摘要:
A method for manufacturing a battery electrode includes mixing particles of active electrode materials, conductive additives, and binder to form a dry powder electrode material. The dry powder is then deposited onto a moving electrode current collector using a dry powder dispensing device. The dry powder is a loose powder continuously poured from the dispensing device onto a moving current collector in a roll-to-roll system where the powder remains loose on the current collector as it travels towards a compaction stage. After being poured onto the current collector, the loose dry powder is uniformly spread across the width of the moving current collector web by one or more spreading devices, such as smoothing rollers and conditioning rollers. Finally, the dry powder is compacted using a calender configured to apply pressure and/or heat to the dry powder electrode material to activate the binder and form a battery electrode.
