Thermal runaway of large automotive Li-ion batteries
Damaged or heavily over-heated Li-ion batteries in electric vehicles can transit into a thermal runaway reaction with further heat and gas release. The heat may cause a battery fire and fast gas release may damage the battery-pack casing. To characterise heat and gas release of large automotive Li-ion cells, a heav
Building better electric batteries for battery electric vehicles
The Chinese battery-electric vehicle (BEV) battery-pack market is the largest and possibly most advanced in the world.Since 2019, its manufacturers have made unexpected leaps in technology in serial production, such as the use of NMC811 as cathode material in the latest generation of NMC (nickel manganese cobalt oxide)-based cells.
Materials for lithium-ion battery safety | Science Advances
Lithium-ion batteries (LIBs) have been widely used in electric vehicles, portable devices, grid energy storage, etc., especially during the past decades because of their high specific energy densities and stable cycling performance (1–8).Since the commercialization of LIBs in 1991 by Sony Inc., the energy density of LIBs has been aggressively increased.
