Three-Dimensional Adhesion Map Based on Surface and Interfacial Cutting Analysis System for Predicting Adhesion Properties of Composite Electrodes

Abstract

Using a surface and interfacial cutting analysis system (SAICAS) that can measure the adhesion strength of a composite electrode at a specific depth from the surface, we can subdivide the adhesion strength of a composite electrode into two classes: (1) the adhesion strength between the Al current collector and the cathode composite electrode (FAl-Ca) and (2) the adhesion strength measured at the mid-depth of the cathode composite electrode (Fmid). Both adhesion strengths, FAl-Ca and Fmid, increase with increasing electrode density and loading level. From the SAICAS measurement, we obtain a mathematical equation that governs the adhesion strength of the composite electrodes. This equation revealed a maximum accuracy of 97.2% and 96.1% for FAl-Ca and Fmid, respectively, for four randomly chosen composite electrodes varying in electrode density and loading level.

Highly rough copper current collector: improving adhesion property between a silicon electrode and current collector for flexible lithium-ion batteries

“…This technique can measure the adhesion strength at a specic depth by cutting the electrode with a micro blade. 19,20 We found that the interfacial adhesion strength of the Si/rCu/622 was still higher than that of the Si/ fCu/622 (Si/rCu/622 ¼ 292.2 N m À1 , Si/fCu/622 ¼ 231.0 N m À1 ; Fig. S1, ESI †), but the increase of 121% was not comparable to that measured by the peel test.…”

Enhanced Surface Properties of Carbon Fiber Reinforced Plastic by Epoxy Modified Primer with Plasma for Automotive Applications

“…The EMP coating depth showed that P1 + EMP of 11 μm, P5 + EMP of 10.9 μm, P0 + EMP of 9.6 μm, and P10 + EMP of 8.1 μm were measured. P10 + EMP showed the best wettability and the thinnest coating layer [23].…”

Effect of carboxymethyl cellulose on the flow behavior of lithium-ion battery anode slurries and the electrical as well as mechanical properties of corresponding dry layers

“…The volume fluctuations can induce a local delamination of the electrode layer from the current collector and cracking within the layer. Hence, considerable research work dealt with the determination of adhesive strength between electrode layer and substrate [17,[33][34][35][36][37][38][39][40][41][42][43][44][45][46]. However, the cohesive strength in the electrode layer has not received much attention yet.…”
