ため固体電解質のイオン伝導性が若干低くても適度の電
流を取り出すことができる。又、単位作用面積当りの電
流を低くできるのでリチウムの不均一な析出に伴うデン
ドライトの発生が少なく二次電池化が容易である。This battery is a completely leak-free liquid, has a high energy density, can be easily made into a thin film, and can have a wide working area, so that a moderate current can be taken out even if the ionic conductivity of the solid electrolyte is slightly low. it can. Further, since the current per unit working area can be lowered, the generation of dendrites due to the non-uniform deposition of lithium is small and the secondary battery can be easily formed.

充填効率においても大きなマイナスであった。Conventionally, this type of battery structure has been a method of winding a pole group in which a negative electrode, a separator or a solid electrolyte, a positive electrode, a positive electrode current collector, and an insulator are stacked as shown in FIG. With this method, a sufficient working area cannot be obtained, and a sufficient current cannot be taken out as compared with other types of batteries, and it is required to further increase the working area. In addition, it is necessary to overlap the insulators in the entire winding length region, which is a big negative in terms of cost and active material filling efficiency.
