Claims12
A power source comprising:
- a solid polymer and an electrolyte salt comprising a parent phenyl ring with bonds outside said parent phenyl ring to R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, and R.sub.6, where R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, and R.sub.6 each comprise a member selected from the group consisting of H, SO.sub.3 X, R'H, R'SO.sub.3 X, PO.sub.3 X, and R'PO.sub.3 X, where X comprises a cation and R' comprises an aliphatic chain, an aromatic ring system, or a combination of an aliphatic chain and an aromatic ring system.
A method for providing power, the method comprising the steps of:
- a) providing a solid polymer;
- and
- b) adding to the solid polymer an electrolyte salt comprising a parent phenyl ring with bonds outside the parent phenyl ring to R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, and R.sub.6, where R.sub.l, R.sub.2, R.sub.3, R.sub.4, R.sub.5, and R.sub.6 each comprise a member selected from the group consisting of H, SO.sub.3 X, R'H, R'SO.sub.3 X, PO.sub.3 X, and R'PO.sub.3 X, where X comprises a cation and R' comprises an aliphatic chain, an aromatic ring system, or a combination of an aliphatic chain and an aromatic ring system.
A power source comprising:
- a liquid and an electrolyte salt comprising a parent phenyl ring with bonds outside said parent phenyl ring to R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, and R.sub.6, where R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, and R.sub.6 each comprise a member selected from the group consisting of H, SO.sub.3 X, R'H, R'SO.sub.3 X, PO.sub.3 X, and R'PO.sub.3 X, where X comprises a cation and R' comprises an aliphatic chain, an aromatic ring system, or a combination of an aliphatic chain and an aromatic ring system.
A method for providing power, the method comprising the steps of:
- a) providing a liquid;
- and
- b) adding to the liquid an electrolyte salt comprising a parent phenyl ring with bonds outside the parent phenyl ring to R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, and R.sub.6, where R.sub.1, R.sub.2, R.sub.4, R.sub.5, and R.sub.6 each comprise a member selected from the group consisting of H, SO.sub.3 X, R'H, R'SO.sub.3 X, PO.sub.3 X, and R'PO.sub.3 X, where X comprises a cation and R' comprises an aliphatic chain, an aromatic ring system, or a combination of an aliphatic chain and an aromatic ring system.
