MANUFACTURING METHOD OF ELECTRODE FOR BATTERY

To provide a manufacturing method of an electrode for a battery capable of improving battery performance by making uniform the thickness and density of powder composed of granulation particles supplied onto a collector.SOLUTION: A manufacturing method of an electrode for a battery includes a powder supply step, a vibration step, a selection step, a movement step and a deposition step. In the powder supply step, powder 60 composed of granulation particles is supplied. In the vibration step, vibration is imparted to the powder. In the selection step, particle size of the granulation particles is adjusted to particle size passing through an opening, by passing the powder through at least one opening H1, H2. In movement step, the powder passed through the opening is moved from the outlet position P1 of the opening to a supply position P2 for supplying powder onto the surface of a collector 31. In the deposition step, powder is deposited on the surface of the collector.SELECTED DRAWING: Figure 2 【課題】集電体上に供給される造粒粒子からなる粉体の厚みおよび密度を均一にして電池性能を向上できる電池用電極の製造方法を提供する。【解決手段】電池用電極の製造方法は、粉体供給工程、振動工程、選別工程、移動工程および堆積工程を含む。粉体供給工程では、造粒粒子からなる粉体６０を供給する。振動工程では、粉体に振動を与える。選別工程では、粉体を少なくとも一つの開口部Ｈ１、Ｈ２に通すことで造粒粒子の粒子径を開口部を通過する粒子径に調整する。移動工程では、開口部を通過した粉体を開口部の出口位置Ｐ１から集電体３１の表面に粉体を供給する供給位置Ｐ２まで移動させる。堆積工程では、粉体を集電体の表面上に堆積させる。【選択図】図２
