MANUFACTURING METHOD OF ELECTRODE FOR SECONDARY BATTERIES

To provide a manufacturing method of an electrode for secondary batteries capable of improving adhesiveness between an electrode layer and a substrate and improving a battery capacity and quick chargeability.SOLUTION: A manufacturing method of an electrode for secondary batteries includes: a step (S10) of forming a first electrode layer with a first density on a first principal surface of a first substrate; a step (S20) of preparing a second electrode layer which is formed with a second density; a step (S40) of laminating the prepared second electrode layer on a second principal surface of the first substrate; and a step (S30) of coating at least one of the second principal surface of the first substrate and a surface of the second electrode layer in contact with the second principal surface with an electrolyte prior to the step (S40) of laminating the second electrode layer.SELECTED DRAWING: Figure 2 【課題】電極層と基材との密着性を高め、かつ、電池容量および急速充電性を向上させることが可能な二次電極用電池の製造方法を提供する。【解決手段】二次電池用電極の製造方法は、第１基材の第１主面に第１の密度で第１電極層を形成する工程（Ｓ１０）と、第２の密度に形成された第２電極層を準備する工程（Ｓ２０）と、第１基材の第２主面に、準備された第２電極層を積層する工程（Ｓ４０）と、第２電極層を積層する工程（Ｓ４０）の前に、第１基材の第２主面および第２主面に接触する第２電極層の表面の少なくとも一方に電解液を塗布する工程（Ｓ３０）と、を備える。【選択図】図２
