Abstract
Abstract The present invention concerns a bipolar storage battery. The storage battery (10) consists of bipolar elements (12) in consecutive mutual contact, each element comprising a plate (13) of electrically conductive material which has been coated on one side with a positive active compound (14) and on the other side with a negative active compound (15); of separator plates (16) containing electrolyte, which separate the adjacent bipolar elements (12); and of an enclosed gas-tight housing - (11), which surrounds the bipolar elements (12) placed in consecutive contact The edges of the bipolar element plates (13) are at least partially apart from the walls of the housing - (11) so that no continuous, sealing contact is established between the walls of the housing (11) and the plates (13).

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
122 words
A bipolar storage battery consisting of bipolar elements - (12) in consecutive mutual contact, each element comprising a plate (13) of electrically conductive material which has been coated on one side with a positive active compound - (14) and on the other side with a negative active compound (15); of separator plates (16) containing electrolyte, which separate the adjacent bipolar elements (12); and of an enclosed gas-tight housing (11), which surrounds said bipolar elements (12) placed in consecutive contact, characterized in that the edges of the bipolar element plates - (13) are at least partially apart from the walls of the housing (11) so that no continuous, sealing contact is established between the walls of the housing (11) and the plates (13).
Claim 2
Dependent Claim
122 words
A bipolar storage battery consisting of bipolar elements - (12) in consecutive mutual contact, each element comprising a plate (13) of electrically conductive material which has been coated on one side with a positive active compound - (14) and on the other side with a negative active compound (15); of separator plates (16) containing electrolyte, which separate the adjacent bipolar elements (12); and of an enclosed gas-tight housing (11), which surrounds said bipolar elements (12) placed in consecutive contact, characterized in that the edges of the bipolar element plates - (13) are at least partially apart from the walls of the housing (11) so that no continuous, sealing contact is established between the walls of the housing (11) and the plates (13).
