Analysis of the uses and main functions of 602030 lipo battery separator materials
The separator is one of the key inner components. The performance of the separator determines the interface structure and internal resistance of the 602030 lipo battery, and directly affects the battery's capacity, cycle and safety performance. The separator with excellent performance is of great use to improve the overall performance of the battery.
The function of the separator in lithium-ion batteries is mainly reflected in two aspects:
First, it provides safety protection for lithium-ion batteries. The separator material must first have good insulation to prevent short circuits caused by contact between the positive and negative electrodes or short circuits caused by burrs, particles, and dendrites. Therefore, the separator must have a certain tensile and puncture strength, not easy to tear, and basically maintain dimensional stability under sudden high temperature conditions, and will not melt and shrink, resulting in large-area short circuits and thermal runaway of the battery.
Second, it provides lithium-ion batteries with microporous channels to achieve charge and discharge functions and rate performance. Therefore, the separator must be a film with a high porosity and uniform micropore distribution. The properties of the material itself and the pore characteristics after film formation restrict the migration of lithium ions in the battery, which is reflected in the performance parameters of ion conductivity.
Main functions of 602030 lipo battery diaphragm
1. Insulating layer, which can effectively prevent the positive and negative electrodes from contacting each other and causing internal short circuit.
2. Semipermeable layer, which mainly exists in liquid batteries such as lithium-ion batteries, can organize the passage of relatively large molecules and only allow small-volume charged ions to pass through, so as to increase the concentration difference near the positive and negative electrodes, which is conducive to the diffusion of ions and thus improve the storage efficiency of the battery.
The ion conductivity of the 602030 lipo battery diaphragm is directly related to the overall performance of the battery. Its use of isolating the positive and negative electrodes enables the battery to limit the increase of current when it is overcharged or the temperature rises, prevents the battery from short-circuiting and causing explosion, and has the function of micropore self-closing protection, which plays a role in safety protection for battery users and equipment.
