Lithium-ion batteries (LIBs) have emerged as the most widely used energy storage devices owing to their high energy density and excellent cycling stability. However, safety issues have become a critical obstacle for the large-scale applications of LIBs in the energy storage systems and electric vehicles (EVs). Currently, LIBs use a low flash- and boiling-point organic carbonate as the electrolyte, which is extremely likely to cause firing or explosion. Although some flame-retardant additives can inhibit the combustion of electrolyte to a certain extent, it brings little effect in practical application. Therefore, the development of nonflammable electrolytes is an essential solution to …

Electrochemical impedance spectroscopy (EIS) is a powerful electrochemical characterization technology, which has been widely used in the field of electrochemical energy, such as lithium-ion batteries, supercapacitors, fuel cells, etc. Distribution of relaxation time (DRT) is an EIS deconvolution technique which does not depend on the prior knowledge of the targeted research object. Furthermore, DRT can serve to separate and analyze physical and chemical processes which are highly overlapped in their EIS data. In order to encourage the application and popularization of DRT deconvolution technology, several core questions are addressed in this paper: (1) DRT deconvolution principle, implementation steps and important …
