Safety characteristics of lithium ion batteries

For the assessment indicators of safety performance of lithium-ion batteries, very strict standards have been set internationally. A qualified lithium-ion battery should meet the following conditions in terms of safety performance:

(1) Short circuit: no fire, no explosion

(2) Overcharge: no fire, no explosion

(3) Hot box test: no fire and explosion (constant temperature at 150 ℃ for 10min)

(4) Needle: no explosion (use) Ф 3mm nail penetration (battery)

(5) Plate impact: no fire, no explosion (10kg heavy object hits the battery from 1m)

(6) Incineration: no explosion (gas flame barbecue battery)
