Arai, Hajime; Yaguchi, Atsuko; Nishimura, Yoshihiro; Akimoto, Yuya; Ikezawa, Atsunori published an article in 2021. The article was titled 《Operando Optical Analysis of LiFePO4 Composite Electrodes》, and you may find the article in Journal of Physical Chemistry C.Quality Control of Vinylene carbonate The information in the text is summarized as follows:
Elucidating reaction inhomogeneity of composite electrodes is key to improve the performances of batteries such as rate capability and durability. Because the reaction inhomogeneity often disappears after a certain relaxation period, operando anal. techniques are indispensable. We hereby propose that operando optical anal. as a common lab method can be applied to visualize the reaction inhomogeneity of LiFePO4 composite electrodes for lithium-ion batteries with sufficient space and time resolutions The results indicate that the brightness of the charged phase was higher than that of the discharged phases, which can be used to sep. the phases and thus to elucidate the reaction inhomogeneity in the cross section of the composite electrode. A metastable phase Li3/4FePO4 was also captured at a low temperature with the optical anal. In the experiment, the researchers used Vinylene carbonate(cas: 872-36-6Quality Control of Vinylene carbonate)
Vinylene carbonate(cas: 872-36-6) belongs to esters. Alkyl carbonates find applications as solvents for lithium ion battery electrolytes and the use of high quality battery grade electrolytes having extremely low water (<10 ppm) and acid (<10 ppm) contents are critical for achieving high electrochemical performance.Quality Control of Vinylene carbonate
