Aliant: The safety of Lithium in industrial applications.
A production characterized by 90% lithium iron phosphate batteries able to guarantee the highest levels in terms of safety In recent years, lithium batteries have become part of everyone’s daily life, starting with simple household appliances such as cordless vacuum cleaners, work tools, smartphones. To then reach the most interesting applications on automobiles and industrial machines with different uses.Speaking of lithium batteries, we often tend to generalize on a vast and complex technology which in its large family includes different chemical compositions. The numerous technologies differ with as many advantages and disadvantages for the application in which it will be used.
It is logical to think that the lithium technology used in the batteries of the most common smartphones is far from that used on industrial applications. The needs of the user of these systems are also very distant from each other. The number of recharge cycles in proportion to the cost of chemistry is a factor that often determines the choice of one rather than the other technology. Another important value are the dimensions available in relation to the energy density that chemistry can offer.In general, it can be said that the application and the required charging speed are among the most important factors that determine the technology suitable for the application.
Choose the technology that best suits your application:
At the base of all the variables considered, safety is undoubtedly the most important factor to consider. The service that the battery supplies undoubtedly requires a very high degree of safety and in Aliant we are discussing this.
Today, our production is characterized by 90% lithium iron phosphate batteries:
The technical and scientific data show that the use of this chemical in industrial applications guarantees the highest index in terms of safety – explains Federico Peluso, Aliant Sales Manager – We know from the first analyzes the use and workload that our batteries will have to support.The composition of the prismatic cells of Lithium Iron Phosphate usually in ABS plastic or aluminum, fully satisfy the needs of strength and solidity that our customers’ machines require.”
The strong vibrations and mechanical stress to which the machines are subjected impose rigid parameters in the production of the battery. Sometimes, in heavy duty applications, the safety of the entire pack is reasonably required from the shocks that the machine will suffer during its use. An already solid case on its own guarantees a much higher level of security than cylindrical cells and pouches.
Furthermore, during the perforation tests on common “18650” and “bag” cells, it is shown that the solid body capable of perforating produces numerous short circuits with relative criticalities on the entire battery. The Lithium Iron Phosphate, compared to its competitors, Lithium ions and Lithium polymer, guarantees a thermal escape temperature higher than 450/470 ° C, thanks to a very high chemical stability even in critical conditions.
We always try to analyze the customer’s request in order to propose the best solution in terms of reliability and safety of the entire package – continues Peluso – Starting from the choice of the appropriate chemistry for the application, obviously everything is constantly monitored by our BMS Pegasus thanks to the short-circuit and overvoltage protection systems, temperature sensors on each single cell that makes up the battery.”
Generally in industrial applications, the past has accustomed us to seeing large ventilation systems and dedicated battery recharging areas, regulated by strict standards. With Lithium all this is just a distant memory, both in the discharge and recharging phase.
We realize that, although Lithium technology has now become part of each of us, it still produces many doubts related to its real advantages – concludes Peluso – but even more about the real safety for those who use it. On the other hand, the new always raises a lot of unnecessary worries.”
