Because of their high efficiency and low weight, lithium-ion batteries have become an integral part of electric cars, battery-operated screwdrivers and smartphones. However, such batteries harbour considerable risk of fire if they become damaged. Retailers of e-bikes, e-cars or battery-operated tools are therefore faced with the challenge of safely storing defective batteries or securely transporting them back to the manufacturer. Michael Blum, ZARGES Product Manager, reveals what you should take note of when transporting defective lithium-ion batteries.
Improper storage or charging of a lithium-ion battery may cause damage to it; in the worst case, this may even cause a fire. This is why such batteries are considered dangerous goods. What should we take note of when transporting lithium-ion batteries?
Blum: First and foremost, the product must be secured, and a suitable packaging must be found. For this process, all provisions in regulations concerning dangerous goods and their packaging must strictly be followed. In addition, there are specific regulations to follow depending on the mode of transport (by road, rail, sea or air). For example, the ADR (European Agreement concerning the International Carriage of Dangerous Goods by Road) is applicable to transport by road, while provisions in the IATA (International Air Transport Association) Dangerous Goods Regulation are to be followed for transport by air. The IMDG Code is applicable to maritime transport of dangerous goods.
ZARGES has developed a new case that is especially designed for storage and transport of damaged batteries. How did this come about?
Blum: Because rechargeable batteries are very sensitive, it is possible that retailers are required to deal with damaged batteries. One of our customers approached us with this challenge. We developed a solution together with a team of experts comprising our internal specialists and the customer. ZARGES' decades of experience in packaging solutions for lithium-ion batteries played a decisive role in this process. That is how the new "K 470 Battery Safe" case came about.
How well can the ZARGES dangerous goods case prevent a fire?
Blum: One special feature of the case is its interior, which is neither flammable nor electrically conductive. If a lithium-ion battery ignites, the case's interior will foam up and prevent the fire spreading. The underlying principle: the special absorbent material ensures that solid components are filtered out of the battery gases and liquid constituents condense on the fibre surface. This is how the aluminium case prevents the leaked flammable gases from igniting. Thanks to the reduced fire risk, service centres will be able to safely transport even damaged batteries.
