るという問題点を有していた。Conventional technology and its problems Non-aqueous batteries are flammable because they use organic solvents for the electrolyte, and if lithium is used for the cathode, the battery temperature may drop due to internal short circuits. The temperature rose to above the melting point of the electrolyte, and there was a risk that the electrolyte and lithium would react and cause an explosive fire. The conventional structure of such a non-aqueous battery has been a thin rectangular parallelepiped or a cylindrical shape. When the battery is installed in another device (1) If the top and bottom surfaces of the battery are in close contact with the device, almost no heat generated during use of the battery will be released from the top and bottom surfaces, causing the battery temperature to rise. For the reason mentioned above, there was a problem in that the battery caught fire.

いう危険性が増大していた。In addition, in an assembled battery made by stacking multiple non-aqueous batteries with a conventional structure, heat is not dissipated from the top and bottom surfaces of the single cells located in the middle, and the rise in temperature of the assembled battery is absorbed by the single cells. The risk of the battery catching fire was even more significant than in the previous case.
