Battery Powder Analysis
Powder Compaction Density: It is related to the particle size and distribution. It strongly affects the capacity, internal resistance and cycling performance of lithium-ion batteries. It can be used as an effective parameter in monitoring the variation between different batches of powder materials.
Powder Resistivity: It can be categorized into ionic resistance and electronic resistance.
Ionic resistance refers to the resistance of lithium ions in the electrolyte in the electrode pores, resistance of lithium ions through the SEI membrane, and the resistance of lithium ions and electrons.
Electronic resistance refers to the resistance of the positive and negative active materials, current collector resistance, contact resistance between the active materials, contact resistance between the active material and the current collector, and welding resistance of tabs.
In the actual battery development and production process, the ionic resistance part needs to be evaluated at the finished battery end, and the electronic resistance part can be quickly evaluated at the material and pole piece end. Therefore, the accurate evaluation of the material and the electrode electronic resistance is important for the battery.
Our system can be used to measure the ionic resistance parts evaluated at the finished battery end and electronic resistance evaluation during the material and pole piece end.
