Battery Separating Film Machine Lithium Ion Battery Separating Film Machine

Product Description

Lithiumion battery separating film machine

2 Has a certain pore size and porosity to ensure low electrical resistance and high ion conductivity have a good permeability for lithium ions

3 Since the electrolyte is a polar organic solvent the film must resistant to the electrolyte has enough chemical and electrochemical stability

4 Good wettability of the electrolyte and has sufficient liquid moisture absorbent capacity

5 Has sufficient mechanical properties including puncture strength tensile strength but the thickness is as small as possible good dimensional stability and flatness

6 Good thermal stability and good automatic shutdown protection performancePower battery has higher requirements of film usually use composite film The film has small hot shrinkage or it will cause a short circuit triggering a battery thermal runaway

Description on the new process of lithium diaphragm stretching

Key points of the new processonline heat treatment of materials does not need the oven link in the old process After casting the composite can be directly fed into the drawing machine

Unwinding diameterin the new process one unwinding diameter can reach 1000MM four layers which can reach 32 layers The unwinding diameter of the old process is only 550MM four layers and it is 20 layers
