Soft package lithium-ion battery pack safe?

Source: 2020 - 04 - 01 hits: 3 times of soft package of lithium battery is really safe? Soft package lithium-ion battery is a kind of liquid lithium ion battery with polymer shell. In structure choose aluminum-plastic film packaging, in the case of security risk big soft battery will burst. Soft outfit lithium battery has good safety performance, light weight, large capacity, small internal resistance, good planning, etc. Soft package of internal lithium battery with rectangular and cylindrical li-ion battery internal components. Soft package lithium batteries are the main differences between the outer aluminum-plastic composite membrane, and the rectangular and cylindrical battery shell with metal materials soft package lithium-ion batteries is mainly refers to material of lithium battery shell if the outer packing, not short, it is necessary to see the battery ontology, battery steel shell weight and volume of the battery, but aluminum shell and flexible packaging is not short, but soft, flexible packaging cells than aluminum shell breaking short deformation. Soft package lithium-ion battery pack safe? In general, soft package lithium-ion batteries treasure is very safe, as long as it is not a violent touch, piercing, into the fire, the root is very safe. Normal use, in strict accordance with the instruction execution is safe. Soft package the safety of lithium-ion battery pack needs to be improved. In fact, lithium battery encapsulation is the root cause of combustion and explosion inside the battery thermal runaway. Essentially, 'thermal runaway energy is a positive feedback loop process: rising temperatures will lead to system to heat up, and then make the system temperature. Thermal escape is a very common phenomenon.
