Laboratory Transfer Coater – Automatic Electrode Coating for Battery R&D
Our laboratory transfer coater is designed for coating both anode and cathode slurries onto current collectors using the transfer method. This lab battery electrode transfer coating machine fully automates unwinding, coating, guiding, drying, and rewinding. As an experimental transfer coating system for battery R&D, it supports continuous and intermittent coating, making it ideal for data collection, process validation, and small‑scale production.

What Is a Laboratory Transfer Coater?
A laboratory transfer coater is a precision instrument used to apply battery slurries onto metal foils (copper or aluminum) via a transfer‑roll mechanism. Unlike doctor blade coaters, transfer coaters mimic production‑scale coating better, providing reliable data for scale‑up. Our unit is specifically built for lithium‑ion battery electrode preparation – both positive and negative pastes can be coated uniformly.
Lab Battery Electrode Transfer Coating Machine – Key Features
This lab battery electrode transfer coating machine offers:
Digital control with HMI for easy parameter setting.
Full automation of unwind, coating, web guiding, hot‑air drying, and rewind.
Coating modes: Continuous coating and intermittent coating.
Heating system: Electric heating oven with precise temperature control.
Web guiding: Automatic edge correction to prevent foil wandering.
Production data: Parameters can be recorded and later used on production‑scale machines.
It is perfect for R&D labs, universities, and pilot lines that need to generate reliable coating data before mass production.
Experimental Transfer Coating System for Battery R&D – Applications
As an experimental transfer coating system for battery R&D, our equipment serves two main purposes:
Data collection – Coating thickness, uniformity, drying behavior, and adhesion can be studied.
Process transfer – Optimized parameters (e.g., coating gap, pump speed, oven temperature) can be directly adopted by high‑speed production coaters.
It is widely used for:
New electrode material formulation tests.
Small‑batch electrode production for prototype cells.
Quality control and reproducibility studies.
