The article conveys some information:
Although being incorporated in com. lithium-ion batteries for a while, the weight portion of silicon monoxide (SiOx, x ≈ 1) is only < 10 wt% due to the insufficient cycle life. Along this line, polymeric binders that can assist in maintaining the mech. integrity and interfacial stability of SiOx electrodes are desired to realize higher contents of SiOx. Herein, a pyrene-poly(acrylic acid) (PAA)-polyrotaxane (PR) supramol. network is reported as a polymeric binder for SiOx with 100 wt%. The noncovalent functionalization of a carbon coating layer on the SiOx is achieved by using a hydroxylated pyrene derivative via the π-π stacking interaction, which simultaneously enables hydrogen bonding interactions with the PR-PAA network through its hydroxyl moiety. Moreover, the PR's ring sliding while being crosslinked to PAA endows a high elasticity to the entire polymer network, effectively buffering the volume expansion of SiOx and largely mitigating the electrode swelling. Based on these extraordinary physicochem. properties of the pyrene-PAA-PR supramol. binder, the robust cycling of SiOx electrodes is demonstrated at com. levels of areal loading in both half-cell and full-cell configurations.

Di(1H-imidazol-1-yl)methanone(cas: 530-62-1) is a coupling agent in the synthesis of dipolar polyamides for nonlinear optical applications and polypeptides. It also used to make β-keto sulfones and sulfoxides, lead sequestering agents, and β-enamino acid derivatives.Safety of Di(1H-imidazol-1-yl)methanone
