Figure 4. The characterization of adhesion strength of
acrylic acid derivative terpolymer. (a) The schematics of the
fabricating process of slurry coating; (b) the digital picture of
Fe0.5Co0.5S2 thin film
cathode prepared by LA136D; (c) the schematics of electrode peel-off
test; (d) the peel-off force of electrodes with a different binder, the
content of the binders in the electrodes are 1wt %, the electrode
thickness is about 100 μm, the tape density of different electrodes is
controlled at 3.5 mg cm−3; (e) the digital pictures of
electrodes after peel-off test; (f) the digital picture of LA136D thin
film electrode after being cut into different shapes, it is shown that
the electrode maintains excellent mechanical integrity and without any
powder materials drop after cut; (g) the demonstration of the mechanical
properties of LA136D thin film electrode, LA136D electrode shows no
electrode powder materials drop even at a high curvature; (h) the SEM
picture of LA136D electrode, it indicates that small dots of LA136D can
bond the electrode powders efficiently.
