German mechanical engineering company IP PowerSystems has developed a new process for filling electrolyte into lithium-ion battery cells.
It said it is flexible and highly efficient and calls the system Direct Filling. It can be used for hardcase and pouch battery cells.
Toni Bläsche, product manager for IP PowerSystems, said his company has been specialising in battery cell assembly machines since 2017. In recent years, it has been selling electrolyte filling machines. Bläsche and his team have developed Direct Filling to enable research institutions and start-ups to fill their batteries with precision.
A dosing piston pump guarantees a very high level of filling accuracy. The filling status of individual cells and other important filling parameters are recorded and evaluated in real time.
For hardcase battery cells (cylindrical or prismatic), the company offers an electrolyte injector direct filling machine. The cells are evacuated and then filled with electrolyte up to 40 bar.
The company is expanding on the US market, where it set up a subsidiary last year, in Los Angeles, California.
