## Abstract

A pressurized electrochemical battery and process for manufacturing the same, which comprises several connectors to at least one electrochemical cell with several electrical energy collectors that are connected to the connectors, with the electrochemical cell comprising several electrode sheets and several solid electrolyte sheets inserted between the electrode sheets, and at least one deformable chamber arranged in contact with the electrochemical cell, with the deformable chamber supplied with a fluid that deforms the chamber to apply pressure to the electrochemical cell.

## Claims

### Claim 1

A manufacturing process of a pressurized electrochemical battery comprising:
using a first roll that has an electrode sheet overlaid on a solid electrolyte sheet;
using a second roll that has another electrode sheet overlaid on another solid electrolyte sheet;
using a rotating spindle on which a deformable chamber is positioned;
alternately winding on the deformable chamber the electrode sheet with the solid electrolyte sheet and the other electrode sheet with the other solid electrolyte sheet;
encapsulating the assembly formed by the electrode sheets, solid electrolyte and the deformable chamber.

### Claim 2 (depends on 1)

The manufacturing process according to claim 1, wherein prior to encapsulation, several assemblies formed by electrode sheets, solid electrolyte, and deformable chamber are wound, winding said assemblies around each other according to a concentric distribution.

### Claim 3 (depends on 1)

The manufacturing process according to claim 1, wherein several rotating cutting dies are used to partially cut ends of the electrode sheets to obtain several electrical energy collectors.

### Claim 4 (depends on 1)

The manufacturing process according to claim 1, wherein the electrical energy collectors of one of the electrode sheets are located on one side and the electrical energy collectors of the other electrode sheets are located on the opposite side.

### Claim 5 (depends on 1)

The manufacturing process according to claim 1, wherein several rotating cutting dies are used to cut the electrode sheets without cutting solid electrolyte sheets prior to the alternately winding step.

### Claim 6 (depends on 1)

The manufacturing process according to claim 1, wherein the process is repeated to generate a product with multiple windings, incorporating the deformable chamber between each of the alternately winding step.

### Claim 7 (depends on 6)
