## Abstract

A method and apparatus for storing electricity using a rechargeable electrochemical dual-pole-cell with a coiled aluminum wire disc as the anode, graphite-based sheets as cathodes, and solid electrolyte discs. The invention teaches the use of inexpensive materials, simplified dual-pole-cell construction, assembling of dual-pole-cells into power modules, and power modules into battery power packs.

## Claims

### Claim 1

According to the present invention there is provided a method of storing electrical energy using an electrochemical dual-pole cell comprising circular discs as exterior container, an anode consisting of aluminum wire, graphite-based discs as cathode, and electrolyte based on a compound mixture of urea, sea-salt, and sodium silicate.

### Claim 2 (depends on 1)

A method according to claim 1, wherein the cathode consists of two graphite discs.

### Claim 3 (depends on 1)

A method according to claim 1, wherein the cathode consists of two discs obtained from super absorbent cellulosic material carbonized by doping with carbon ink derived from graphite powder and Polyvinyl Acetate (PVA), a vinyl polymer.

### Claim 4 (depends on 1)

A method according to claim 1, wherein the anode is a coiled disc of aluminum wire.

### Claim 5 (depends on 1)

A method according to claim 1, wherein the electrolyte is solid, consisting of a compound mixture of urea, sea-salt, and sodium silicate.

### Claim 6 (depends on 1)

A method according to claim 1, wherein the membrane separators are cellulosic sheets.

### Claim 7 (depends on 1)

An apparatus according to claim 1, wherein the fuel dual-pole cells are stacked to form a Cylindrical Power Module.

### Claim 8 (depends on 7)

An apparatus according to claim 7, wherein the Cylindrical Power Modules are arranged in rectangular grid formation and connected in series and parallel to form a Battery Power Pack.
