The manufacturing process strongly affects the electrochemical properties and performance of lithium-ion batteries. In particular, the flow of electrode slurry during the coating process is key to the final electrode properties and hence the characteristics of lithium-ion cells, however it is given little consideration.
According to the literature, the Li-ion battery market value is expected to increase from about $34.2 billion in 2020 to $87.5 billion in 2027 . Advancement of technologies for electrode manufacturing has been among one of the main factors in the reduction of LiB costs by nearly 90% and 5 times increase in its volumetric energy since 2008.
Each batch for slurry preparation contained a total mass of 6 kg of AM to ensure that the mixing concepts discussed in this contribution are highly relevant to industrial processes. Three mixing and dispersing processes based on sequential addition procedures are compared.
The influence of industrial-suited mixing and dispersing processes on the processability, structure, and properties of suspensions and electrodes for lithium-ion batteries is investigated for the case of ultrathick NCM 622 cathodes (50 mg cm −2).
Consequently, demands for high quality and high-performance energy storage systems to support electric mobility is expected to rise significantly. Rechargeable lithium-ion battery (LiB) cells have proven to be a powerful technology due to their considerable energy, power density and long cycle life .
The coatweight and uniformity of the coating must be maintained to a tight tolerance, as the anode and cathode must be balanced in the final cell. The rheology and interfacial properties of the slurry, such as surface tension impact the coating parameters alongside the coating gap and material flow rate.
