High Power Batteries
High-current lithium-based batteries are commonly used in compact and portable equipment where downtime or unplanned maintenance does not create financial risks. However, in a growing number of industrial markets, battery storage must be based on safe and reliable technologies to ensure long life and meet energy needs regardless of weather conditions and equipment life.
The ultra-high performance batteries developed in our laboratory, which can be manufactured with a discharge rate of up to 60C, can be considered the turning point in terms of safety, reliability and performance. Our batteries are based on different cell chemistries (classical, specialized) and are used in numerous industries.
Dry Coating
The fabrication of heavy-duty electrodes is a promising approach to increase the energy density of Li-ion batteries due to a favorable ratio of active to inactive materials. However, modern tape casting processes with relatively high solvent content are limited in terms of layer thickness and drying process, and are accompanied by undesirable effects such as binder migration. Therefore, advanced processes for electrode fabrication are urgently needed.
Fraunhofer ISIT has developed a dry coating process that does not require any solvents at all. Drying the coated electrode slurry is an energy-intensive process. It also requires a large amount of space, as long drying distances are necessary for an optimal process result. The dry coating process developed by Fraunhofer ISIT eliminates the need for solvents.
In addition, higher loadings are possible, which exceed the range of conventional electrodes. This leads to significant cost savings and is more environmentally friendly.
