Title:
COMPOSITE PARTICLE FOR ELECTROCHEMICAL DEVICE ELECTRODE, METHOD FOR PRODUCING SAME, ELECTROCHEMICAL DEVICE ELECTRODE MATERIAL, AND ELECTROCHEMICAL DEVICE ELECTRODE
Document Type and Number:
WIPO Patent Application WO/2007/032374
Kind Code:
A1
Abstract:
Composite particles for electrochemical device electrodes containing an electrode active material, a conductive material and a binder, while having a volume average particle diameter of 1-500 μm. The composite particles have a tensile bond strength of not less than 8,000 N/m2 when compressed for 5 seconds at 4.0 MPa at 70˚C, a tensile bond strength of not more than 200 N/m2 when compressed for 60 seconds at 0.1 MPa at 25˚C, and a tensile bond strength of not more than 3,000 N/m2 when compressed for 60 seconds at 0.5 MPa at 25˚C.
