The typical compaction method for lithium-ion battery electrodes is called Battery Electrode Calendering Machine, and it significantly affects the pore structure and, consequently, the electrochemical performance of lithium-ion battery cells.
Being able to fully manage the compaction process is crucial for the focused identification of the pore structure with the best performance.
In order to compact the electrode to various coating densities, the applied line load is tracked and changed at different speeds during continuous calendering of graphite anodes and lithium nickel cobalt manganese oxide (NCM) cathodes.
Mercury intrusion measurements of the produced pore structures show relatively similar porosities, but very different densities of graphite and NCM. Mercury intrusion-measured porosities are compared to geometrically derived data to detect closed pores that are resistant to compaction.
The Global Battery Electrode Calendering Machine market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
The coated web is rolled to a specific thickness by PNT’s Battery Electrode Calendering MachineThe most crucial aspect of rolling is properly regulating the space between the primary rolls so that an even lip pressure is provided to the electrode as a whole.
PNT controls the position of the lower roll using a hydraulic servo control system, which guarantees consistency to within 1 mm.Hot rolling can be used to achieve a higher pressure rate when rolling the anode electrode, and multi-stage rolling can prevent spring-back when rolling the cathode electrode.
PNT also offers a variety of wrinkle-removal technologies, including a high-frequency induction heater and a 1000N high-tension stretching machine, among others.
