あるが、′電池の性能で最も重要な保存性能、特に自己
放電が不可避であるという欠点を有していた。Conventional primary batteries are button-shaped or coin-shaped due to their basic structure. Cylinder type. In bottle-type and flat-plate batteries, it is inevitable that the entire amount of positive and negative electrode active materials and electrolytes used must be kept in a tight space. Naturally, it has the advantage that voltage is generated and current can be taken out as soon as the battery is assembled, but it has the disadvantage that storage performance, which is the most important aspect of battery performance, and especially self-discharge are inevitable.

題があった。In recent years, with the development of a wide variety of electronic devices including the entire field of microelectronics, the needs for batteries as power sources have become extremely diverse and sophisticated. In particular, demands for reliability in electronic devices are increasing, and there is a strong need to improve the reliability of batteries as power sources. Particularly in replacement batteries that are stored for a long period of time, there are problems in that due to self-discharge, the initial battery capacity decreases to 80 to 90 cm after one year of storage, or leaks.

ロカプセル技術が高度であシコスト面でも、瓢価になる
という欠点を有していた。In response to this, the conventional method is to confine the electrolyte in a microcapsule, insert it into the same sealed space as the positive and negative electrode active materials, and apply pressure and heat during use to destroy or dissolve the flask capsule. Although it has been widely used, the microcapsule technology is advanced and the cost is low.
本発明は、これらの欠点を除去し、艮期昧存性が極めて
