Abstract
Batteries and methods of making batteries are disclosed. In some embodiments, a battery includes a housing, a positive electrode comprising a copper material in the housing, a negative electrode in the housing, a separator between the positive electrode and the negative electrode, and an electrolytic solution comprising soluble aluminum in the housing. A method of making a battery can include providing a positive electrode comprising a copper material into a housing, adding a material comprising aluminum to an electrolytic solution, and adding the electrolytic solution into the housing.
Claims31
A battery, comprising:
- a housing;
- a positive electrode in the housing, the positive electrode comprising a copper material;
- a negative electrode in the housing;
- a separator between the positive electrode and the negative electrode;
- and
- an electrolytic solution in the housing, the electrolytic solution comprising dissolved aluminum material.
A primary alkaline battery, comprising:
- a housing;
- a positive electrode in the housing, the positive electrode comprising greater than about one weight percent of copper oxide;
- a negative electrode in the housing, the negative electrode comprising zinc;
- a separator between the positive electrode and the negative electrode;
- and
- an alkaline electrolytic solution in the housing, the electrolytic solution comprising a hydroxide material and dissolved aluminum material.
A battery, comprising:
- a housing;
- a positive electrode in the housing, the positive electrode comprising a copper material;
- a negative electrode in the housing;
- a separator between the positive electrode and the negative electrode;
- and
- an electrolytic solution in the housing, the electrolytic solution comprising a first material capable of reducing the amount of the copper material dissolved in the electrolytic solution relative to the amount of the copper material dissolved in a substantially identical electrolytic solution substantially free of the first material.
A method of making a battery, the method comprising:
- providing a positive electrode comprising a copper material into a housing;
- dissolving a material comprising aluminum to an electrolytic solution;
- and
- adding the electrolytic solution into the housing.
A method of making a battery, the method comprising:
- providing a positive electrode comprising a copper material;
- providing a first electrolytic solution;
- adding a first material to the first electrolytic solution, the first material being capable of reducing the amount of copper material dissolved in the first electrolytic solution relative to an amount of copper material dissolved in a substantially identical electrolytic solution substantially free of the first material;
- and
- incorporating the positive electrode and the electrolytic solution into the battery.
A method, comprising:
- providing an electrode comprising an active material;
- and
- reducing the solubility of the active material in an electrolytic solution.
A method of operating a battery, comprising:
- providing the battery comprising a positive electrode comprising a copper material, an electrolytic solution, and a negative electrode;
- and
- dissolving the negative electrode into the electrolytic solution during discharge of the battery,
- wherein the solubility of the copper material in the electrolytic solution is reduced.
