Abstract

Composite particles for electrochemical device electrodes, which contain an electrode active material and a binder. A composite particle layer formed of the composite particles has a pressure loss of 5.0 mbar or less and a dynamic repose angle of 20° or more and less than 40°.

Claims

exact text as granted — not AI-modified
1 . Composite particles for an electrochemical device electrode, comprising an electrode active material and a binder, wherein a composite particle layer formed of the composite particles has a pressure loss of 5.0 mbar or less and a dynamic repose angle of 20° or more and less than 40°. 
     
     
         2 . The composite particles for an electrochemical device electrode according to  claim 1 , comprising a water-insoluble polysaccharide polymer fiber. 
     
     
         3 . The composite particles for an electrochemical device electrode according to  claim 1 , wherein a cumulative 10% diameter (D10 diameter) is 20 μm or more and 100 μm or less in a particle diameter distribution in terms of a volume.
