因や使い勝手の悪さになっていた。In the electrolyte used as a partition material in a conventional lithium secondary battery, a lithium salt is dissolved in a non-aqueous solution because an aqueous solution having high ionic conductivity cannot be used due to high reactivity of lithium. The used organic electrolyte is used. However, since the organic electrolyte is in a liquid state, the battery may be damaged or may be vaporized due to heat generated during overcharging, and there is always a danger of explosion. For this reason, it is necessary to take sufficient safety measures, and It was a cause of cost increase and poor usability.

げることが唯一の方法であった。[0004] In a lithium secondary battery, reducing the resistance of this electrolyte is an important subject to be studied. Generally, when trying to lower the electric resistance of the partition material part of the battery, the thickness of the partition material part is reduced or the area is increased. However, if the thickness of the partition material is reduced, there is a danger of a short circuit between the negative electrode material and the positive electrode material. Generally, the film thickness of the partition wall material portion is 10 to 200 μm, approximately 20 to 800 μm. Therefore, in order to further reduce the internal resistance of the battery, it is necessary to reduce the thickness of the battery. However, the relationship between the battery thickness d and the battery area S is uniquely determined around the volume V, and has a relationship of S = V / d. According to this relationship, the only way to raise the performance of the battery from its structural aspect is to reduce the thickness of the battery and lower the internal resistance.

特に重要である。As a material for the partition wall, a polymer electrolyte or a gel electrolyte is used. This is because, in order to obtain a linear lithium battery, it is necessary to manufacture even an electrolyte while preserving its shape. Here, the polymer electrolyte is an electrolyte composed of a polymer and a lithium salt, and the gel electrolyte means an electrolyte in which the polymer gels an organic solvent and can maintain its shape. Such electrolytes have relatively high ionic conductivity, wide potential window, good thin film formation, flexibility, light weight,
It has excellent features such as elasticity and transparency. Further, in a lithium secondary battery, since many of the constituent materials of the battery, such as a negative electrode material and a positive electrode material, change their volumes during operation, the flexibility and elastic properties of the polymer electrolyte and the gel electrolyte are particularly important.
