METHOD OF MANUFACTURING ELECTRODE

Japanese Patent JP2009238924

A

To improve productivity of an electrode having a perforated current-collector.

A resist layer 31 is formed over one surface of a current-collector material 30, while a resist layer 32 having a predetermined pattern is formed on the other surface of the current-collector material 30. Through-holes 20a, 23a are formed in the current-collector material 30 through an etching process. An electrode slurry is applied onto the current-collector material 30 formed with the through-holes 20a, 23a without removing the resist layers 31, 32. That is to say, since the through-holes 20a, 23a are closed by the resist layer 31, the electrode slurry never pass through the through-holes 20a, 23a to leak out. Thereby, the current-collector material 30 can be conveyed in the horizontal direction, whereby the productivity of an electrode can be improved. The resist layers 31, 32 are made of PVdF, and the resist layers 31, 32 are removed in a heating and drying process in which the PVdF is dissolved.
