摘要: Abstract Concerning Li-ion cells it is demonstrated by overcharging tests both on the shelf in a fume-hood and an accelerating rate calorimeter that application of reduced pressure moment thermal runaway accident can prevent fire particular cell explosion, caused electrolyte. Within experiment, pouch-bag (88 mAh 264 mAh) composed graphite NMC (LiNi 1/3 Mn Co O 2 ) were overcharged 10 C order to induce runaway. In spite strong temperature increase, remains tightly close during without any or explosion case vacuum application.
