Abstract:
In an effort to investigate the capabilities of a cross-linked polymer containing hydroxyl groups (-OH groups) as a binder for silicon (Si) negative electrodes in Li-ion batteries (LIBs), a Si/carbon black (CB)/(poly)pentaerythritoltriacrylate (PPETA) composite (Si/CB/PPETA-composite) electrode was fabricated through a curing process from a Si/CB/pentaerythritoltriacrylate (PETA) multifunctional monomer composite mixture (Si/CB/PETA-composite mixture). As a result, the delithiation of the Si/CB/PPETA-composite was nearly four times higher than that of a Si/CB/poly(vinylidene fluoride) (PVdF) composite (Si/CB/PVdF-composite) using the existing PVdF binder for 15 cycles. The lithiation of the Si/CB/PVdF/PPETA (1:2)-composite (approximately 2846 mAh g-1) using amixed PVdF/PPETA (1:2) binder (PVdF/PPETA (1:2) binder) (mixing ratio, 1.0/2.0) was improved by approximately 487 mAh g-1 compared to that of a Si/CB/PVdF-composite (about 2359 mAh g-1.
