Are li-ion batteries a fire hazard? In the meantime, nearly all manufacturers of industrial trucks are selling their warehouse technology devices with lithium ion batteries, even some forklifts are already available with these comparably new energy storage systems. In everyday practice, they offer invaluable advantages as they are not subject to the typical limitations of a standard lead-acid battery. Li-ion batteries can be charged very quickly, so that batteries no longer need to be changed even during multiple-shift operation. They also have a significantly higher volumetric capacity, increased charging energy efficiency and a longer service life expectancy. In addition, they are also maintenance-free. Overall, this all sounds very positive. If lithium batteries are used correctly, they do not pose a risk However, there are also some critics who believe that the new technology does pose some risks. These are certainly justified, as lithium is a highly reactive alkali metal. The softest of all solid elements, it even reacts with water and if touched it will cause chemical and physical burns due to skin moisture levels. These characteristics mean that a fire of a lithium battery cannot be extinguished with water. Other sectors have already hit the headlines for using this type of battery. The Dreamliner aircraft model from Boeing was grounded on a global scale for three months due to problems with the li-ion batteries. The media also reported about electric vehicles that caught fire following an accident. Are the new batteries a fire hazard? The German Environment Agency (UBA) has issued a general statement about lithium batteries and gives the all-clear as long as batteries are used and stored correctly. If handled correctly they can be deemed to be safe. However, it should be noted that if lithium-ion batteries are overcharged or totally discharged, they can react in a highly sensitive way. External influences, such as mechanical damage or a heat supply, can cause the battery to overheat which can subsequently cause a fire or an explosion. This is why each battery system must always include an intelligent electronic control system. Ultimately, manufacturers are required to design the overall system in such a way that the risk of this occurring is excluded. Holger Seybold (Editor-in-chief) EDITORIAL STORAGE. PRODUCTS. FLOW. In the world of logistics everything needs to keep moving. Whether automatically or manually, the seamless transport of goods; receiving, storage, or retrieval, is the key to excellent logistics. We‘ve designed our containers exactly with this in mind. Our containers are versatile and can be used in a number of different storage and handling systems. They work at every stage of the logistics chain so that everything runs like a clockwork. www.bekuplast.com Visit us at the CeMAT! 31.05.–03.06.2016 Hall 13 · Stand E11 Industriestraße 1 · 49824 ·Ringe ·Germany Tel. +49 5944 9333-0 ·info@bekuplast.com
