Battery Electrode Peel and Adhesion Strength Tester

Battery Electrode Peel and Adhesion Strength Tester

SPECIFICATIONS

Precisely measure the critical adhesion strength (peel force) of electrode coatings to current collectors with our dedicated TOB-GM-B01 Peel and Adhesion Strength Tester. 

Essential for lithium-ion battery R&D and quality control, this instrument evaluates the mechanical bond integrity between the active material layer (cathode or anode coating) and its metal foil substrate (Al or Cu). Reliable peel strength measurement directly impacts battery performance and longevity by ensuring electrodes withstand manufacturing stresses (calendering, slitting, handling) and prevent delamination during cycling. Optimize your electrode formulation, coating processes, and binder selection using quantifiable adhesion data to enhance battery durability, safety, and energy density.

Product Introduction:

• The peel strength tester is controlled by computer, which is professionally used in battery diaphragm tensile strength/elongation at break/puncture strength test, etc. The test principle is to install the sample on a fixed fixture, stretch or puncture the sample at a specified speed, and evaluate the tensile strength and puncture strength of the injection product through the measured force value.
• The machine adopts high-precision force sensor, through microcomputer measurement and control technology, precision ball screw drive, efficient and silent motor drive, with simple test, accurate force value, constant speed, beautiful appearance, smooth and quiet operation and many other advantages.
