In particular, the market for thin film batteries is being driven by demand for technologies based on the internet of things (IoT), wearables, and portable electronics. The layers that comprise the anode, cathode, and electrolyte in thin film batteries are true to their name, with thicknesses on the order of microns (0.001 mm).
The layers that comprise the anode, cathode, and electrolyte in thin film batteries are true to their name, with thicknesses on the order of microns (0.001 mm). They are often deposited using physical vapor deposition, typically by thermal evaporation and sputtering.
There is no doubt that this pursuit will continue in the coming years. Dry film production technology eliminates solvent mixing, coating drying and solvent recovery steps of the traditional wet electrode process, greatly shortening the production process, and thus reducing the cost on energy consumption and equipment investment.
It is widely accepted in all of these applications that the process steps required for film production in general and the drying in particular are of paramount importance for film properties, which are governed by the film's internal structure or morphology , , , , .
The innovative manufacturing process significantly reduces energy consumption in electrode production and at the same time enables the drying speed to be doubled. © Fraunhofer ILT, Aachen, Germany. Laser drying in a roll-to-roll process makes the series production of lithium-ion batteries significantly more sustainable and economical.
The thicker the electrode, the more probable is the existence of disconnected solvent-filled clusters within the film that cannot be emptied by capillaries reaching to the film surface. In this investigation a model was successfully used to predict the drying curves of battery electrodes of different area weights.
