Summary:To provide a technique for evaluating openings of a porous secondary particles.SOLUTION: A method for evaluating openings on the surface of porous secondary particles formed by connecting a plurality of primary particles includes an evaluation step of setting a space portion obtained by subtracting a space portion after performing erosion treatment on the space portion from a space portion in the porous secondary particles obtained by binarizing an observed image of the porous secondary particles as an opening, and an evaluation step of evaluating the number and/or size of the openings.SELECTED DRAWING: Figure 3 【課題】多孔質二次粒子の開口部を評価する手法を提供する。【解決手段】複数の一次粒子が連結して形成された多孔質二次粒子の表面の開口部を評価する方法であって、多孔質二次粒子の観察像を二値化して得られる多孔質二次粒子内の空間部分から、該空間部分に対して浸食処理を行った後の空間部分を減算して得られる空間部分を開口部とし、開口部の数および大きさの少なくともいずれかを評価する評価工程を有する、多孔質二次粒子の開口部の評価方法を提供する。【選択図】図３
