Abstract
Official abstract text for this publication.
An electrode having excellent charge/discharge cycle characteristics and which is capable of improving a secondary battery capacity. An electrode is formed on the surface of a collector as an assembly of multiple porous domain structures that are apart from each other, the porous domain structures each having a polygonal shape without an acute angle in a planar view, the polygonal shape having a maximum diameter of 120 μm or less.
First claim
Opening claim text (preview).
The invention claimed is: 1. An electrode formed on the surface of a collector as an assembly of a plurality of porous domain structures which are spaced apart from each other, wherein each of the porous domain structures each have has a polygonal shape without an acute angle in a planar view, the polygonal shape having a maximum diameter of 120 μm or less, and each of the porous domain structures each have has a plurality of holes formed therethrough. 2. T…
