Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
34 words
In a battery having a lithium anode, carbon cathode collector, thionyl chloride catholyte, and an electrolyte dissolved in the thionyl chloride, the improvement comprising: the electrolyte including niobium pentachloride dissolved in the thionyl chloride.
Claim 2
Dependent Claim
34 words
In a battery having a lithium anode, carbon cathode collector, thionyl chloride catholyte, and an electrolyte dissolved in the thionyl chloride, the improvement comprising: the electrolyte including niobium pentachloride dissolved in the thionyl chloride.
Claim 3
Dependent Claim
37 words
A combination as claimed in claim 1 including: the amount of niobium pentachloride being sufficient to absorb the number of electrons released by the lithium in the battery under a load until the battery is completely dead.
