Nonaqueous electrolyte battery
View Patent ↗A nonaqueous electrolyte battery whose electrolyte can be selected from a wider range of materials can be obtained. The nonaqueous electrolyte battery comprises a positive electrode, a negative electrode and a nonaqueous electrolytic solution. At least one of the positive and negative electrodes has a collector which includes a compound containing at least one element selected from the group consisting of transition metal elements, group III elements, group IV Elements, and group V elements.
1. A nonaqueous electrolyte battery comprising:
a positive electrode including a collector;
a negative electrode; and
a nonaqueous electrolytic solution,
wherein said collector of said positive electrode comprising:
a polymer film substrate made of polyimide, and
a film comprising a nitride of a transition metal element formed on said polymer substrate, wherein nitrogen atoms filling interstitial sites in a crystal structure of said nitride.
2. A nonaqueous electrolyte battery, comprising:
a positive electrode including a collector;
a negative electrode; and
a nonaqueous electrolytic solution,
wherein said collector of said positive electrode comprising:
a polymer film substrate made of polyimide, and
a film comprising a nitride of a transition metal element formed on said polymer substrate, wherein nitrogen atoms filling interstitial sites in a crystal structure of said nitride, and wherein the transition metal element contained in said compound is titanium.
3. The nonaqueous electrolyte battery according to claim 2 , wherein
said nonaqueous electrolytic solution includes a nonaqueous electrolytic solution in which at least one solute in LiN(CF 3 SO 2 ) 2 , LiN(C 2 F 5 SO 2 ) 2 , LiPF 6 and LiBF 4 is dissolved.
