Lithium-ion batteries and accumulators are an integral part of our daily lives. They power smartphones, laptops, power tools, electric vehicles, and stationary energy storage. Despite their widespread use, they are still surrounded by many uncertainties, half-truths, and myths. Media reports about fires or explosions further contribute to amplifying fears. Thus, it is all the more important to differentiate between real risks and widespread misconceptions.
In principle, lithium-ion batteries are very safe when manufactured and used correctly. Risks primarily arise when batteries are damaged, improperly charged, inadequately stored, or exposed to extreme temperatures. Modern protective mechanisms and battery management systems significantly reduce these risks. Nevertheless, numerous myths persist that often lead to improper behavior or unnecessary concerns.

Myth 1: Lithium-ion batteries can explode at any time without warning.
This myth is widespread but not true. In general, explosions or fires are caused by clear factors such as overheating, mechanical damage, manufacturing defects, or improper charging. Modern batteries come equipped with multiple safety systems that can detect dangerous conditions early and initiate countermeasures.
Myth 2: Every lithium-ion battery is a ticking time bomb.
Lithium-ion batteries are not inherently dangerous products. Millions of batteries are safely used daily. The risk only increases with improper handling, such as using cheap products without tested safety standards or if there are visible damages to the battery.
Myth 3: A battery should never be charged overnight.
Charging overnight is generally safe for high-quality devices. Modern charging electronics automatically stop the charging process once the battery is full. However, it can become dangerous when using substandard chargers or damaged batteries.
Myth 4: Heat is harmless to lithium-ion batteries.
High temperatures are one of the greatest dangers for lithium-ion batteries. They accelerate aging, reduce capacity, and can lead to thermal runaway in extreme cases. Batteries should never be exposed to direct sunlight or high ambient temperatures.
Myth 5: Cold temperatures permanently destroy lithium-ion batteries.
Cold temperatures usually don’t permanently damage a battery but can significantly impair its performance temporarily. It becomes critical when a heavily cooled battery is immediately charged with high power.
Myth 6: Fully discharging a battery extends its lifespan.
On the contrary: deep discharges heavily strain lithium-ion batteries and can cause permanent damage. For a long lifespan, it’s better to keep the charge level between twenty and eighty percent.
Myth 7: Only old batteries are dangerous.
New batteries can also pose risks due to manufacturing defects or transport damage. While older batteries have a higher failure risk, the condition is always more critical than just the age.
Myth 8: Swollen batteries are still usable?
A swollen battery is a serious warning sign. It should not be used or charged further, as there is a high risk of fire and explosion. Such batteries must be disposed of properly.
Myth 9: All lithium-ion batteries are the same.
However, there are significant differences in terms of quality, chemistry, design, and safety level. Batteries from certified production with built-in protection circuits are significantly safer than simple or untested products.
Myth 10: A battery cannot catch fire if it’s turned off.
Even a powered-off device contains a charged battery. Internal faults, external heat, or mechanical impacts can still lead to dangerous reactions.
Myth 11: Water reliably extinguishes any battery fire.
Lithium-ion fires are difficult to extinguish. While water can cool, it is not always sufficient to prevent re-ignition. Special extinguishing agents and a sufficiently large amount of water are required for this.
Myth 12: Lithium-ion batteries are fundamentally harmful to the environment.
While their production is resource-intensive, they play a crucial role in the energy transition. Through recycling, a longer service life, and technological advancements, their environmental impact can continuously improve.
Conclusion: Lithium-ion batteries are powerful.
Efficient and safe when used properly. Many of the circulating myths either lead to unwarranted fears or to incorrect behavior. A well-founded understanding of the real risks is crucial for using batteries safely, avoiding damage, and responsibly leveraging the benefits of this technology.

The smoke gases produced in fires involving lithium-ion batteries are highly toxic and significantly hazardous to health. They pose one of the greatest risks in such fires—often even greater than the flames themselves.
Composition of the Smoke Gases
In the event of a fire or thermal runaway, electrolytes, plastics, metals, and cell components decompose. This process produces among others:
Particularly critical is hydrofluoric acid, as it penetrates deeply into tissues, causes severe burns, and can also have delayed, lethal effects.
Health Hazards
Inhaling the smoke gases can lead to severe health issues after a short period:
Many symptoms may appear delayed, which further increases the risk.
Why Lithium Fires Are Particularly Dangerous
Lithium-ion fires generate very high temperatures and release their gases suddenly. Additionally, batteries can flare up multiple times, even after the fire seems to be extinguished. The resulting smoke gases are difficult to predict and spread quickly, especially in enclosed areas.
Action in Case of Fire
Smoke from lithium-ion fires is extremely toxic and poses an acute threat to life. Even small amounts can cause severe health damage. Therefore, self-protection, swift evacuation, and proper conduct in the event of a fire are of the utmost priority.
Lithium fires are so difficult to extinguish because they fundamentally differ from normal fires. In lithium-ion batteries, energy is stored very densely, and during a malfunction or overheating, an uncontrolled chemical reaction occurs. This releases oxygen from within the battery, meaning the fire is not dependent on external oxygen and can continue to burn even when one tries to suffocate it.
Additionally, extremely high temperatures can heat nearby battery cells and trigger a chain reaction. This so-called runaway reaction causes the fire to spread further. Even when the fire seems to be extinguished, the battery can rekindle hours or days later because there is still energy present inside.
While water can cool, it evaporates very quickly and does not always reach all the hot areas. Therefore, large amounts of water and extended cooling times are necessary. At the same time, toxic and flammable gases are produced during the fire, making extinguishing even more challenging and dangerous.
In short: Lithium fires are hard to put out because they have their own oxygen sources, burn extremely hot, spread in a chain reaction, and are prone to reignition.
