Therefore, the environment and operators are protected against the carcinogenic and toxic nature of the NMC powder allowing a safe and clean workplace. The pressure vessel and its elements are gas and dust tight and monitored regularly. Lithium-Nickel-Manganese-Cobalt-Oxide (LiNiMnCoO2), abbreviated as NMC, has become the go-to cathode powder to develop batteries for power tools, e-bikes and. With the Gericke PulseFlow ® PTA system a high solids loading can be achieved, which minimises the consumption of pressurised gas and finally reduces the energy consumption for the production of compressed and dried air. The powders are very sensitive to moisture and thus dried air must be utilised for preventing the powders to form lumps. Therefore, the complete conveying system (pressure vessel, its accessories and pipeline) was equipped with different kind of wear protection coating. No contamination coming from metallic wear is accepted in the powder because it could cause later a short circuit in the battery. With the Gericke PulseFlow ® PTA conveying system a pressure vessel is used for transporting the powders as slowly moving product plugs. Due to the abrasive character a low velocity dense phase conveying system was chosen against a lean phase conveying system to minimise wear effects in the conveying line. Lithium rich (Li-rich) transition metal oxide cathodes are considered to be among the most promising intercalation cathode materials used for lithium-ion batteries (LIBs) with their high energy density above 900 Wh/kg. NMC powder usually has a high bulk density larger than 1.5 kg/l and are considered abrasive. High tap density, suggested tap density of the electrode >3.45g/cc. For a global chemical company Gericke delivered multiple pneumatic conveying systems to unload the powders from IBC and to convey to further production processes placed up to 50m away from the unloading point. Final assembly of senders for pneumatic conveying systemsįor the production of rechargeable batteries cathode material, typically fine lithium nickel manganese cobalt oxide (NMC) powders are utilized.
