文摘

Cross-linked polymers generated from low molecular weight oligomers were investigated for the first time as electrode binders in lithium-ion batteries. With urethane acrylate-based binder precursors, electrode laminates of LiNi_1/3Mn_1/3Co_1/3O₂ (NMC) with good physical properties were prepared via a thermally initiated free-radical polymerization process. The cured NMC electrode was evaluated in both NMC/Li and NMC/MCMB cells and showed excellent cycling performance and C-rate capability.
