Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
77 words
A battery comprising: energy storage means for storing energy and for providing energy in response to exposure to at least one activating gas; and tape sealing means comprising at least two tape portions being removably adhesively affixed to a surface of the battery for incrementally controlling the amount of one or more activating gases provided to the energy storage means by removing one or more of the at least two tape portions of the tape sealing means.
Claim 2
Dependent Claim
77 words
A battery comprising: energy storage means for storing energy and for providing energy in response to exposure to at least one activating gas; and tape sealing means comprising at least two tape portions being removably adhesively affixed to a surface of the battery for incrementally controlling the amount of one or more activating gases provided to the energy storage means by removing one or more of the at least two tape portions of the tape sealing means.
Claim 3
Dependent Claim
58 words
A battery, comprising: energy storage means for storing energy and for providing energy in response to exposure to at least one activating gas; and tape sealing means comprising at least two portions being removably adhesively affixed contiguous to an outer casing of the battery for selectively limiting the at least one activating gas from reaching said energy means.
Claim 4
Dependent Claim
58 words
A battery, comprising: energy storage means for storing energy and for providing energy in response to exposure to at least one activating gas; and tape sealing means comprising at least two portions being removably adhesively affixed contiguous to an outer casing of the battery for selectively limiting the at least one activating gas from reaching said energy means.
Claim 5
Dependent Claim
54 words
A battery, comprising: energy storage means for storing energy and for providing energy in response to exposure to an atmosphere; and tape sealing means for comprising a plurality of tape portions being removably adhesively fixed to the battery so as to selectively and incrementally control exposure of said energy storage means to the atmosphere.
Claim 6
Dependent Claim
54 words
A battery, comprising: energy storage means for storing energy and for providing energy in response to exposure to an atmosphere; and tape sealing means for comprising a plurality of tape portions being removably adhesively fixed to the battery so as to selectively and incrementally control exposure of said energy storage means to the atmosphere.
Claim 7
Dependent Claim
13 words
The battery according to claim 3 wherein said battery comprises a zinc-air battery.
Claim 8
Dependent Claim
14 words
The battery according to claim 3 wherein said energy means comprises a chemical reaction.
Claim 9
Dependent Claim
14 words
The battery according to claim 5 wherein said chemical reaction includes zinc and air.
