The battery cell prototype introduced by SOLiDIFY has an vitality density of 1070 Wh/L and, in line with the consortium, is significantly larger than the 800 Wh/L of at this time’s lithium-ion battery know-how. The manufacturing course of must also be cost-effective and adaptable to current manufacturing strains for lithium-ion batteries. The prototype was created within the EnergyVille laboratory in Belgium, whereas the revolutionary electrolyte was developed by the Belgian Interuniversity Microelectronics Centre, the Swiss Federal Laboratories for Supplies Testing and Analysis and the French firm Solvionic.
In line with the venture members, the excessive vitality density of the pouch cell was achieved by combining a ‘thick’ cathode with NMC chemistry, a skinny lithium-metal anode and a skinny strong electrolyte separator. For the electrolyte, “a polymerized ionic liquid-based strong nanocomposite materials was used,” in line with the researchers. Moreover, “This method efficiently created a skinny separator of 20 μm, allowed for the usage of a thick cathode of 100 μm, and resulted in a compact battery cell stack.”
As well as, the consortium, which has existed since 2020, says it has succeeded in overcoming earlier weaknesses equivalent to mechanical energy and cathode impregnation, decreasing the cell’s charging time to a few hours and growing its service life to 100 cycles. The subsequent steps embody ‘additional upscaling this high-performance battery know-how’, in line with the venture members. Nonetheless, they’ve already said that the tactic ‘guarantees an inexpensive switch to business’ because of a producing course of that may be carried out at room temperature, might be tailored to present manufacturing strains and is predicted to value lower than 150 euros per kWh.
The SOLiDIFY consortium consisted of the analysis establishments Interuniversity Microelectronics Centre/EnergyVille (Belgium), Fraunhofer (Germany), Centro Ricerche Fiat SCPA (Italy), Empa (Switzerland), Hasselt College/EnergyVille (Belgium) and Delft College of Know-how (Netherlands) in addition to the economic companions VDL Groep (Netherlands), Umicore (Belgium), Solith (Italy), Solvionic (France), Sidrabe (Latvia), Leclanché (Switzerland), Gemmate Applied sciences (Italy) and Powall (Netherlands). The venture was funded by the EU’s Horizon 2020 analysis and innovation programme and coordinated by the Interuniversity Microelectronics Centre.
