Fire protection during storage of lithium batteries

Fire protection during storage of lithium batteries

Lithium batteries are highly efficient energy storage media that are ideal for a wide range of applications. Considering the burgeoning demand for energy, storing energy has an especially important role to play. That means that the need for high-performance batteries will continue to increase.

The benefits of lithium batteries

  • They have a high level of cell voltage
  • There is no memory-effect with secondary batteries (they are rechargeable where primary batteries are not)
  • Low level of self-discharge

These properties are making lithium batteries increasingly popular in many areas of everyday-life and industry. With the breath-taking increase in lithium battery applications, manufacturers, installers and users also have to increasingly come to terms with safety. For instance, technical defects or incorrect handling of these batteries when storing, charging or operating them can cause the energy stored to be discharged in an uncontrolled fashion, which often causes fires.

The benefits of Li batteries with respect to flexible usage possibilities and greater performance also entail an increased fire risk at the same time.

“The energy contained in a 13 kWh lithium-ion storage battery matches that of 4 kg of dynamite.”

Volker Müller from Hessian distribution network operator ovag Netz AG

Businesses must take this elevated fire risk into account while storing batteries or during the active operation of battery storage devices.

Insurance provider FM Global and the Association of German Insurers (GDV) warn:

„…special precautions are necessary for storing Li-Ion batteries!“

The solar industry sees it the same way. The current guideline for battery storage systems contains the following recommendation, here too:

„Special fire-protection measures to avoid fire cross-over and the transmission of internal and ex-ternal fires are to be taken during the operation of Li battery storage systems.“
