鎖方法によると、数１０声濁オーダーの電極を形成する
には、次の様な問題点を有していた。Conventional technology and its problems The electrodes of conventional flat batteries have a [- layer V-] shaped electrode material layer formed on the current collector, and the manufacturing method is to coat the electrode material on the current collector. Alternatively, it was applied using a press or the like and cured.According to the chain method, the following problems were encountered in forming electrodes on the order of several tens of scales.
すなわちコーティングすると電極材料層の中央部で厚く
、側縁部では薄くなり、均一な厚みを有する電極材料層
を得ることが出来なかった０またプレスする方法は表面
に凸凹を有する電極材料を圧縮するため電板材料層の密
度が不均一なものとなった。In other words, when coating, the electrode material layer becomes thick at the center and thinner at the side edges, making it impossible to obtain an electrode material layer with a uniform thickness.In addition, the pressing method compresses the electrode material that has uneven surfaces. Therefore, the density of the electric board material layer became non-uniform.

いた。In addition, when forming a V-shaped electrode material layer by hardening a solid electrolyte material mixed with an electrochemical reactant and curing it with light or ionizing radiation, electrochemical Since the reactant blocks light rays, a thick electrode material layer of several tens of micrometers or more has the disadvantage that the curing speed is extremely slow and productivity is poor.

った。Additionally, the further the MnO2 contained in the electrode material layer is from the current collector, the longer the electron conduction path to the current collector, and a large amount of conductive carbon is required to increase the utilization rate during high rate discharge. However, it is known that a large amount of conductive carbon is not required in areas close to the current collector, but since the electrode material layer of conventional electrodes was one layer, the amount of MnO2 filled in the layer could not be changed. It was impossible to increase the amount of conductive carbon in the areas near the current collector, while it was small in the areas far from the current collector.
