FAQ
Q1: What is the difference between a roller press and a calender?
Roller press and calender are often used interchangeably in the battery industry. Both refer to equipment that compresses electrode sheets to precise thickness. The term “calender” is more commonly used in technical contexts, while “roller press” is more descriptive for industrial applications.
Q2: What materials can this roller press handle?
The machine handles both cathode (aluminum foil with LFP, NMC, LCO coatings) and anode (copper foil with graphite or silicon-carbon coatings) electrodes, with input thickness ranging from 0.5-5mm.
Q3: Does the machine support hot rolling?
Yes. Optional heating/cooling rolls are available for different material requirements. Hot rolling is particularly beneficial for cathode materials to improve adhesion and reduce cracking.
Q4: What is the typical application for this machine?
The machine is ideal for R&D, pilot lines, and medium-volume battery production. It is widely used in lithium-ion battery electrode manufacturing for EV, ESS, and consumer electronics cells.
