Abstract

A method for assembling a lithium-ion reserve battery. The method including: charging an assembled lithium-ion reserve battery, the assembled lithium-ion battery including electrodes forming a battery cell, electrolyte and a membrane separating the battery cell and the electrolyte, the electrodes being charged into a charged state; disassembling the charged lithium-ion reserve battery; rinsing and drying at least the electrodes of the disassembled lithium-ion reserve battery; and reassembling the lithium-ion reserve battery with the rinsed and dried electrodes in the charged state and without the electrolyte; wherein the reassembling includes hermetically sealing a housing containing the battery cell. A method for activating such lithium-ion battery further includes, subsequent to the reassembly, introducing the electrolyte into the battery cell to activate the lithium-ion battery.

First claim

What is claimed is:

1 . A method for assembling a lithium-ion reserve battery, the method comprising:
charging an assembled lithium-ion reserve battery, the assembled lithium-ion battery including electrodes forming a battery cell, electrolyte and a membrane separating the battery cell and the electrolyte, the electrodes being charged into a charged state; disassembling the charged lithium-ion reserve battery; rinsing and drying at least the electrodes of the disassembled lithium-ion reserve battery; and reassembling the lithium-ion reserve battery with the rinsed and dried electrodes in the charged state and without the electrolyte; wherein the reassembling includes hermetically sealing a housing containing the battery cell.

2 . The method of claim 1 , wherein the charging comprises fully charging the lithium-ion battery.

3 . The method of claim 1 , wherein:
the rinsing and drying does not include rinsing and drying the membrane; and the reassembling comprises reassembling the lithium-ion battery with a new membrane.

4 . The method of claim 1 , wherein subsequent to the disassembly, storing the electrolyte for a subsequent activation of the lithium-ion battery.

5 . The method of claim 4 , wherein the storing comprising storing the electrolyte in the hermetically sealed housing.

6 . A method for activating a lithium-ion reserve battery, the method comprising:
charging an assembled lithium-ion reserve battery, the assembled lithium-ion battery including electrodes forming a battery cell, electrolyte and a membrane separating the battery cell and the electrolyte, the electrodes being charged into a charged state; disassembling the charged lithium-ion reserve battery; rinsing and drying at least the electrodes of the disassembled lithium-ion reserve battery; reassembling the lithium-ion reserve battery with the rinsed and dried electrodes in the charged state and without the electrolyte, wherein the reassembling includes hermetically sealing a housing containing the battery cell; and subsequent to the reassembly, introducing the electrolyte into the battery cell to activate the lithium-ion battery.

7 . The method of claim 6 , wherein the charging comprises fully charging the lithium-ion battery.

8 . The method of claim 6 , wherein:
the rinsing and drying does not include rinsing and drying the membrane; and the reassembling comprises reassembling the lithium-ion battery with a new membrane.

9 . The method of claim 6 , wherein subsequent to the disassembly, storing the electrolyte for a subsequent activation of the lithium-ion battery.

10 . The method of claim 9 , wherein the storing comprising storing the electrolyte in the hermetically sealed housing.

11 . The method of claim 10 , wherein the introducing comprises heating the electrolyte and forcing the heated electrolyte under pressure into the lithium-ion battery.
