Production method for electrode for battery, electrode produced by production method, and battery including electrode
A production method for an electrode for a battery includes preparing a conductive substrate, and electrode material particles having ion conduction anisotropy; and producing an electrode by attaching the electrode material particles onto the conductive substrate, and applying a magnetic field in a predetermined direction.
1. A production method for an electrode for a lithium secondary battery, comprising:
preparing a conductive substrate, and lithium cobaltate particles; and
producing an electrode by attaching the lithium cobaltate particles onto the conductive substrate, and applying a magnetic field in a direction substantially parallel to the conductive substrate, an intensity of the magnetic field being equal to or higher than 12 T.
2. The production method according to claim 1 , wherein
an aspect ratio of each of the lithium cobaltate particles is equal to or higher than 1.0 and lower than 5.0.
3. The production method according to claim 2 , wherein
the aspect ratio of each of the lithium cobaltate particles is equal to or higher than 1.0 and lower than 2.5.
4. The production method according to claim 1 , wherein
in producing the electrode, after the lithium cobaltate particles are dispersed in a dispersion medium, the dispersion medium, in which the lithium cobaltate particles are dispersed, is applied to the conductive substrate so that the lithium cobaltate particles are attached onto the conductive substrate.
