Advanced xEV Battery Development at CATL - (PPT)

摘要

CATL is technology driven company No. 3 of battery shipment in Wh worldwide in 2015 & 2016. There are not much choices for HE cells (300Wh/kg): -based on Si/Gr, either HV NMC or HN NMC needed to be used. There are still a lot of technical issues of HE cathode: -formation of rock salt/spinel structure on the surface hinders Li~+ transportation; -interface needs to be taken into consideration (cathode surface & CEI). CATL demonstrates that both HV & HN cathodes are ready for the next generation cells in chemistry aspect Recommended to use case by case! Fast charge might be an alternative choice other than squeezing the last drop of juice from organic solvent based Li-ion batteries.
