| Outline of Final Research Achievements |
In order to increase the capacity of lithium ion secondary battery, increasing thickness of electrode layer is expected. However, it is difficult because the ion transfer in the direction of through-plane is dominant factor in actual cell. From this point, foaming vertical oriented macro-pores is effective to increase the mass transport in porous electrode. In this study, as one of the approach, the method to foam macro-pore by controlling particle convection distribution with dispersed heat conduction plate in drying process of wet electrode layer was proposed. The relationships between porous structure and material, shape and drying condition were evaluated. Moreover the situation of structure forming was observed directly. From these results the possibility of this approach was confirmed.
