Shanghai Metal Corporation is a leading battery separator manufacturer and supplier.
Lithium battery separator is a porous thin film located between the positive and negative electrodes of a lithium battery. Its main function is to isolate the positive and negative electrodes of the battery, prevent short circuits, and ensure that lithium ions pass through the microporous channels normally during charging and discharging to ensure the normal operation of the battery. The performance of the separator has a significant impact on key indicators such as internal resistance, capacity, cycling performance, charging and discharging current density, and safety of lithium-ion batteries.
The technical content of the diaphragm is very high, and there are many performance indicators. Generally speaking, high-end thin film products have reasonable pore size and distribution, which can reduce internal resistance, flatten current, and effectively ensure battery energy density and cycling performance. In terms of safety, the improvement of puncture resistance and tensile strength can enhance the stability of the material. In addition, good thermal stability and spontaneous protection mechanism can avoid risk accidents such as battery short circuits.
Recent years, we also developed 4μm thickness, high temperature resistance, adhesive functional, microporous self-closing and semi-solid.
