Battery electrode roller pressing refers to the process of applying pressure to the electrode materials, effectively compressing them together to form a dense and uniform structure. The primary purpose of this technique is to enhance the performance of the battery by improving the electrode's adhesion, uniformity, and overall conductivity.
The roller pressing process directly influences the porosity of the electrode by compacting the active material particles. By carefully controlling the roller pressing parameters, it is possible to achieve the desired level of porosity, which directly impacts the battery's power and energy density. 4. Increased Electrode Conductivity:
A roller failure can result in costly shutdowns. Today, the roller materials used for the production of lithium ion battery cathode powder are ceramic rollers.
The electrode sheets, which are typically made of various active materials like lithium cobalt oxide (LiCoO2) or lithium iron phosphate (LiFePO4), are passed through the rollers to compress them uniformly. The pressure applied by the rollers helps to improve the electrode's packing density, thickness uniformity, and contact between layers.
The machine consists of a set of rollers that exert controlled pressure on the battery electrodes.
