High-Speed Fabrication of Lithium-Ion Battery Electrodes by UV-Curing
In this study, UV-curing was investigated as an alternative method to provide fast production of composite cathodes and significantly reduce the time and energy required for solvent removal in lithium-ion battery fabrication. To serve our purpose, low-molecular-weight polysiloxane acrylate (PSA) was designed and synthesized from a polysiloxane epoxide precursor. In the presence of the acrylic acid additive LiNi1/ 3Mn1/3Co1/3O2 (NMC), electrode laminates containing 10 wt% PSA binder were successfully fabricated by UVcuring. The cured electrode exhibited good mechanical and electrochemical properties. At current rates up to C/3, the cell performance of the UV-cured NMC electrode was comparable to that of conventional polyvinylidene fluoride (PVDF)-bound NMC electrode. Our initial success in applying high-speed UV-curing in composite electrode fabrication has proved that it is a promising route to substantially reducing the capital and operation costs of lithium-ion battery electrode manufacturing and additionally bringing about important environmental benefits.
