Measuring inhomogeneous pressure distribution in lithium-ion pouch cells during long-term ageing
Several studies have shown that applying the right amount of mechanical pressure on lithium-ion batteries can reduce their aging drastically. In research, this pressure is usually applied using stiff plates that apply either a nearly constant force by using springs or a constant strain with fixed rods. In contrast, the industry uses cushioning pads in […]
Recent progress in continuous slurry production – towards smart manufacturing of electrode slurries
