, and short circuits.
