Structural diversity and low cost make organic materials ideal candidates for next-generation energy storage applications. To obtain high-performance electrode materials for lithium (Li)-organic batteries, the identification of suitable organic mols. that exhibit multiple and stable redox states, limited solubility, and improved conductivity is critical The leverage of bio-derived redox-active motifs holds great promise due to their built-in functionality and availability from natural resources. Here, we report the structural evolution from naturally occurring, two-electron accepting carbonylpyridinium units into four-electron accepting small organic mols. and their incorporation into high-performance polymers. Impressively, CP2-based electrode can read up to 807 mAh g-1 after 300 cycles at a c.d. of 0.2 A g-1. The superior battery performance rivals that of state-of-the-art Li-ion batteries and opens the door toward significantly broadening the impact of this critical energy-storage technol. In the experiment, the researchers used many compounds, for example, Phenyl(pyridin-2-yl)methanone (cas: 91-02-1Quality Control of Phenyl(pyridin-2-yl)methanone).
Phenyl(pyridin-2-yl)methanone (cas: 91-02-1) belongs to pyridine derivatives. Pyridine has a dipole moment and a weaker resonant stabilization than benzene (resonance energy 117 kJ·mol−1 in pyridine vs. 150 kJ·mol−1 in benzene). Reduced pyridines, namely tetrahydropyridines, dihydropyridines and piperidines, are found in numerous natural and synthetic compounds. The synthesis and reactivity of these compounds have often been driven by the fact many of these compounds have interesting and unique pharmacological properties.
