Microstructure engineering of nickel-rich oxide/carbon composite cathodes for fast charging of lithium-ion batteries

Notwithstanding the rapid advances in electric vehicles for supplanting internal combustion engines, the widespread adoption of lithium-ion battery-powered electric vehicles remains hindered owing to their relatively low power density, which correlates with their charging time. In this study, the io...

Description
Summary:Notwithstanding the rapid advances in electric vehicles for supplanting internal combustion engines, the widespread adoption of lithium-ion battery-powered electric vehicles remains hindered owing to their relatively low power density, which correlates with their charging time. In this study, the ionic and electronic conduction properties of electrodes were balanced by rationally designing the physical properties of the electrodes. The optimized NCA/conductive additive composite electrode required only 8.2 min for charging to 80% of the state of charge. This work paves the way to achieve extreme fast charging, thus helping to usher in a new era of electric vehicles.
