Product Introduction
This electric roller press is driven by a motor and is designed for precise rolling of sheet or coil materials, particularly for lithium-ion battery electrode sheets. The roller gap is continuously adjustable from 0 to 1.3 mm, with a customizable maximum gap of 2 mm. A pressure display allows operators to monitor the rolling force in real time, ensuring process consistency. The machine accepts materials with hardness below 50 HRC and a maximum width of 100 mm. Reference data show that a LiFePO₄ double-coated electrode sheet can be rolled from 0.205 mm to 0.09 mm, and a copper foil single-coated sheet from 0.09 mm to 0.04 mm. The compact footprint of 450×210×310 mm and standard 220V/50Hz power supply make it a practical addition to any laboratory. With motorized operation and straightforward controls, it provides uniform, high-precision rolling with minimal effort.

A roller press, also known as a calender or rolling mill, is a critical piece of equipment in lithium-ion battery manufacturing. After the electrode coating process, the coated sheets must be pressed to improve the adhesion between active material and current collector, reduce thickness, increase energy density, and enhance surface uniformity. The roller press achieves this by passing the electrode between two counter-rotating precision rollers that apply pressure, inducing plastic deformation to reach the target thickness. Laboratory electric roller presses are characterized by small size, high precision, and ease of use, making them ideal for R&D and small-batch production. The adjustable roller gap and rolling accuracy directly determine the thickness consistency of electrodes and, ultimately, the performance of the finished battery. Therefore, selecting a reliable electric roller press is essential for battery research institutions and manufacturers, as it serves as a vital bridge between formulation design, coating processes, and electrochemical performance testing.
