L.; Grey, Clare P.; Baumberg, Jeremy J.; Euser, Tijmen G. published an article in Nature Communications. The title of the article was 《Hollow-core optical fibre sensors for operando Raman spectroscopy investigation of Li-ion battery liquid electrolytes》.Computed Properties of C3H2O3 The author mentioned the following in the article:
Improved anal. tools are urgently required to identify degradation and failure mechanisms in Li-ion batteries. However, understanding and ultimately avoiding these detrimental mechanisms requires continuous tracking of complex electrochem. processes in different battery components. Here, we report an operando spectroscopy method that enables monitoring the chem. of a carbonate-based liquid electrolyte during electrochem. cycling in Li-ion batteries with a graphite anode and a LiNi0.8Mn0.1Co0.1O2 cathode. By embedding a hollow-core optical fiber probe inside a lab-scale pouch cell, we demonstrate the effective evolution of the liquid electrolyte species by background-free Raman spectroscopy. The anal. of the spectroscopy measurements reveals changes in the ratio of carbonate solvents and electrolyte additives as a function of the cell voltage and show the potential to track the lithium-ion solvation dynamics. The proposed operando methodol. contributes to understanding better the current Li-ion battery limitations and paves the way for studies of the degradation mechanisms in different electrochem. energy storage systems. The experimental process involved the reaction of Vinylene carbonate(cas: 872-36-6Computed Properties of C3H2O3)
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.Computed Properties of C3H2O3
