| 摘要 |
The present invention discloses a battery which is contained in a casing having an electrolyte as a conductive medium. The battery includes a first electrode of a first electric polarity formed as a single-body inserting electrode. The battery further includes a second electrode of a second electric polarity formed as a single-receiving-body with a cavity to receive the first electrode therein. The battery further includes a insulation layer for insulating the first electrode from the second electrode. In one of the preferred embodiments, the first electrode is formed as an elongated cylinder and the second electrode is formed as an elongated hollow-cylindrical shell to receive the first electrode therein. In another embodiment, the first electrode is formed as an elongated star-shape-body and the second electrode is formed as an elongated-hollow-body having a star-shape-cavity corresponding to the star-shape-body to receive the first electrode therein. In a third embodiment, the first electrode is formed as a elongated cross-shape-body and the second electrode is formed as an elongated-hollow-body having a cross-shape-cavity corresponding to the cross-shape-body to receive the first electrode therein.
