- Abstract
- Provided are a vacuum-sealing-type flexible-film primary battery and a method of manufacturing the same. The primary battery includes a battery assembly comprising a positive electrode plate including a positive electrode collector having a first conductive carbon layer disposed directly on a surface-treated inner surface of a first pouch and a positive electrode layer disposed on the first conductive carbon layer of the positive electrode collector, a negative electrode plate including a negative electrode collector having a second conductive carbon layer disposed directly on a surface-treated inner surface of a second pouch and a negative electrode layer disposed on the second conductive carbon layer of the negative electrode collector, and an adhesion/post-injection polymer electrolyte layer interposed between the positive electrode plate and the negative electrode plate, wherein the battery assembly is completely sealed. The flexible-film primary battery may employ the pouch as a collector film to improve flexibility. Also, the flexible-film primary battery may be completely sealed using the pouch to improve a retention period and cell performance. Furthermore, the flexible-film primary battery may be manufactured using a screen printing technique, thereby facilitating a roll-to-roll sequential process.
