Lithium Werks highlights safety of LFP battery tech

LinkedIn +

Lithium Werks has underlined the safety and security of its lithium-iron-phosphate cell technology following the news of a battery fire aboard a ferry in Norway.

Rather than the more common nickel-manganese-cobalt technology (NMC), Lithium Werks’s LFP configuration uses smaller cylindrical cells rather than the larger prismatic type, reducing the amount of energy released in the event of a failure.

In addition, the different chemistry in LFP cells makes thermal runaway significantly less likely to occur, while each Lithium Werks cell has its own current interrupt device that will stop current flow in the event of an abnormal condition. The battery management system also monitors a series of parameters in each cell block, and can give a warning or even induce a system shutdown if required.

A further benefit of the lithium-iron-phosphate arrangement is that its use in the U27-24XP module means it has DNV-GL type approval, reducing the amount of safety equipment required for installation.
