Abstract

Abstract A paper battery for connection to terminals protruding in same direction has positive and negative electrode plates joined together by a sealing agent therebetween formed with an insulating sheet. A hole penetrating one of the electrode plates and the insulating sheet to reach the other electrode plate and another hole penetrating the other of the electrode plates to reach the insulating sheet are provided such that not only is the battery connected properly to the terminals when it is inserted correctly but also a short circuit will be avoided even if the paper battery is inserted in upside-down direction.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 146 words
In a paper battery comprising positive and negative electrode plates adapted to respectively contact positive and negative terminals which protrude in a same direction, and a sealing agent between said electrode plates, said electrode plates being stuck together through said sealing agent, the improvement wherein said sealing agent comprises an insulating sheet, said positive electrode plate and said insulating sheet have a first hole formed therethrough, said first hole reaching said negative electrode plate, said negative electrode plate has a second hole formed therethrough, said second hole reaching said insulating sheet such that when said negative terminal is passed through said first hole, said negative terminal contacts said negative electrode plate and said positive terminal contacts said positive electrode plate, and that when said negative terminal is passed through said second hole, said negative terminal contacts said insulating sheet and is insulated from said positive terminal.
Claim 2
Dependent Claim 146 words
In a paper battery comprising positive and negative electrode plates adapted to respectively contact positive and negative terminals which protrude in a same direction, and a sealing agent between said electrode plates, said electrode plates being stuck together through said sealing agent, the improvement wherein said sealing agent comprises an insulating sheet, said positive electrode plate and said insulating sheet have a first hole formed therethrough, said first hole reaching said negative electrode plate, said negative electrode plate has a second hole formed therethrough, said second hole reaching said insulating sheet such that when said negative terminal is passed through said first hole, said negative terminal contacts said negative electrode plate and said positive terminal contacts said positive electrode plate, and that when said negative terminal is passed through said second hole, said negative terminal contacts said insulating sheet and is insulated from said positive terminal.
Claim 3
Dependent Claim 40 words
