As a typical chemical lithiation agent with high delithiation potential, Li 2 O or Li 2 S are mixed with cathode materials to supply extra lithium sources during the charging process.
German motor vehicle inspection association (DEKRA) reported several kinds of water-based fire-extinguishing agents such as water, F-500 and a gelling agent used in extinguishing lithium-ion traction batteries fires. The flame of power LIBs was rapidly extinguished by 1% F-500 within merely 7 s.
The inclusion of conductive carbon materials into lithium-ion batteries (LIBs) is essential for constructing an electrical network of electrodes. Considering the demand for cells in electric vehicles (e.g., higher energy density and lower cell cost), the replacement of the currently used carbon black with carbon nanotubes (CNTs) seems inevitable.
Safety issue of lithium-ion batteries (LIBs) such as fires and explosions is a significant challenge for their large scale applications. Considering the continuously increased battery energy density and wider large-scale battery pack applications, the possibility of LIBs fire significantly increases.
Generally, prelithiation agent residuals are considered dead lithium sources with negligible effect on the battery performance (Figure 10B). However, the residuals, under thermal-runaway conditions, are highly reductive and easily bring about electrolyte decomposition.
In lithium-ion batteries (LIBs), lithium ions move from the cathode to the anode upon charging and vice versa upon discharging. LIBs are changing our lives as they are being used in a wide range of applications from portable electronics to electric vehicles (EVs) .
